Description

COMPOSITIONS AND METHODS COMPRISING A LIPOLYTIC ENZYME VARIANT

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of US. Provisional Application No. 61/529,811, filed August 31, 2011, which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

Lipolytic enzymes, including lipases and cutinases, have been employed in detergent cleaning compositions for the removal of oily stains. One mechanism by which lipolytic enzymes function is by hydrolyzing triglycerides to generate fatty acids. However, these enzymes are often inhibited by surfactants and other components present in cleaning composition, interfering with their ability to remove oily stains. Accordingly, the need exists for lipolytic enzymes that can function in the harsh environment of cleaning compositions.

SUMMARY OF THE INVENTION

The present invention provides improved lipolytic enzymes, especially enzymes useful for detergent compositions. Specifically, the present invention provides lipolytic enzyme variants having one or more modifications, such as a substitution, as compared to a parent lipolytic enzyme. This can be achieved by making improvements to the enzyme by improving wash performance, stability of the enzyme in detergent compositions, thermostability of the enzyme, substrate hydrolysis, expression and/or modified charge/hydrophobicity profiles that improve effectiveness of the enzyme in a wash cycle. The present invention provides variant lipolytic enzymes, including, but not limited to, variant lipase lipolytic enzymes, that are particularly well suited to and useful in a variety of cleaning applications. The invention also provides methods of cleaning using lipolytic enzyme variants of the present invention.

DESCRIPTION OF THE INVENTION

The present invention provides improved lipolytic enzymes, especially enzymes useful for detergent compositions. Specifically, the present invention provides lipolytic enzyme variants having one or more modifications, such as a substitution, as compared to a parent lipolytic enzyme. This can be achieved by making improvements to the enzyme by improving wash performance, stability of the enzyme in detergent compositions, thermostability of the enzyme and/or modified substrate hydrolysis, and/or charge/hydrophobicity profiles that improve effectiveness of the enzyme in a wash cycle. The present invention provides variant lipolytic enzymes, including, but not limited to, variant lipase lipolytic enzymes, that are particularly well suited to and useful in a variety of cleaning applications. The invention includes compositions comprising at least one of the variant lipolytic enzymes (e.g., variant lipases) set forth herein. Some such compositions comprise detergent compositions. The invention provides Thermobifida species variant lipolytic enzymes and compositions comprising one or more such variant lipases. The lipolytic enzyme variants of the present invention can be comined with other enzymes useful in detergent compositions. The invention also provides enzyme compositions having comparable or improved wash performance, as compared to known lipolytic enzymes, such as, known lipase lipolytic enzymes. The invention also provides methods of cleaning using lipolytic enzyme variants of the present invention.

The invention includes enzyme variants of lipolytic enzymes having one or more modifications from a parent lipolytic enzyme. The enzyme variants can be useful in a detergent composition by having a minimum performing index for wash performance, substrate hydrolysis, stability of the enzyme in detergent compositions and thermostability of the enzyme, while having at least one of these characteristics improved from a parent lipolytic enzyme.

Additionally, the invention provides modifications, such as a substitution, at one or more amino acid positions in a lipolytic enzyme which can be useful in a detergent composition where favorable modifications result in a minimum performing index for wash performance, substrate hydrolysis, stability of the enzyme in detergent compositions and thermostability of the enzyme, while having at least one of these characteristics improved from a parent lipolytic enzyme. These modifications are considered suitable modifications of the invention. These amino acid positions can be considered useful positions for combinatorial modifications to a parent lipolytic enzyme. Lipolytic enzyme amino acid positions found to be useful positions can be further characterized by having multiple modifications that are suitable for use in a detergent composition. For each position, greater numbers of possible suitable modifications denotes a higher productivity of a particular position.

Unless defined otherwise herein, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Although many methods and materials similar or equivalent to those described herein find use in the practice of the present invention, some methods and materials are described herein. Accordingly, the terms defined immediately below are more fully described by reference to the specification as a whole. All patents, patent applications, articles and publications mentioned herein, both supra and infra, are hereby expressly incorporated herein by reference.

Also, as used herein, the singular terms "a," "an," and "the" include the plural reference unless the context clearly indicates otherwise. Unless otherwise indicated, nucleic acids are written left to right in 5' to 3' orientation; amino acid sequences are written left to right in amino to carboxy orientation, respectively. It is to be understood that this invention is not limited to the particular methodology, protocols, and reagents described, as these may vary, depending upon the context in which they are used by those of skill in the art. It is intended that every maximum numerical limitation given throughout this specification include every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

A "protein" or "polypeptide" comprises a polymeric sequence of amino acid residues. The terms "protein" and "polypeptide" are used interchangeably herein. The single and 3-letter code for amino acids as defined in conformity with the IUPAC-IUB Joint Commission on Biochemical Nomenclature (JCBN) is used through out this disclosure. It is also understood that a polypeptide can be coded for by more than one nucleotide sequence due to the degeneracy of the genetic code. Mutations can be named by the one letter code for the parent amino acid, followed by a number and then the one letter code for the variant amino acid. For example, mutating glycine (G) at position 87 to serine (S) can be represented as "G087S" or "G87S". Multiple mutations can be indicated by inserting a "-" between the mutations. For example, mutations at positions 87 and 90 can be represented as either "G087S-A090Y" or "G87S- A90Y" or "G87S + A90Y" or "G087S + A090Y".

The terms "derived from" and "obtained from" refer not only to a lipolytic enzyme produced or producible by a strain of the organism in question, but also a lipolytic enzyme encoded by a DNA sequence isolated from such strain and produced in a host organism containing such DNA sequence. Additionally, the term refers to a lipolytic enzyme which is encoded by a DNA sequence of synthetic and/or cDNA origin and which has the identifying characteristics of the lipolytic enzyme in question. To exemplify, "lipolytic enzymes derived from Thermobifida" refers to those enzymes having lipolytic activity which are naturally produced by Thermobifida, as well as to lipolytic enzymes like those produced by Thermobifida sources but which through the use of genetic engineering techniques are produced by non-Thermobifida organisms transformed with a nucleic acid encoding the lipolytic enzymes.

As used herein, "homology" refers to sequence similarity or identity, with identity being preferred. Homology may be determined using standard techniques known in the art (See e.g., Smith and Waterman, Adv. Appl. Math. 2:482 (1981); Needleman and Wunsch, J. Mol. Biol. 48:443 (1970);

Pearson and Lipman, Proc. Natl. Acad. Sci. USA 85:2444 (1988); software programs such as GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package (Genetics Computer Group, Madison, WI); and Devereux et al., Nucl. Acid Res. 12:387-395 (1984)). One example of a useful algorithm is PILEUP. PILEUP creates a multiple sequence alignment from a group of related sequences using progressive, pair-wise alignments. It can also plot a tree showing the clustering relationships used to create the alignment. PILEUP uses a simplification of the progressive alignment method of Feng and Doolittle (See, Feng and Doolittle, J. Mol. Evol. 35:351-360 (1987)). The method is similar to that described by Higgins and Sharp (See, Higgins and Sharp, CABIOS 5: 151-153 (1989)). Useful PILEUP parameters including a default gap weight of 3.00, a default gap length weight of 0.10, and weighted end gaps. Another example of a useful algorithm is the BLAST algorithm, described by Altschul et al, (See, Altschul et al, J. Mol. Biol. 215:403-410 (1990); and Karlin and Altschul, Proc. Natl. Acad. Sci. USA 90:5873-5787 (1993)). A particularly useful BLAST program is the WU-BLAST- 2 program (See, Altschul et al, Meth. Enzymol. 266:460-480 (1996)). WU-BLAST-2 uses several search parameters, most of which are set to the default values. The adjustable parameters are set with the following values: overlap span =1, overlap fraction = 0.125, word threshold (T) = 11. The HSP S and HSP S2 parameters are dynamic values and are established by the program itself depending upon the composition of the particular sequence and composition of the particular database against which the sequence of interest is being searched. However, the values may be adjusted to increase sensitivity.

The percent sequence identity between a reference sequence and a test sequence of interest may be readily determined by one skilled in the art. The percent identity shared by polynucleotide or polypeptide sequences is determined by direct comparison of the sequence information between the molecules by aligning the sequences and determining the identity by methods known in the art. An example of an algorithm that is suitable for determining sequence similarity is the BLAST algorithm, (See, Altschul, et al, J. Mol. Biol., 215:403-410 (1990)). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information. This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence that either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. These initial neighborhood word hits act as starting points to find longer HSPs containing them. The word hits are expanded in both directions along each of the two sequences being compared for as far as the cumulative alignment score can be increased. Extension of the word hits is stopped when: the cumulative alignment score falls off by the quantity X from a maximum achieved value; the cumulative score goes to zero or below; or the end of either sequence is reached. The BLAST algorithm parameters W, T, and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a wordlength (W) of 11, the BLOSUM62 scoring matrix (See, Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89: 10915 (1992)) alignments (B) of 50, expectation (E) of 10, M'5, N'-4, and a comparison of both strands.

The BLAST algorithm then performs a statistical analysis of the similarity between two sequences (See e.g., Karlin and Altschul, supra). One measure of similarity provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability by which a match between two nucleotide or amino acid sequences would occur by chance. For example, a nucleic acid is considered similar to a lipolytic enzyme nucleic acid of this invention if the smallest sum probability in a comparison of the test nucleic acid to a lipolytic enzyme nucleic acid is less than about 0.1, more preferably less than about 0.01, and most preferably less than about 0.001. Where the test nucleic acid encodes a lipolytic enzyme polypeptide, it is considered similar to a specified lipolytic enzyme nucleic acid if the comparison results in a smallest sum probability of less than about 0.5, and more preferably less than about 0.2.

Percent "identical" or "identity" in the context of two or more nucleic acid or polypeptide sequences refers to two or more sequences that are the same or have a specified percentage of nucleic acid residues or amino acid residues, respectively, that are the same, when compared and aligned for maximum similarity, as determined using a sequence comparison algorithm or by visual inspection. "Percent sequence identity" or "% identity" or "% sequence identity or "% amino acid sequence identity" of a subject amino acid sequence to a reference (i.e., query) amino acid sequence means that the subject amino acid sequence is identical (i.e., on an amino acid-by-amino acid basis) by a specified percentage to the query amino acid sequence over a comparison length when the sequences are optimally aligned.

Thus, 80% amino acid sequence identity or 80% identity with respect to two amino acid sequences means that 80% of the amino acid residues in two optimally aligned amino acid sequences are identical.

"Percent sequence identity" or "% identity" or "% sequence identity or "% nucleotide sequence identity" of a subject nucleic acid sequence to a reference (i.e. query) nucleic acid sequence means that the subject nucleic acid sequence is identical (i.e., on a nucleotide-by-nucleotide basis for a

polynucleotide sequence) by a specified percentage to the query sequence over a comparison length when the sequences are optimally aligned. Thus, 80% nucleotide sequence identity or 80% identity with respect to two nucleic acid sequences means that 80% of the nucleotide residues in two optimally aligned nucleic acid sequences are identical.

"Optimal alignment" or "optimally aligned" refers to the alignment of two (or more) sequences giving the highest percent identity score. For example, optimal alignment of two protein sequences can be achieved by manually aligning the sequences such that the maximum number of identical amino acid residues in each sequence are aligned together or by using software programs or procedures described herein or known in the art. Optimal alignment of two nucleic acid sequences can be achieved by manually aligning the sequences such that the maximum number of identical nucleotide residues in each sequence are aligned together or by using software programs or procedures described herein or known in the art.

In some embodiments, two polypeptide sequences are deemed "optimally aligned" when they are aligned using defined parameters, such as a defined amino acid substitution matrix, gap existence penalty (also termed gap open penalty), and gap extension penalty, so as to achieve the highest similarity score possible for that pair of sequences. The BLOSUM62 scoring matrix (See, Henikoff and Henikoff, supra) is often used as a default scoring substitution matrix in polypeptide sequence alignment algorithms (e.g., BLASTP). The gap existence penalty is imposed for the introduction of a single amino acid gap in one of the aligned sequences, and the gap extension penalty is imposed for each residue position in the gap. Exemplary alignment parameters employed are: BLOSUM62 scoring matrix, gap existence penalty=l 1, and gap extension penalty=l. The alignment score is defined by the amino acid positions of each sequence at which the alignment begins and ends (e.g., the alignment window), and optionally by the insertion of a gap or multiple gaps into one or both sequences, so as to achieve the highest possible similarity score.

Optimal alignment between two or more sequences can be determined manually by visual inspection or by using a computer, such as, but not limited to for example, the BLASTP program for amino acid sequences and the BLASTN program for nucleic acid sequences (See e.g., Altschul et al., Nucleic Acids Res. 25(17):3389-3402 (1997); See also, the National Center for Biotechnology

Information (NCBI) website).

A polypeptide of interest may be said to be "substantially identical" to a parent polypeptide if the polypeptide of interest comprises an amino acid sequence having at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 99.5% sequence identity to the amino acid sequence of the parent polypeptide. The percent identity between two such polypeptides can be determined manually by inspection of the two optimally aligned polypeptide sequences or by using software programs or algorithms (e.g., BLAST, ALIGN, CLUSTAL) using standard parameters. One indication that two polypeptides are substantially identical is that the first polypeptide is immunologically cross-reactive with the second polypeptide. Typically, polypeptides that differ by conservative amino acid substitutions are immunologically cross-reactive. Thus, a polypeptide is substantially identical to a second polypeptide, for example, where the two peptides differ only by a conservative amino acid substitution or one or more conservative amino acid substitutions.

A nucleic acid of interest may be said to be "substantially identical" to a parent nucleic acid if the nucleic acid of interest comprises a nucleotide sequence having at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 99.5% sequence identity to the nucleotide sequence of the parent nucleic acid. The percent identity between two such nucleic acids can be determined manually by inspection of the two optimally aligned nucleic acid sequences or by using software programs or algorithms (e.g., BLAST, ALIGN, CLUSTAL) using standard parameters. One indication that two nucleic acid sequences are substantially identical is that the two nucleic acid molecules hybridize to each other under stringent conditions (e.g., within a range of medium to high stringency).

A nucleic acid or polynucleotide is "isolated" when it is partially or completely separated from other components, including but not limited to for example, other proteins, nucleic acids, cells, etc. Similarly, a polypeptide, protein or peptide is "isolated" when it is partially or completely separated from other components, including but not limited to for example, other proteins, nucleic acids, cells, etc. On a molar basis, an isolated species is more abundant than are other species in a composition. For example, an isolated species may comprise at least about 50%, about 70%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100% (on a molar basis) of all macromolecular species present. Preferably, the species of interest is purified to essential homogeneity (i.e., contaminant species cannot be detected in the composition by conventional detection methods). Purity and homogeneity can be determined using a number of techniques well known in the art, such as agarose or polyacrylamide gel electrophoresis of a protein or nucleic acid sample, followed by visualization upon staining. If desired, a high-resolution technique, such as high performance liquid chromatography (HPLC) or a similar means can be utilized for purification of the material.

The term "purified" as applied to nucleic acids or polypeptides generally denotes a nucleic acid or polypeptide that is essentially free from other components as determined by analytical techniques well known in the art (e.g. , a purified polypeptide or polynucleotide forms a discrete band in an

electrophoretic gel, chromatographic eluate, and/or a media subjected to density gradient centrifugation). For example, a nucleic acid or polypeptide that gives rise to essentially one band in an electrophoretic gel is "purified." A purified nucleic acid or polypeptide is at least about 50% pure, usually at least about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, about 99.5%, about 99.6%, about 99.7%, about 99.8% or more pure (e.g., percent by weight on a molar basis). In a related sense, the invention provides methods of enriching compositions for one or more molecules of the invention, such as one or more polypeptides or polynucleotides of the invention. A composition is enriched for a molecule when there is a substantial increase in the concentration of the molecule after application of a purification or enrichment technique. A substantially pure polypeptide or polynucleotide of the invention (e.g., substantially pure variant lipolytic enzyme or polynucleotide encoding a variant lipolytic enzyme of the invention, respectively) will typically comprise at least about 55%, about 60%, about 70%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98, about 99%, about 99.5% or more by weight (on a molar basis) of all macromolecular species in a particular composition.

The position of an amino acid residue in a given amino acid sequence is typically numbered herein using the numbering of the position of the corresponding amino acid residue of the Thermobifida fusca lipase Tfulip2 amino acid sequence shown in SEQ ID NO:4. The T. fusca lipase Tfulip2 amino acid sequence of SEQ ID NO:4, thus serves as a reference parent sequence. A given amino acid sequence, such as a variant lipolytic enzyme amino acid sequence described herein, can be aligned with the Tfulip2 sequence (SEQ ID NO:4) using an alignment algorithm as described herein, and an amino acid residue in the given amino acid sequence that aligns (preferably optimally aligns) with an amino acid residue in the Tfulip2 sequence can be conveniently numbered by reference to the corresponding amino acid residue in the lipase Tfulip2 sequence.

Lipolytic enzymes of the invention

As used herein, a lipolytic enzyme includes an enzyme, polypeptide, or protein exhibiting a lipid degrading capability such as a capability of degrading a triglyceride or a phospholipid. The lipolytic enzyme can be, for example, a lipase, a phospholipase, an esterase or a cutinase. Lipolytic enzymes can be lipolytic enzymes having an α/β hydrolase fold. These enzymes typically have a catalytic triad of serine, aspartic acid and histidine residues. The α/β hydrolases include lipases and cutinases. Cutinases show little, if any, interfacial activation, where lipases often undergo a conformational change in the presence of a lipid-water interface (Longhi and Cambillau(1999) Biochimica et Biophysica Acta

1441 : 185-96). An active fragment of a lipolytic enzyme is a portion of a lipolytic enzyme that retains a lipid degrading capability. An active fragment retains the catalytic triad. As used herein, lipolytic activity can be determined according to any procedure known in the art (see, e.g. , Gupta et al ,

Biotechnol. Appl. Biochem., 37:63-71, 2003; U.S. Pat. No. 5,990,069; and International Patent

Publication No. WO 96/1 8729A1).

In some embodiments, lipolytic enzymes of the present invention are α/β hydrolases. In some embodiments, lipolytic enzymes of the present invention are lipases. In some embodiments, lipolytic enzymes of the present invention are cutinases.

Productive Positions of lipolytic enzymes

The invention provides amino acid positions in a lipolytic enzyme which can be useful in a detergent composition where favorable modifications result in a minimum performing index for wash performance, substrate hydrolysis, stability of the enzyme in detergent compositions and thermostability of the enzyme, while having at least one of these characteristics improved from a parent lipolytic enzyme. These modifications are considered suitable modifications of the invention.

The stability of lipolytic enzymes of the present invention can be compared to the stability of a standard, for example, the Thermobifida fusca lipase Tfulip2 of SEQ ID NO:4.

The terms "thermal stability" and "thermostability" refer to lipases of the present disclosure that retain a specified amount of enzymatic activity after exposure to an identified temperature, often over a given period of time under conditions prevailing during the lipolytic, hydrolyzing, cleaning or other process disclosed herein, for example while exposed to altered temperatures. Altered temperatures include increased or decreased temperatures. In some embodiments, the lipases retain at least about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 92%, about 95%, about 96%, about 97%, about 98%, or about 99% lipolytic activity after exposure to altered temperatures over a given time period, for example, at least about 60 minutes, about 120 minutes, about 180 minutes, about 240 minutes, about 300 minutes, etc.

As used herein, improved properties of a variant lipolytic enzyme includes a variant lipolytic enzyme with improved or enhanced wash or cleaning performance, and/or improved or enhanced stability optionally with retained wash or cleaning performance, relative to the corresponding parent lipolytic enzyme (e.g., wild-type or naturally-occurring lipolytic enzyme). The improved properties of a variant lipolytic enzyme may comprise improved wash or cleaning performance and/or improved stability and/or improved substrate hydrolysis and/or improved expression. In some embodiments, the invention provides variant lipolytic enzymes of the invention that exhibit one of more of the following properties: improved hand wash performance, improved hand or manual dishwashing performance, improved automatic dishwashing performance, improved laundry performance, and/or improved stability relative to a reference parent lipolytic enzyme (e.g., wild-type lipolytic enzyme, such as a wild-type lipase

Lipolytic enzyme amino acid positions found to be useful positions can have different modifications that are suitable for use in a detergent composition. Modifications can include an insertion, deletion or substitution at the particular position. In one embodiment, a modification is a substitution. For each position, greater numbers of possible suitable modifications results in a higher productivity score for the position. For example, amino acid positions can have at least 75%, 40% or 15% of the modifications tested at a productive position as suitable modifications, wherein the modification meets at least one of the following suitability criteria:

a) a position wherein the minimum performance index (PI) relative to the non-modified position for expression, CS-61 micro-swatch activity at pH 8 or pH 10, activity on PNO substrate at pH 8 or pH 10, detergent stability or thermostability are greater than or equal to a PI value of 0.9, and wherein the PI value for any one of these is greater than or equal to 1.0;

b) a position wherein the minimum performance index (PI) relative to the non-modified position for expression, CS-61 micro-swatch activity at pH 8 or pH 10, activity on PNO substrate at pH 8 or pH 10, detergent stability or thermostability are greater than or equal to a PI value of 0.8, and wherein the PI value for any one of these is greater than or equal to 1.2; or

c) a position wherein the minimum performance index (PI) relative to the non-modified position for expression, CS-61 micro-swatch activity at pH 8 or pH 10, activity on PNO substrate at pH 8 or pH 10, detergent stability or thermostability are greater than or equal to a PI value of 0.5, and wherein the PI value for any one of these is greater than or equal to 1.5.

Thermobifida fusca lipase 2 set forth in SEQ ID NO: 4.

Lipolytic enzymes positions of the present invention that have at least 40% but less than 75% of the modifications tested as suitable modifications include positions 3, 12, 24, 30, 35, 49, 60, 63, 65, 72, 73, 87, 95, 98, 108, 109, 110, 112, 117, 121, 122, 131, 142, 151, 163, 165, 174, 175, 177, 182, 187, 194, 195, 212, 213, 232, 238, 248, and 256, wherein the amino acid positions of the lipase variant are numbered by correspondence with the amino acid sequence of Thermobifida fusca lipase 2 set forth in SEQ ID NO:4.

Surface modifications

The invention includes enzyme variants of lipolytic enzymes having one or more modifications at a surface exposed amino acid. Surface modifications in the enzyme variants can be useful in a detergent composition by having a minimum performing index for wash performance, stability of the enzyme in detergent compositions and thermostability of the enzyme, while having at least one of these characteristics improved from a parent lipolytic enzyme. In some embodiments, the surface modification changes the hydrophobicity and/or charge of the amino acid at that position. Hydrophobicity can be determined using techniques known in the art, such as those described in White and Wimley (White,S.H. and Wimley, W.C,. (1999) Annu. Rev. Biophys. Biomol. Struct. 28:319-65.

As used herein, "surface property" can be used in reference to electrostatic charge, as well as properties such as the hydrophobicity and hydrophilicity exhibited by the surface of a protein.

Polypeptides of the Invention

The present invention provides novel polypeptides, which may be collectively referred to as "polypeptides of the invention." Polypeptides of the invention include isolated, recombinant, substantially pure, or non-naturally occurring variant lipolytic enzyme polypeptides, including for example, variant lipolytic enzyme polypeptides, having enzymatic activity (e.g., lipolytic activity). In some embodiments, polypeptides of the invention are useful in cleaning applications and can be incorporated into cleaning compositions that are useful in methods of cleaning an item or a surface (e.g., of surface of an item) in need of cleaning.

In some embodiments, the lipolytic enzyme variant can be a variant of a parent lipolytic enzyme from the Genus Thermobifida. Various lipolytic enzymes have been found in the genus Thermobifida that have a high identity to each other and to the lipolytic enzyme from Thermobifida fusca (Tfulip2) as shown in SEQ ID NO:4. See, for example, Table 6.1 in Example 6. In other embodiments, the lipolytic enzyme variant can be a variant of a parent lipolytic enzyme from any of the genuses listed in Table 6.1, including Verrucosispora, Saccharomonospora, Streptomyces, Micromonospora, Streptosporangium, Amycolatopsis, Cellulomonas, Actinosynnema, Kribbella, Thermomonospora, Deinococcus,

Kineococcus, Nocardiopsis, Frankia, Jonesia, Pseudomonas, Acidovorax or Nocardioidaceae. In various embodiments, the lipolytic enzyme variant can be a variant of a parent lipolytic enzyme from any of the species described in Table 6.1.

In some embodiments, the lipolytic enzyme variant can be a variant having 50, 60, 70, 80, 90, 95, 96, 97, 98, 99 or 100% identity to a lipolytic enzyme from the genus Thermobifida. In various embodiments, the lipolytic enzyme variant can be a variant having 50, 60, 70, 80, 90, 95, 96, 97, 98, 99 or 100% identity to a lipolytic enzyme from any genus in Table 6.1.

In a particular embodiment, the invention is an enzyme derived from the genus Thermobifida. In a particular embodiment, the invention is an enzyme derived from a lipolytic enzyme from the species Thermobifida fusca.

Described are compositions and methods relating to lipase cloned from Thermobifida fusca (TfuLip2). The compositions and methods are based, in part, on the observation that cloned and expressed TfuLip2 has carboxylic ester hydrolase activity (acts on carboxylic acid esters) in the presence of a detergent compositions. TfuLip2 also demonstrates excellent stability in detergent compositions, even in the presence of lipolytic enzyme. These features of TfuLip2 makes it well suited for use in a variety of cleaning applications, where the enzyme can hydrolyze lipids in the presence of surfactants and other components found in detergent compositions.

While TfuLip2 shows activity against a variety of natural and synthetic substrates, the enzyme has shown a preference for C4-C16 substrates, with peak activity against C8 substrates. This specificity makes TfuLip2 well suited for hydrolysis of short, medium and long-chain triglycerides and for performing transesterification reactions involving short, medium, and long-chain fatty acid esters.

In one aspect, the present compositions and methods provide a variant TfuLip2 polypeptide. The parent TfuLip2 polypeptide was isolated from Thermobifida fusca (GENBANK Accession No.

YP_288944). The mature TfuLip2 polypeptide has the amino acid sequence of SEQ ID NO: 4. Similar, substantially identical TfuLip2 polypeptides may occur in nature, e.g. , in other strains or isolates of T. fusca. These and other recombinant TfuLip2 polypeptides are encompassed by the present compositions and methods.

In some embodiments, the invention includes an isolated, recombinant, substantially pure, or non-naturally occurring variant lipolytic enzyme having lipolytic activity, which polypeptide comprises a polypeptide sequence having at least about 85%, at least about 86%, at least about 87%, at least about 88%, at least about 89%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, at least about 99.5%, or 100% sequence identity to a parent lipolytic enzyme as provided herein. In some embodiments, the variant polypeptide is a variant having a specified degree of amino acid sequence homology to the exemplified TfuLip2 polypeptide, e.g. , at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or even at least 99% sequence homology to the amino acid sequence of SEQ ID NO: 3 or 4. Homology can be determined by amino acid sequence alignment, e.g. , using a program such as BLAST, ALIGN, or CLUSTAL, as described herein.

Also provided is an isolated, recombinant, substantially pure, or non-naturally occurring sequence which encodes a variant lipolytic enzyme having lipolytic activity, said variant lipolytic enzyme {e.g., variant lipase) comprising an amino acid sequence which differs from the amino acid sequence of SEQ ID NO:4 by no more than 50, no more than 40, no more than 30, no more than 35, no more than 25, no more than 20, no more than 19, no more than 18, no more than 17, no more than 16, no more than 15, no more than 14, no more than 13, no more than 12, no more than 11, no more than 10, no more than 9, no more than 8, no more than 7, no more than 6, no more than 5, no more than 4, no more than 3, no more than 2, or no more than 1 amino acid residue(s), wherein amino acid positions of the variant lipase are numbered according to the numbering of corresponding amino acid positions in the amino acid sequence of Thermobifida fusca lipase Tfulip2 shown in SEQ ID NO:4 as determined by alignment of the variant lipolytic enzyme amino acid sequence with the Thermobifida fusca lipase Tfulip2 amino acid sequence.

As noted above, the variant lipolytic enzyme polypeptides of the invention have enzymatic activities {e.g., lipolytic activities) and thus are useful in cleaning applications, including but not limited to, methods for cleaning dishware items, tableware items, fabrics, and items having hard surfaces {e.g., the hard surface of a table, table top, wall, furniture item, floor, ceiling, etc.). Exemplary cleaning compositions comprising one or more variant lipolytic enzyme polypeptides of the invention are described infra. The enzymatic activity {e.g., lipolytic enzyme activity) of a variant lipolytic enzyme polypeptide of the invention can be determined readily using procedures well known to those of ordinary skill in the art. The Examples presented infra describe methods for evaluating the enzymatic activity, cleaning performance, detergent stability and/or thermostability. The performance of variant lipolytic enzymes of the invention in removing stains {e.g., a lipid stain), cleaning hard surfaces, or cleaning laundry, dishware or tableware item(s) can be readily determined using procedures well known in the art and/or by using procedures set forth in the Examples.

A polypeptide of the invention can be subject to various changes, such as one or more amino acid insertions, deletions, and/or substitutions, either conservative or non-conservative, including where such changes do not substantially alter the enzymatic activity of the polypeptide. Similarly, a nucleic acid of the invention can also be subject to various changes, such as one or more substitutions of one or more nucleic acids in one or more codons such that a particular codon encodes the same or a different amino acid, resulting in either a silent variation {e.g., mutation in a nucleotide sequence results in a silent mutation in the amino acid sequence, for example when the encoded amino acid is not altered by the nucleic acid mutation) or non-silent variation, one or more deletions of one or more nucleic acids (or codons) in the sequence, one or more additions or insertions of one or more nucleic acids (or codons) in the sequence, and/or cleavage of or one or more truncations of one or more nucleic acids (or codons) in the sequence. Many such changes in the nucleic acid sequence may not substantially alter the enzymatic activity of the resulting encoded variant lipolytic enzyme compared to the variant lipolytic enzyme encoded by the original nucleic acid sequence. A nucleic acid of the invention can also be modified to include one or more codons that provide for optimum expression in an expression system (e.g., bacterial expression system), while, if desired, said one or more codons still encode the same amino acid(s).

In some embodiments, the present invention provides a genus of polypeptides comprising variant lipolytic enzyme polypeptides having the desired enzymatic activity (e.g., lipolytic enzyme activity or cleaning performance activity) which comprise sequences having the amino acid substitutions described herein and also which comprise one or more additional amino acid substitutions, such as conservative and non-conservative substitutions, wherein the polypeptide exhibits, maintains, or approximately maintains the desired enzymatic activity (e.g., lipolytic enzyme activity or lipase activity, as reflected in the cleaning activity or performance of the variant lipolytic enzyme). Amino acid substitutions in accordance with the invention may include, but are not limited to, one or more non-conservative substitutions and/or one or more conservative amino acid substitutions. A conservative amino acid residue substitution typically involves exchanging a member within one functional class of amino acid residues for a residue that belongs to the same functional class (identical amino acid residues are considered functionally homologous or conserved in calculating percent functional homology). A conservative amino acid substitution typically involves the substitution of an amino acid in an amino acid sequence with a functionally similar amino acid. For example, alanine, glycine, serine, and threonine are functionally similar and thus may serve as conservative amino acid substitutions for one another.

Aspartic acid and glutamic acid may serve as conservative substitutions for one another. Asparagine and glutamine may serve as conservative substitutions for one another. Arginine, lysine, and histidine may serve as conservative substitutions for one another. Isoleucine, leucine, methionine, and valine may serve as conservative substitutions for one another. Phenylalanine, tyrosine, and tryptophan may serve as conservative substitutions for one another.

Other conservative amino acid substitution groups can be envisioned. For example, amino acids can be grouped by similar function or chemical structure or composition (e.g., acidic, basic, aliphatic, aromatic, sulfur-containing). For instance, an aliphatic grouping may comprise: Glycine (G), Alanine (A), Valine (V), Leucine (L), Isoleucine (I). Other groups containing amino acids that are considered conservative substitutions for one another include: aromatic: Phenylalanine (F), Tyrosine (Y),

Tryptophan (W); sulfur-containing: Methionine (M), Cysteine (C); Basic: Arginine (R), Lysine (K), Histidine (H); Acidic: Aspartic acid (D), Glutamic acid (E); non-polar uncharged residues, Cysteine (C), Methionine (M), and Proline (P); hydrophilic uncharged residues: Serine (S), Threonine (T), Asparagine (N), and Glutamine (Q). Additional groupings of amino acids are well-known to those of skill in the art and described in various standard textbooks. Listing of a polypeptide sequence herein, in conjunction with the above substitution groups, provides an express listing of all conservatively substituted polypeptide sequences.

More conservative substitutions exist within the amino acid residue classes described above, which also or alternatively can be suitable. Conservation groups for substitutions that are more conservative include: valine -leucine -isoleucine, phenylalanine -tyrosine, lysine-arginine, alanine-valine, and asparagine-glutamine. Thus, for example, in some embodiments, the invention provides an isolated or recombinant variant lipolytic enzyme polypeptide (e.g., variant lipase) having lipolytic activity, said variant lipolytic enzyme polypeptide comprising an amino acid sequence having at least about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 99.5% sequence identity to the amino acid sequence of SEQ ID NO:4. A conservative substitution of one amino acid for another in a variant lipolytic enzyme of the invention is not expected to alter significantly the enzymatic activity or cleaning performance activity of the variant lipolytic enzyme. Enzymatic activity or cleaning performance activity of the resultant lipolytic enzyme can be readily determined using the standard assays and the assays described herein.

Conservatively substituted variations of a polypeptide sequence of the invention (e.g., variant lipolytic enzymes of the invention) include substitutions of a small percentage, sometimes less than about 25%, about 20%, about 15%, about 14%, about 13%, about 12%, about 11 %, about 10%, about 9%, about 8%, about 7%, or about 6% of the amino acids of the polypeptide sequence, or less than about 5%, about 4%, about 3%, about 2%, or about 1%, of the amino acids of the polypeptide sequence, with a conservatively selected amino acid of the same conservative substitution group.

Nucleic Acids of the Invention

The invention provides isolated, non-naturally occurring, or recombinant nucleic acids (also referred to herein as "polynucleotides"), which may be collectively referred to as "nucleic acids of the invention" or "polynucleotides of the invention", which encode polypeptides of the invention. Nucleic acids of the invention, including all described below, are useful in recombinant production (e.g., expression) of polypeptides of the invention, typically through expression of a plasmid expression vector comprising a sequence encoding the polypeptide of interest or fragment thereof. As discussed above, polypeptides include variant lipolytic enzyme polypeptides, including variant lipase polypeptides having enzymatic activity (e.g., lipolytic activity) which are useful in cleaning applications and cleaning compositions for cleaning an item or a surface (e.g., surface of an item) in need of cleaning.

In some embodiments, the invention provides an isolated, recombinant, substantially pure, or non-naturally occurring nucleic acid comprising a nucleotide sequence encoding any polypeptide (including any fusion protein, etc.) of the invention described above in the section entitled "Polypeptides of the Invention" and elsewhere herein. The invention also provides an isolated, recombinant, substantially pure, or non-naturally-occurring nucleic acid comprising a nucleotide sequence encoding a combination of two or more of any polypeptides of the invention described above and elsewhere herein. Also provided is an isolated, recombinant, substantially pure, or non-naturally occurring nucleic acid comprising a polynucleotide sequence which encodes a variant lipolytic enzyme having lipolytic activity, said variant lipolytic enzyme (e.g., variant lipase) comprising an amino acid sequence which differs from the amino acid sequence of SEQ ID NO:4 by no more than 50, no more than 40, no more than 30, no more than 35, no more than 25, no more than 20, no more than 19, no more than 18, no more than 17, no more than 16, no more than 15, no more than 14, no more than 13, no more than 12, no more than 11, no more than 10, no more than 9, no more than 8, no more than 7, no more than 6, no more than 5, no more than 4, no more than 3, no more than 2, or no more than 1 amino acid residue(s), wherein amino acid positions of the variant lipase are numbered according to the numbering of corresponding amino acid positions in the amino acid sequence of Thermobifida fuse a lipase Tfulip2 shown in SEQ ID NO:l as determined by alignment of the variant lipolytic enzyme amino acid sequence with the

Thermobifida fuse a lipase Tfulip2 amino acid sequence.

The present invention provides nucleic acids encoding a lipase variant of Thermobifida lipase, as described previously, wherein the amino acid positions of the lipase variant are numbered by

correspondence with the amino acid sequence of T. fusca lipase Tfulip2 set forth as SEQ ID NO:4.

Nucleic acids of the invention can be generated by using any suitable synthesis, manipulation, and/or isolation techniques, or combinations thereof. For example, a polynucleotide of the invention may be produced using standard nucleic acid synthesis techniques, such as solid-phase synthesis techniques that are well-known to those skilled in the art. The synthesis of the nucleic acids of the invention can be also facilitated (or alternatively accomplished) by any suitable method known in the art, including but not limited to chemical synthesis using the classical phosphoramidite method (See e.g., Beaucage et al. Tetrahedron Letters 22: 1859-69 (1981)); or the method described by Matthes et al. (See, Matthes et al., EMBO J. 3:801-805 (1984), as is typically practiced in automated synthetic methods. Nucleic acids of the invention also can be produced by using an automatic DNA synthesizer. Customized nucleic acids can be ordered from a variety of commercial sources (e.g., The Midland Certified Reagent Company, the Great American Gene Company, Operon Technologies Inc., and DNA2.0). Other techniques for synthesizing nucleic acids and related principles are known in the art (See e.g., Itakura et al., Ann. Rev. Biochem. 53:323 (1984); and Itakura et al, Science 198: 1056 (1984)).

Methods for Making Modified Variant Lipolytic Enzymes of the Invention

A variety of methods are known in the art that are suitable for generating modified

polynucleotides of the invention that encode variant lipolytic enzymes of the invention, including, but not limited to, for example, site-saturation mutagenesis, scanning mutagenesis, insertional mutagenesis, deletion mutagenesis, random mutagenesis, site -directed mutagenesis, and directed-evolution, as well as various other recombinatorial approaches. Methods for making modified polynucleotides and proteins (e.g., variant lipolytic enzymes) include DNA shuffling methodologies, methods based on nonhomologous recombination of genes, such as ITCHY (See, Ostermeier et al., 7:2139-44 (1999)), SCRACHY (See, Lutz et al. 98: 11248-53 (2001)), SHIPREC (See, Sieber et al, 19:456-60 (2001)), and NRR (See, Bittker et al., 20: 1024-9 (2001); Bittker et al., 101:7011-6 (2004)), and methods that rely on the use of oligonucleotides to insert random and targeted mutations, deletions and/or insertions (See, Ness et al, 20: 1251-5 (2002); Coco et al , 20: 1246-50 (2002); Zha et al, 4:34-9 (2003); Glaser et al, 149:3903-13 (1992)). Vectors, Cells, and Methods for Producing Variant Lipolytic Enzymes of the Invention

The present invention provides isolated or recombinant vectors comprising at least one polynucleotide of the invention described herein (e.g., a polynucleotide encoding a variant lipolytic enzyme of the invention described herein), isolated or recombinant expression vectors or expression cassettes comprising at least one nucleic acid or polynucleotide of the invention, isolated, substantially pure, or recombinant DNA constructs comprising at least one nucleic acid or polynucleotide of the invention, isolated or recombinant cells comprising at least one polynucleotide of the invention, cell cultures comprising cells comprising at least one polynucleotide of the invention, cell cultures comprising at least one nucleic acid or polynucleotide of the invention, and compositions comprising one or more such vectors, nucleic acids, expression vectors, expression cassettes, DNA constructs, cells, cell cultures, or any combination or mixtures thereof.

In some embodiments, the invention provides recombinant cells comprising at least one vector (e.g., expression vector or DNA construct) of the invention which comprises at least one nucleic acid or polynucleotide of the invention. Some such recombinant cells are transformed or transfected with such at least one vector. Such cells are typically referred to as host cells. Some such cells comprise bacterial cells, including, but are not limited to Bacillus sp. cells, such as B. subtilis cells. The invention also provides recombinant cells (e.g., recombinant host cells) comprising at least one variant lipolytic enzyme of the invention.

In some embodiments, the invention provides a vector comprising a nucleic acid or

polynucleotide of the invention. In some embodiments, the vector is an expression vector or expression cassette in which a polynucleotide sequence of the invention which encodes a variant lipolytic enzyme of the invention is operably linked to one or additional nucleic acid segments required for efficient gene expression (e.g., a promoter operably linked to the polynucleotide of the invention which encodes a variant lipolytic enzyme of the invention). A vector may include a transcription terminator and/or a selection gene, such as an antibiotic resistance gene that enables continuous cultural maintenance of plasmid-infected host cells by growth in antimicrobial-containing media.

An expression vector may be derived from plasmid or viral DNA, or in alternative embodiments, contains elements of both. Exemplary vectors include, but are not limited to pXX, pC194, pJHIOl, pE194, pHP13 (See, Harwood and Cutting [eds.], Chapter 3, Molecular Biological Methods for Bacillus, John Wiley & Sons [1990]; suitable replicating plasmids for B. subtilis include those listed on p. 92; See also, Perego, Integrational Vectors for Genetic Manipulations in Bacillus subtilis, in Sonenshein et al., [eds.] Bacillus subtilis and Other Gram-Positive Bacteria: Biochemistry, Physiology and Molecular Genetics, American Society for Microbiology, Washington, D.C. [1993], pp. 615-624). For expression and production of a protein of interest (e.g., variant lipolytic enzyme) in a cell, at least one expression vector comprising at least one copy of a polynucleotide encoding the modified lipolytic enzyme, and preferably comprising multiple copies, is transformed into the cell under conditions suitable for expression of the lipolytic enzyme. In some embodiments of the present invention, a polynucleotide sequence encoding the variant lipolytic enzyme (as well as other sequences included in the vector) is integrated into the genome of the host cell, while in other embodiments, a plasmid vector comprising a polynucleotide sequence encoding the variant lipolytic enzyme remains as autonomous extra-chromosomal element within the cell. The invention provides both extrachromosomal nucleic acid elements as well as incoming nucleotide sequences that are integrated into the host cell genome. The vectors described herein are useful for production of the variant lipolytic enzymes of the invention. In some embodiments, a polynucleotide construct encoding the variant lipolytic enzyme is present on an integrating vector that enables the integration and optionally the amplification of the polynucleotide encoding the variant lipolytic enzyme into the bacterial chromosome. Examples of sites for integration are well known to those skilled in the art. In some embodiments, transcription of a polynucleotide encoding a variant lipolytic enzyme of the invention is effectuated by a promoter that is the wild-type promoter for the selected precursor lipolytic enzyme. In some other embodiments, the promoter is heterologous to the precursor lipolytic enzyme, but is functional in the host cell. Specifically, examples of suitable promoters for use in bacterial host cells include, but are not limited to, for example, the amyE, amyQ, amyL, pstS, sacB, pSPAC, pAprE, pVeg, pHpall promoters, the promoter of the B.

stearothermophilus maltogenic amylase gene, the T. fusca (BAN) amylase gene, the B. subtilis alkaline lipolytic enzyme gene, the B. clausii alkaline lipolytic enzyme gene the B. pumilis xylosidase gene, the B. thuringiensis crylllA, and the B. licheniformis alpha-amylase gene. Additional promoters include, but are not limited to the A4 promoter, as well as phage Lambda P_R or P_L promoters, and the E. coli lac, trp or tac promoters.

Variant lipolytic enzymes of the present invention can be produced in host cells of any suitable

Gram-positive microorganism, including bacteria and fungi. For example, in some embodiments, the variant lipolytic enzyme is produced in host cells of fungal and/or bacterial origin. In some

embodiments, the host cells are Bacillus sp., Streptomyces sp., Escherichia sp. or Aspergillus sp. In some embodiments, the variant lipolytic enzymes are produced by Bacillus sp. host cells. Examples of Bacillus sp. host cells that find use in the production of the variant lipolytic enzymes of the invention include, but are not limited to B. licheniformis, B. lentus, B. subtilis, B. lentus, B. brevis, B.

stearothermophilus, B. alkalophilus, B. coagulans, B. circulans, B. pumilis, B. thuringiensis, B. clausii, and B. megaterium, as well as other organisms within the genus Bacillus. In some embodiments, B. subtilis host cells are used for production of variant lipolytic enzymes. U.S. Patents 5,264,366 and 4,760,025 (RE 34,606) describe various Bacillus host strains that can be used for producing variant lipolytic enzymes of the invention, although other suitable strains can be used. Several industrial bacterial strains that can be used to produce variant lipolytic enzymes of the invention include non-recombinant (i.e., wild-type) Bacillus sp. strains, as well as variants of naturally- occurring strains and/or recombinant strains. In some embodiments, the host strain is a recombinant strain, wherein a polynucleotide encoding a polypeptide of interest has been introduced into the host. In some embodiments, the host strain is a B. subtilis host strain and particularly a recombinant Bacillus subtilis host strain. Numerous B. subtilis strains are known, including, but not limited to for example, 1A6 (ATCC 39085), 168 (1A01), SB19, W23, Ts85, B637, PB 1753 through PB 1758, PB3360, JH642, 1A243 (ATCC 39,087), ATCC 21332, ATCC 6051, Mil 13, DE100 (ATCC 39,094), GX4931, PBT 110, and PEP 211strain (See e.g., Hoch et al., Genetics 73:215-228 [1973] ; See also, U.S. Patent Nos.

4,450,235 and 4,302,544, and EP 0134048, each of which is incorporated by reference in its entirety). The use of B. subtilis as an expression host cells is well known in the art (See e.g., Palva et al., Gene 19:81-87 [1982] ; Fahnestock and Fischer, J. Bacterid., 165:796-804 [1986]; and Wang et al, Gene 69:39-47 [1988]).

In some embodiments, the Bacillus host cell is a Bacillus sp. that includes a mutation or deletion in at least one of the following genes, degU, degS, degR and degQ. Preferably the mutation is in a degU gene, and more preferably the mutation is degU(Hy)32 (See e.g., Msadek et al., J. Bacteriol. 172:824-834 [1990] ; and Olmos et al., Mol. Gen. Genet. 253:562-567 [1997]). One suitable host strain is a Bacillus subtilis carrying a degU32(Hy) mutation. In some embodiments, the Bacillus host comprises a mutation or deletion in scoC4 (See e.g., Caldwell et al., J. Bacteriol. 183:7329-7340 [2001]); spoIIE (See e.g., Arigoni et al., Mol. Microbiol. 31 : 1407-1415 [1999]); and/or oppA or other genes of the opp operon (See e.g., Perego et al., Mol. Microbiol. 5: 173-185 [1991]). Indeed, it is contemplated that any mutation in the opp operon that causes the same phenotype as a mutation in the oppA gene will find use in some embodiments of the altered Bacillus strain of the invention. In some embodiments, these mutations occur alone, while in other embodiments, combinations of mutations are present. In some embodiments, an altered Bacillus host cell strain that can be used to produce a variant lipolytic enzyme of the invention is a Bacillus host strain that already includes a mutation in one or more of the above-mentioned genes. In addition, Bacillus sp. host cells that comprise mutation(s) and/or deletions of endogenous lipolytic enzyme genes find use. In some embodiments, the Bacillus host cell comprises a deletion of the aprE and the nprE genes. In other embodiments, the Bacillus sp. host cell comprises a deletion of 5 lipolytic enzyme genes, while in other embodiments, the Bacillus sp. host cell comprises a deletion of 9 lipolytic enzyme genes (See e.g., U.S. Pat. Appln. Pub. No. 2005/0202535, incorporated herein by reference).

Host cells are transformed with at least one nucleic acid encoding at least one variant lipolytic enzyme of the invention using any suitable method known in the art. Whether the nucleic acid is incorporated into a vector or is used without the presence of plasmid DNA, it is typically introduced into a microorganism, in some embodiments, preferably an E. coli cell or a competent Bacillus cell. Methods for introducing a nucleic acid (e.g., DNA) into Bacillus cells or E. coli cells utilizing plasmid DNA constructs or vectors and transforming such plasmid DNA constructs or vectors into such cells are well known. In some embodiments, the plasmids are subsequently isolated from E. coli cells and transformed into Bacillus cells. However, it is not essential to use intervening microorganisms such as E. coli, and in some embodiments, a DNA construct or vector is directly introduced into a Bacillus host.

Those of skill in the art are well aware of suitable methods for introducing nucleic acid or polynucleotide sequences of the invention into Bacillus cells (See e.g., Ferrari et al., "Genetics," in

Harwood et al. [eds.], Bacillus, Plenum Publishing Corp. [1989], pp. 57-72; Saunders et al, J. Bacteriol. 157:718-726 [1984]; Hoch et al, J. Bacteriol. 93:1925 -1937 [1967]; Mann et al, Current Microbiol. 13: 131-135 [1986]; Holubova, Folia Microbiol. 30:97 [1985]; Chang e? al, Mol. Gen. Genet. 168: 11-115 [1979] ; Vorobjeva et al, FEMS Microbiol. Lett. 7:261-263 [1980]; Smith et al, Appl. Env. Microbiol. 51 :634 [1986]; Fisher et al, Arch. Microbiol. 139:213-217 [1981]; and McDonald, J. Gen. Microbiol. 130:203 [1984]). Indeed, such methods as transformation, including protoplast transformation and congression, transduction, and protoplast fusion are well known and suited for use in the present invention. Methods of transformation are used to introduce a DNA construct or vector comprising a nucleic acid encoding a variant lipolytic enzyme of the present invention into a host cell. Methods known in the art to transform Bacillus cells include such methods as plasmid marker rescue

transformation, which involves the uptake of a donor plasmid by competent cells carrying a partially homologous resident plasmid (See, Contente et al., Plasmid 2:555-571 [1979]; Haima et al., Mol. Gen. Genet. 223: 185-191 [1990]; Weinrauch et al, J. Bacteriol. 154:1077-1087 [1983] ; and Weinrauch et al, J. Bacteriol. 169: 1205-1211 [1987]). In this method, the incoming donor plasmid recombines with the homologous region of the resident "helper" plasmid in a process that mimics chromosomal

transformation.

In addition to commonly used methods, in some embodiments, host cells are directly transformed with a DNA construct or vector comprising a nucleic acid encoding a variant lipolytic enzyme of the invention (i.e., an intermediate cell is not used to amplify, or otherwise process, the DNA construct or vector prior to introduction into the host cell). Introduction of the DNA construct or vector of the invention into the host cell includes those physical and chemical methods known in the art to introduce a nucleic acid sequence (e.g., DNA sequence) into a host cell without insertion into a plasmid or vector. Such methods include, but are not limited to calcium chloride precipitation, electroporation, naked DNA, liposomes and the like. In additional embodiments, DNA constructs or vector are co-transformed with a plasmid, without being inserted into the plasmid. In further embodiments, a selective marker is deleted from the altered Bacillus strain by methods known in the art (See, Stahl et al., J. Bacteriol. 158:411-418 [1984] ; and Palmeros et al, Gene 247:255 -264 [2000]).

In some embodiments, the transformed cells of the present invention are cultured in conventional nutrient media. The suitable specific culture conditions, such as temperature, pH and the like are known to those skilled in the art and are well described in the scientific literature. In some embodiments, the invention provides a culture (e.g., cell culture) comprising at least one variant lipolytic enzyme or at least one nucleic acid of the invention. Also provided are compositions comprising at least one nucleic acid, vector, or DNA construct of the invention.

In some embodiments, host cells transformed with at least one polynucleotide sequence encoding at least one variant lipolytic enzyme of the invention are cultured in a suitable nutrient medium under conditions permitting the expression of the present lipolytic enzyme, after which the resulting lipolytic enzyme is recovered from the culture. The medium used to culture the cells comprises any conventional medium suitable for growing the host cells, such as minimal or complex media containing appropriate supplements. Suitable media are available from commercial suppliers or may be prepared according to published recipes (See e.g., the catalogues of the American Type Culture Collection). In some embodiments, the lipolytic enzyme produced by the cells is recovered from the culture medium by conventional procedures, including, but not limited to for example, separating the host cells from the medium by centrifugation or filtration, precipitating the proteinaceous components of the supernatant or filtrate by means of a salt (e.g., ammonium sulfate), chromatographic purification (e.g., ion exchange, gel filtration, affinity, etc.). Any method suitable for recovering or purifying a variant lipolytic enzyme finds use in the present invention.

In some embodiments, a variant lipolytic enzyme produced by a recombinant host cell is secreted into the culture medium. A nucleic acid sequence that encodes a purification facilitating domain may be used to facilitate purification of soluble proteins. A vector or DNA construct comprising a

polynucleotide sequence encoding a variant lipolytic enzyme may further comprise a nucleic acid sequence encoding a purification facilitating domain to facilitate purification of the variant lipolytic enzyme (See e.g., Kroll et al., DNA Cell Biol. 12:441-53 [1993]). Such purification facilitating domains include, but are not limited to, for example, metal chelating peptides such as histidine-tryptophan modules that allow purification on immobilized metals (See, Porath, Protein Expr. Purif. 3:263-281 [1992]), protein A domains that allow purification on immobilized immunoglobulin, and the domain utilized in the FLAGS extension/affinity purification system (e.g., protein A domains available from Immunex Corp., Seattle, WA). The inclusion of a cleavable linker sequence such as Factor XA or enterokinase (e.g., sequences available from Invitrogen, San Diego, CA) between the purification domain and the heterologous protein also find use to facilitate purification.

Assays for detecting and measuring the enzymatic activity of an enzyme, such as a variant lipolytic enzyme of the invention, are well known. Various assays for detecting and measuring activity of lipolytic enzymes (e.g., variant lipolytic enzymes of the invention), are also known to those of ordinary skill in the art. In particular, assays available for measuring lipolytic enzyme activity include those described in Example 1.

A variety of methods can be used to determine the level of production of a mature lipolytic enzyme (e.g., mature variant lipolytic enzymes of the present invention) in a host cell. Such methods include, but are not limited to, for example, methods that utilize either polyclonal or monoclonal antibodies specific for the lipolytic enzyme. Exemplary methods include, but are not limited to enzyme- linked immunosorbent assays (ELISA), radioimmunoassays (RIA), fluorescent immunoassays (FIA), and fluorescent activated cell sorting (FACS). These and other assays are well known in the art (See e.g. , Maddox et al., J. Exp. Med. 158: 1211 [1983]).

In some other embodiments, the invention provides methods for making or producing a mature variant lipolytic enzyme of the invention. A mature variant lipolytic enzyme does not include a signal peptide or a propeptide sequence. Some methods comprise making or producing a variant lipolytic enzyme of the invention in a recombinant bacterial host cell, such as for example, a Bacillus sp. cell (e.g., a B. subtilis cell). In some embodiments, the invention provides a method of producing a variant lipolytic enzyme of the invention, the method comprising cultivating a recombinant host cell comprising a recombinant expression vector comprising a nucleic acid encoding a variant lipolytic enzyme of the invention under conditions conducive to the production of the variant lipolytic enzyme. Some such methods further comprise recovering the variant lipolytic enzyme from the culture.

In some embodiments the invention provides methods of producing a variant lipolytic enzyme of the invention, the methods comprising: (a) introducing a recombinant expression vector comprising a nucleic acid encoding a variant lipolytic enzyme of the invention into a population of cells (e.g., bacterial cells, such as B. subtilis cells); and (b) culturing the cells in a culture medium under conditions conducive to produce the variant lipolytic enzyme encoded by the expression vector. Some such methods further comprise: (c) isolating the variant lipolytic enzyme from the cells or from the culture medium.

As used herein, "wash performance" of a lipolytic enzyme (e.g., a variant lipolytic enzyme of the invention) refers to the contribution of the lipolytic enzyme to washing that provides additional cleaning performance to the detergent as compared to the detergent without the addition of the variant lipolytic enzyme to the composition. Wash performance is compared under relevant washing conditions. In some test systems, other relevant factors, such as detergent composition, sud concentration, water hardness, washing mechanics, time, pH, and/or temperature, can be controlled in such a way that condition(s) typical for household application in a certain market segment (e.g., hand or manual dishwashing, automatic dishwashing, dishware cleaning, tableware cleaning, fabric cleaning, etc.) are imitated.

In some embodiments, the fabric and home care product composition is a granular or powder laundry detergent.

In some embodiments, the fabric and home care product composition is a liquid laundry detergent or a dish washing detergent.

It is intended that the fabric and home care product is provided in any suitable form, including a fluid or solid. The fabric and home care product can be in the form of a unit dose pouch, especially when in the form of a liquid, and typically the fabric and home care product is at least partially, or even completely, enclosed by a water-soluble pouch. In addition, in some embodiments of the fabric and home care products comprising at least one lipolytic enzyme variant, the fabric and home care product may have any combination of parameters and/or characteristics detailed above.

In some

embodiments, granular compositions are in "compact" form; in some embodiments, liquid compositions are in a "concentrated" form. As used herein, the term "detergent composition" or "detergent formulation" is used in reference to a composition intended for use in a wash medium for the cleaning of soiled or dirty objects, including particular fabric and/or non-fabric objects or items. Such compositions of the present invention are not limited to any particular detergent composition or formulation. Indeed, in some embodiments, the detergents of the invention comprise at least one variant lipolytic enzyme of the invention and, in addition, one or more surfactants, transferase(s), hydrolytic enzymes, oxido reductases, builders (e.g., a builder salt), bleaching agents, bleach activators, bluing agents, fluorescent dyes, caking inhibitors, masking agents, enzyme activators, antioxidants, and/or solubilizers. In some instances, a builder salt is a mixture of a silicate salt and a phosphate salt, preferably with more silicate (e.g., sodium metasilicate) than phosphate (e.g., sodium tripolyphosphate). Some compositions of the invention, such as, but not limited to, cleaning compositions or detergent compositions, do not contain any phosphate (e.g., phosphate salt or phosphate builder).

Unless otherwise noted, all component or composition levels provided herein are made in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.

Enzyme components weights are based on total active protein. All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated. In the exemplified detergent compositions, the enzymes levels are expressed by pure enzyme by weight of the total composition and unless otherwise specified, the detergent ingredients are expressed by weight of the total compositions.

As indicated herein, in some embodiments, the cleaning compositions of the present invention further comprise adjunct materials including, but not limited to, surfactants, builders, bleaches, bleach activators, bleach catalysts, other enzymes, enzyme stabilizing systems, chelants, optical brighteners, soil release polymers, dye transfer agents, dispersants, suds suppressors, dyes, perfumes, colorants, filler salts, hydrotropes, photoactivators, fluorescers, fabric conditioners, hydrolyzable surfactants, preservatives, anti-oxidants, anti-shrinkage agents, anti-wrinkle agents, germicides, fungicides, color speckles, silvercare, anti-tarnish and/or anti-corrosion agents, alkalinity sources, solubilizing agents, carriers, processing aids, pigments, and pH control agents (See e.g., U.S. Pat.

Embodiments of specific cleaning composition materials are exemplified in detail below. In embodiments in which the cleaning adjunct materials are not compatible with the variant lipolytic enzymes of the present invention in the cleaning compositions, then suitable methods of keeping the cleaning adjunct materials and the lipolytic enzyme(s) separated (i.e., not in contact with each other) until combination of the two components is appropriate are used. Such separation methods include any suitable method known in the art (e.g., gelcaps, encapsulation, tablets, physical separation, etc.). Lipase containing detergent compositions

The detergent compositions of the invention may for example, be formulated as hand and machine laundry detergent compositions including laundry additive compositions and compositions suitable for use in the pretreatment of stained fabrics, rinse added fabric softener compositions, and compositions for use in general household hard surface cleaning operations and dishwashing operations.

The detergent composition according to the invention can be in liquid, paste, gels, bars or granular forms. The pH (measured in aqueous solution at use concentration) will usually be neutral or alkaline, e.g. in the range of 7-11, particularly 9-11. Granular compositions according to the present invention can also be in "compact form", i.e. they may have a relatively higher density than conventional granular detergents, i.e. from 550 to 950 g/1.

The present compositions can include one or more adjuvants (e.g. , surfactants that are efficient in removing lipids from fabric) and one or more lipolytic enzymes. In some embodiments, the adjuvant and lipolytic enzyme are present in a single composition. In other embodiments, the adjuvant and lipolytic enzyme are present in separate compositions that are combined before contacting an oil stain on fabric, or combined on the oil stain.

The present cleaning compositions can include one or more adjuvants (surfactants) for use in combination with a lypolytic enzyme. Suitable adjuvants can have a relatively small hydrophilic portion with no net charge and hydrophobic portion that is linear or saturated. In some embodiments, the hydrophobic portion includes at least, six, seven, eight, or nine adjacent aliphatic carbons. In some embodiments, the hydrophobic portion is cyclic. In some embodiments, the hydrophobic portion is not branched. Suitable surfactancts include sugar-based compounds and zwitterionic compounds. Suitable adjuvants are disclosed, and hereby incorporated by reference in its entirety, in WO2011078949.

Sugar-based surfactants include maltopyranosides, thiomaltopyransodies, glucopyranosides, and their derivatives. Maltose-based surfactants were generally more effective than glucose -based surfactants. In some embodiments, a preferred sugar-based surfactant has a hydrophobic tail chain length of at least 4, at least 5, at least 6, and even at least 7 carbons. The tail can be aliphatic or cyclic. The tail can be unbranched, although branching is acceptable with sufficient chain length.

Particular examples of sugar-based surfactants include nonyl- -D-maltopyranoside, decyl-β-

D-maltopyranoside, undecyl- -D-maltopyranoside, dodecyl- -D-maltopyranoside, tridecyl- -D- maltopyranoside, tetradecyl- -D-maltopyranoside, hexaecyl- -D-maltopyranoside, n-dodecyl-β-Ό- maltopyranoside and the like, 2,6-dimethyl-4-heptyl- -D-maltopyranoside, 2-propyl-l-pentyl- -D- maltopyranoside, nonyl- -D-glucopyranoside, nonyl- -D-glucopyranoside, decyl- -D-glucopyranoside, dodecyl-P-D-glucopyranoside, sucrose monododecanoate, certain cyclohexylalkyl- -D-maltosides (e.g. , the CYMAL^®s and CYGLAs), and the MEGA™ surfactants.

The adjuvant can be a zwitterionic surfactant, such as a FOS-choline. In some embodiments, the FOS-choline has a hydrophobic tail with a chain length of 12 or greater. The hydrophobic tail can be saturated and unsaturated and can be cyclic. Exemplary FOS-choline surfactants include FOS- CHOLINE^®-^, FOS-CHOLINE^®-13, FOS-CHOLINE^®-14, LYSOFOS-CHOLINE^®-14, FOS- CHOLINE^®-^, FOS-CHOLINE^®-16, FOS-MEA^®-12, DODECAFOS, ISO unsat 11-10, ISO 11-6, CYOFO, NOPOL-FOS, CYCLOFOS^® (CYMAL^®)-5, -6. -7, -8, etc., and the like.

In some cases, the adjuvant can be a sulfobetaine zwitterionic surfactant. Preferred sulfobetaine surfactants have a hydrophobic tail having at least 12 carbons, e.g. , ANZERGENT^® 3-12 and ANZERGENT^® 3-14. The zwitterionic oxides and CHAPS-based surfactants (e.g. CHAPS and CHAPSO) are also effective, typically at higher doses than the sulfobetaines.

In some cases, the adjuvant can be an anionic detergent, for example, a sarcosine. Preferred sarcosines have a hydrophobic tail having at least 10 carbons. In some cases, the adjuvant can also be deoxycholate.

The adjuvant can be present in a composition in an amount of at least .001%, at least 0.005%, at least 0.01%, at least 0.05%, at least 0.1%, or more, or at least 0.01 ppm, at least 0.05 ppm, at least 0.1 ppm, at least 0.5 ppm, at least 1 ppm, at least 5 ppm, at least 10 ppm, or more. In some cases, the adjuvant may be present in a preselected range, e.g. , about 0.001-0.01%, about 0.01-0.1%, about 0.1- 1%, or about 0.01-1 ppm, about 0.1-1 ppm, or about 1-10 ppm. In some cases, optimum activity is observed over a range, above and below which activity is reduced.

The surfactant system of the detergent can comprise nonionic, anionic, cationic, ampholytic, and/or zwitterionic surfactants. The surfactant is typically present at a level from 0.1% to 60% by weight, e.g. 1% to 40%, particularly 10-40% preferably from about 3% to about 20% by weight. The detergent will usually contain 0-50% of anionic surfactant such as linear alkylbenzenesulfonate (LAS), alpha-olefin sulfonate (AOS), alkyl sulfate (fatty alcohol sulfate) (AS), alcohol ethoxysulfate (AEOS or AES), secondary alkane sulfonates (SAS), alpha-sulfo fatty acid methyl esters, alkyl- or alkenylsuccinic acid or soap.

The detergent can comprise 0-40% of nonionic surfactant polyalkylene oxide (e.g. polyethylene oxide) condensates of alkyl phenols. Preferred nonionic surfactants are alcohol ethoxylate (AEO or AE), carboxylated alcohol ethoxylates, nonylphenol ethoxylate, alkylpolyglycoside,

alkyldimethylamineoxide, ethoxylated fatty acid monoethanolamide, fatty acid monoethanolamide, alkyl(N-methyl)-glucoseamide or polyhydroxy alkyl fatty acid amide (e.g. as described in WO

92106154).

Semi-polar nonionic surfactants are another category of nonionic surfactants which include water-soluble amine oxides containing one alkyl moiety of from about 10 to about 18 carbon atoms and 2 moieties selected from the group consisting of alkyl groups and hydroxyalkyl groups containing from about 1 to about 3 carbon atoms; water soluble phosphine oxides containing one alkyl moiety of from about 10 to about 18 carbon atoms and 2 moieties selected from the group consisting of alkyl groups and hydroxyalkyl groups containing from about 1 to about 3 carbon atoms; and water-soluble sulfoxides containing one alkyl moiety from about 10 no to about 18 carbon atoms and a moiety selected from the group consisting of alkyl and hydroxyalkyl moieties of from about 1 to about 3 carbon atoms. The amine oxide surfactants in particular include Ci₀-Ci₈ alkyl dimethyl amine oxides and C₈-Ci₂ alkoxy ethyl dihydroxy ethyl amine oxides.

The detergent composition can further comprise cationic surfactants. Cationic detersive surfactants used are those having one long-chain hydrocarbyl group. Examples of such cationic surfactants include the ammonium surfactants such as alkyl trimethyl ammonium halogenides. Highly preferred cationic surfactants are the water soluble quaternary ammonium compounds. Examples of suitable quaternary ammonium compounds include coconut trimethyl ammonium chloride or bromide; coconut methyl dihydroxy ethyl ammonium chloride or bromide; decyl triethyl ammonium chloride; decyl dimethyl hydroxyl ethyl ammonium chloride or bromide; CI 2- 15 dimethyl hydroxyl ethyl ammonium chloride or bromide; coconut dimethyl hydroxyl ethyl ammonium chloride or bromide; myristyl trimethyl ammonium methyl sulphate; lauryl dimethyl benzyl ammonium chloride or bromide; lauryl dimethyl (ethenoxy)₄ ammonium chloride or bromide; choline esters, dialkyl imidazolines.

The detergent composition can further comprise ampholytic surfactants. These surfactants can be broadly described as aliphatic derivatives of secondary or tertiary amines, or aliphatic derivatives of heterocyclic secondary and tertiary amines in which the aliphatic radical can be straight-, or branched- chain. One of the aliphatic substituent contains at least about 8 carbon atoms, typically from about 8 to about 18 carbon atoms, and at least one contains an anionic water-solubilizing group, e.g. carboxy, sulfonate, sulfate. Examples of compounds falling within this definition are sodium 3-(dodecylamino) propionate, sodium 3-(dodecylamino)- propane-1 -sulfonate, sodium 2-(dodecylamino)ethyl sulfate, sodium 2-(dimethylamino)octadecanoate, di-sodium 3-(N -carboxymethyldodecylamino)propane-I- sulfonate, disodium octadecyl-iminodiacetate, sodium l-carboxymethyl-2-undecylimidazole, and sodium N ,N-bis(2-hydroxyethyl)-2-sulfato-3-dodecoxy-propylamine. Sodium 3-(dodecylamino)propane-I- sulfonate is preferred.

Zwitterionic surfactants are also used in detergent compositions especially within laundry. These surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium or tertiary sulfonium compounds. The cationic atom in the quaternary compound can be part of a heterocyclic ring. In all of these compounds, there is at least one aliphatic group, straight chain or branched, containing from about 3 to 18 carbon atoms and at least one aliphatic substituent containing an anionic water solubilizing group, e.g. carboxy, sulfonate, sulfate, phosphate or phosphonate. Ethoxylated zwitterionic compounds in combination with zwitterionic surfactants have been particularly used for clay soil removal in laundry applications.

The detergent may contain 1-65% of a detergent builder or complexing agent such as zeolite, diphosphate, triphosphate, phosphonate, citrate, nitrilotriacetic acid (NT A), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTMPA), alkyl- or alkenylsuccinic acid, soluble silicates or layered silicates (e.g. SKS-6 from Hoechst). The detergent may also be unbuilt i.e. essentially free of detergent builder.

The detergent builders may be subdivided into phosphorus-containing and non-phosphorous- containing types. Examples of phosphorus-containing inorganic alkaline detergent builders include the water-soluble salts, especially alkali metal pyrophosphates, orthophosphates, polyphosphates and phosphonates. Examples of non-phosphorus-containing inorganic builders include water soluble alkali metal carbonates, borates and silicates as well as layered disilicates and the various types of water insoluble crystalline or amorphous alumino silicates of which zeolites is the best known representative.

Examples of suitable organic builders include alkali metal, ammonium or substituted ammonium salts of succinates, malo nates, fatty acid malonates, fatty acid sulphonates, carboxymethoxy succinates, poly acetates, carboxylates, polycarboxylates, aminopolycarboxylates and polyacetyl carboxylates.

A suitable chelant for inclusion in the detergent compositions is ethylenediamine- Ν,Ν'- disuccinic acid (EDDS) or the alkali metal, alkaline earth metal, ammonium, or substituted ammonium salts thereof, or mixtures thereof. Preferred EDDS compounds are the free acid form and the sodium or magnesium salt thereof. Examples of such preferred sodium salts of EDDS include Na2EDDS and

Na4EDDS. Examples of such preferred magnesium salts of EDDS include MgEDDS and Mg2EDDS.

The magnesium salts are the most preferred for inclusion in compositions.

The detergent may comprise one or more polymers. Examples are carboxymethylcellulose

(CMC), poly (vinylpyrrolidone) (PVP), polyethyleneglycol (PEG), poly (vinyl alcohol) (PVA), polycarboxylates such as polyacrylates, maleic/acrylic acid copolymers and lauryl methacrylate/acrylic acid copolymers.

The detergent composition may contain bleaching agents of the chlorine/bromine-type or the oxygen-type. The bleaching agents may be coated or encapsulated. Examples of inorganic

chlorine/bromine-type bleaches are lithium, sodium or calcium hypochlorite or hypobromite as well as chlorinated trisodium phosphate. The bleaching system may also comprise a hydrogen peroxide source such as perborate or percarbonate which may be combined with a peracid-forming bleach activator such as tetraacetyl-ethylenediamine (TAED) or nonanoyloxybenzenesulfonate (NOBS). Examples of organic chlorine/bromine-type bleaches are heterocyclic N-bromo and N-chloro imides such as

trichloroisocyanuric, tribromoisocyanuric, dibromoisocyanuric and dichloroisocyanuric acids, and salts thereof with water solubilizing cations such as potassium and sodium. Hydantoin compounds are also suitable. The bleaching system may also comprise peroxyacids of, e.g., the amide, imide, or sulfone type. In dishwashing detergents the oxygen bleaches are preferred, for example in the form of an inorganic persalt, preferably with a bleach precursor or as a peroxy acid compound. Typical examples of suitable peroxy bleach compounds are alkali metal perborates, both tetrahydrates and monohydrates, alkali metal percarbonates, persilicates and perphosphates. Preferred activator materials are

tetraacetylethylenediamine (TAED), nonanoyloxybenzenesulfonate (NOBS), 3,5-trimethyl- hexsanoloxybenzenesulfonate (ISONOBS) or pentaacetylglucose (PAG).

The lipase of the invention, or optionally another enzyme incorporated in the detergent composition, is normally incorporated in the detergent composition at a level from 0.00001% to 2% of enzyme protein by weight of the composition, preferably at a level from 0.0001% to 1% of enzyme protein by weight of the composition, more preferably at a level from 0.001% to 0.5% of enzyme protein by weight of the composition, even more preferably at a level from 0.01% to 0.2% of enzyme protein by weight of the composition. The detergent composition of the invention may comprise the lipase in an amount corresponding to 10-50,000 LU per gram of detergent, preferably 20-5,000 LU/g, e.g. 100-1000 LU/g. The detergent may be dissolved in water to produce a wash liquor containing lipolytic enzyme in an amount corresponding to 25-15,000 LU per liter of wash liquor, particularly 100-5000 LU/I, e.g. 300- 2000 LU/I. The amount of lipase protein may be 0.001-10 mg per gram of detergent or 0.001-100 mg per liter of wash liquor. The lipase variants of the invention are particularly suited for detergents comprising of a combination of anionic and nonionic surfactant with 70-100% by weight of anionic surfactant and 0- 30% by weight of nonionic, particularly 80-100% of anionic surfactant, and 0-20% nonionic surfactant. As further described, some preferred lipases of the invention are also suited for detergents comprising 40- 70% anionic and 30-60% non-ionic surfactant. The detergent composition may, in addition to the lipase of the invention, comprise other enzyme(s) providing cleaning performance and/or fabric care benefits, e.g. additional lipases, cutinases, proteases, hemicellulases, cellulases, peroxidases, lipolytic enzymes, metallolipolytic enzymes, xylanases, lipases, phospholipases, esterases, perhydrolases, cutinases, pectinases, pectate lyases, mannanases, keratinases, oxidoreductases, reductases, oxidases (e.g. laccases), phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases,

β-glucanases, arabinosidases, hyaluronidases, chondroitinases, laccases, and amylases.

The enzymes of the detergent composition may be stabilized using conventional stabilizing agents (e.g. a polyol such as propylene glycol or glycerol, a sugar or sugar alcohol, lactic acid, boric acid, or a boric acid derivative as e.g. an aromatic borate ester). Boronic acid or borinic acid derivatives as enzyme stabilizers include Boric acid, Thiophene-3- boronic acid, Thiophene-2- boronic acid, 4- Methylthiophene- 2-boronic acid, 5-Ethylthiophene -2 -boronic acid, 5-Methylthiophene-2-boronic acid, 5-Bromothiophene-2-boronic acid, 5-Chlorothiophene-2-boronic acid, Dibenzothiophene-l-boronic acid, Dibenzofuran-l-boronic acid, Dibenzofnran-4-boronic acid, Picoline-2-boronic acid, Diphenylborinic acid (ethanolamine complex), 5-Methoxythio-phene-2-boronic acid, Thionaphthrene-1- boronic acid, Furan-2 -boronic acid, Furan-3-boronic acid, 2,5-dimethyl- thiophene-3 -boronic acid, Benzofuran-1- boronic acid, 3-Methoxythio-phene-2-boronic acid, 5-n-Propyl-thiophene-2-boronic acid, 5- Methoxyfuran-2-boronic acid, 3-Bromothiophene-2-boronic acid, 5-Ethylfuran-2-boronic acid, 4- Carbazole ethyl boronic acid.

An optional ingredient is a suds suppresor (e.g. exemplified by silicones-alkylated polysiloxane materials, and silica-silicone mixtures, where the silica is in the form of silica aerogels and xerogels and hydrophobic silicas of various types. The suds suppressor can be incorporated as particulates, in which the suds suppressor is advantageously releasable incorporated in a water-soluble or water dispersible, substantially non surface-active detergent impermeable carrier. Alternatively the suds suppressor can be dissolved or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.

The detergent may also contain inorganic or organic softening agents. Inorganic softening agents are exemplified by the smectite clays (5% to 15%). Organic fabric softening agents (0.5% to 5%) include the water insoluble tertiary amines and their combination with mono Q₂ -Ci₄ quaternary ammonium salts and di-long-chain amides, or high molecular weight polyethylene oxide materials.

The detergent may also contain other conventional detergent ingredients such as, e.g., fabric conditioners including clays, deflocculant material, foam boosters/foam depressors (in dishwashing detergents foam depressors), anti-corrosion agents, soil-suspending or dispersing agents (0 to 10%), anti- soil-redeposition agents, dyes, dehydrating agents, bactericides, optical brighteners, abrasives, tarnish inhibitors, coloring agents, and/or encapsulated or non-encapsulated perfumes.

The cleaning compositions of the present invention are advantageously employed for example, in laundry applications, hard surface cleaning, dishwashing applications, as well as cosmetic applications such as dentures, teeth, hair and skin. In addition, due to the unique advantages of increased

effectiveness in lower temperature solutions, the enzymes of the present invention are ideally suited for laundry applications. Furthermore, the enzymes of the present invention find use in granular and liquid compositions.

The variant lipolytic enzymes of the present invention also find use in cleaning additive products.

In some embodiments, low temperature solution cleaning applications find use. In some embodiments, the present invention provides cleaning additive products including at least one enzyme of the present invention is ideally suited for inclusion in a wash process when additional bleaching effectiveness is desired. Such instances include, but are not limited to low temperature solution cleaning applications. In some embodiments, the additive product is in its simplest form, one or more lipolytic enzymes. In some embodiments, the additive is packaged in dosage form for addition to a cleaning process. In some embodiments, the additive is packaged in dosage form for addition to a cleaning process where a source of peroxygen is employed and increased bleaching effectiveness is desired. Any suitable single dosage unit form finds use with the present invention, including but not limited to pills, tablets, gelcaps, or other single dosage units such as pre-measured powders or liquids. In some embodiments, filler(s) or carrier material(s) are included to increase the volume of such compositions. Suitable filler or carrier materials include, but are not limited to, various salts of sulfate, carbonate and silicate as well as talc, clay and the like. Suitable filler or carrier materials for liquid compositions include, but are not limited to water or low molecular weight primary and secondary alcohols including polyols and diols. Examples of such alcohols include, but are not limited to, methanol, ethanol, propanol and isopropanol. In some embodiments, the compositions contain from about 5% to about 90% of such materials. Acidic fillers find use to reduce pH. Alternatively, in some embodiments, the cleaning additive includes adjunct ingredients, as more fully described below.

The present cleaning compositions and cleaning additives require an effective amount of at least one of the lipolytic enzyme variants provided herein, alone or in combination with other lipolytic enzymes and/or additional enzymes. The required level of enzyme is achieved by the addition of one or more lipolytic enzyme variants of the present invention. Typically the present cleaning compositions comprise at least about 0.0001 weight percent, from about 0.0001 to about 10, from about 0.001 to about 1, or even from about 0.01 to about 0.1 weight percent of at least one of the variant lipolytic enzymes of the present invention.

The cleaning compositions herein are typically formulated such that, during use in aqueous cleaning operations, the wash water will have a pH of from about 5.0 to about 11.5, or about 6.0 to 8.0 or even from about 7.5 to about 10.5. Liquid product formulations are typically formulated to have a neat pH from about 3.0 to about 9.0 or even from about 3 to about 8. Granular laundry products are typically formulated to have a pH from about 6 to about 11, or even from about 8 to about 10. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art.

Suitable "low pH cleaning compositions" typically have a neat pH of from about 3 to about 8, and are typically free of surfactants that hydrolyze in such a pH environment. Such surfactants include sodium alkyl sulfate surfactants that comprise at least one ethylene oxide moiety or even from about 1 to about 16 moles of ethylene oxide. Such cleaning compositions typically comprise a sufficient amount of a pH modifier, such as sodium hydroxide, monoethanolamine or hydrochloric acid, to provide such cleaning composition with a neat pH of from about 3 to about 8. Such compositions typically comprise at least one acid stable enzyme. In some embodiments, the compositions are liquids, while in other embodiments, they are solids. The pH of such liquid compositions is typically measured as a neat pH. The pH of such solid compositions is measured as a 10% solids solution of said composition wherein the solvent is distilled water. In these embodiments, all pH measurements are taken at 20^°C, unless otherwise indicated.

In some embodiments, when the variant lipolytic enzyme(s) is/are employed in a granular composition or liquid, it is desirable for the variant lipolytic enzyme to be in the form of an encapsulated particle to protect the variant lipolytic enzyme from other components of the granular composition during storage. In addition, encapsulation is also a means of controlling the availability of the variant lipolytic enzyme during the cleaning process. In some embodiments, encapsulation enhances the performance of the variant lipolytic enzyme(s) and/or additional enzymes. In this regard, the variant lipolytic enzymes of the present invention are encapsulated with any suitable encapsulating material known in the art. In some embodiments, the encapsulating material typically encapsulates at least part of the catalyst for the variant lipolytic enzyme(s) of the present invention. Typically, the encapsulating material is water-soluble and/or water-dispersible. In some embodiments, the encapsulating material has a glass transition temperature (Tg) of 0°C or higher. Glass transition temperature is described in more detail in WO 97/11151. The encapsulating material is typically selected from consisting of carbohydrates, natural or synthetic gums, chitin, chitosan, cellulose and cellulose derivatives, silicates, phosphates, borates, polyvinyl alcohol, polyethylene glycol, paraffin waxes, and combinations thereof. When the encapsulating material is a carbohydrate, it is typically selected from monosaccharides, oligosaccharides, polysaccharides, and combinations thereof. In some typical embodiments, the encapsulating material is a starch (See e.g., EP 0 922 499; US 4,977,252; US 5,354,559, and US 5,935,826). In some embodiments, the encapsulating material is a microsphere made from plastic such as thermoplastics, acrylonitrile, methacrylonitrile, poly acrylonitrile, polymethacrylonitrile and mixtures thereof; commercially available microspheres that find use include, but are not limited to those supplied by EXPANCEL®

(Stockviksverken, Sweden), and PM 6545, PM 6550, PM 7220, PM 7228, EXTENDOSPHERES®, LUXSIL®, Q-CEL®, and SPHERICEL® (PQ Corp., Valley Forge, PA).

As described herein, the variant lipolytic enzymes of the present invention find particular use in the cleaning industry, including, but not limited to laundry and dish detergents. These applications place enzymes under various environmental stresses. The variant lipolytic enzymes of the present invention provide advantages over many currently used enzymes, due to their stability under various conditions.

Indeed, there are a variety of wash conditions including varying detergent formulations, wash water volumes, wash water temperatures, and lengths of wash time, to which lipolytic enzymes involved in washing are exposed. In addition, detergent formulations used in different geographical areas have different concentrations of their relevant components present in the wash water. For example, European detergents typically have about 4500-5000 ppm of detergent components in the wash water, while Japanese detergents typically have approximately 667 ppm of detergent components in the wash water. In North America, particularly the United States, detergents typically have about 975 ppm of detergent components present in the wash water.

A low detergent concentration system includes detergents where less than about 800 ppm of the detergent components are present in the wash water. Japanese detergents are typically considered low detergent concentration system as they have approximately 667 ppm of detergent components present in the wash water.

A medium detergent concentration includes detergents where between about 800 ppm and about 2000ppm of the detergent components are present in the wash water. North American detergents are generally considered to be medium detergent concentration systems as they have approximately 975 ppm of detergent components present in the wash water. Brazil typically has approximately 1500 ppm of detergent components present in the wash water.

A high detergent concentration system includes detergents where greater than about 2000 ppm of the detergent components are present in the wash water. European detergents are generally considered to be high detergent concentration systems as they have approximately 4500-5000 ppm of detergent components in the wash water. Latin American detergents are generally high suds phosphate builder detergents and the range of detergents used in Latin America can fall in both the medium and high detergent concentrations as they range from 1500 ppm to 6000 ppm of detergent components in the wash water. As mentioned above, Brazil typically has approximately 1500 ppm of detergent components present in the wash water.

However, other high suds phosphate builder detergent geographies, not limited to other Latin American countries, may have high detergent concentration systems up to about 6000 ppm of detergent components present in the wash water.

In light of the foregoing, it is evident that concentrations of detergent compositions in typical wash solutions throughout the world varies from less than about 800 ppm of detergent composition ("low detergent concentration geographies"), for example about 667 ppm in Japan, to between about 800 ppm to about 2000 ppm ("medium detergent concentration geographies" ), for example about 975 ppm in U.S. and about 1500 ppm in Brazil, to greater than about 2000 ppm ("high detergent concentration geographies"), for example about 4500 ppm to about 5000 ppm in Europe and about 6000 ppm in high suds phosphate builder geographies.

The concentrations of the typical wash solutions are determined empirically. For example, in the

U.S., a typical washing machine holds a volume of about 64.4 L of wash solution. Accordingly, in order to obtain a concentration of about 975 ppm of detergent within the wash solution about 62.79 g of detergent composition must be added to the 64.4 L of wash solution. This amount is the typical amount measured into the wash water by the consumer using the measuring cup provided with the detergent.

As a further example, different geographies use different wash temperatures. The temperature of the wash water in Japan is typically less than that used in Europe. For example, the temperature of the wash water in North America and Japan is typically between about 10 and about 30^°C (e.g., about 20^°C), whereas the temperature of wash water in Europe is typically between about 30 and about 60^°C (e.g., about 40^°C). However, in the interest of saving energy, many consumers are switching to using cold water washing. In addition, in some further regions, cold water is typically used for laundry, as well as dish washing applications. In some embodiments, the "cold water washing" of the present invention utilizes "cold water detergent" suitable for washing at temperatures from about 10°C to about 40°C, or from about 20°C to about 30°C, or from about 15°C to about 25°C, as well as all other combinations within the range of about 15°C to about 35°C, and all ranges within 10°C to 40°C.

As a further example, different geographies typically have different water hardness. Water hardness is usually described in terms of the grains per gallon mixed Ca²⁺/Mg²⁺. Hardness is a measure of the amount of calcium (Ca²⁺) and magnesium (Mg²⁺) in the water. Most water in the United States is hard, but the degree of hardness varies. Moderately hard (60-120 ppm) to hard (121-181 ppm) water has 60 to 181 parts per million (parts per million converted to grains per U.S. gallon is ppm # divided by 17.1 equals grains per gallon) of hardness minerals. Water Grains per gallon Parts per million

Soft less than 1.0 less than 17

Slightly hard 1.0 to 3.5 17 to 60

Moderately hard 3.5 to 7.0 60 to 120

For North American (NA) and Western European (WE) heavy duty liquid laundry (HDL) detergents, heat inactivation of the enzymes present in commercially-available detergents is performed by placing pre -weighed liquid detergent (in a glass bottle) in a water bath at 95°C for 2 hours. The incubation time for heat inactivation of NA and WE auto dish washing (ADW) detergents is 8 hours. Both un-heated and heated detergents are assayed within 5 minutes of dissolving the detergent to accurately determine percentage deactivated. Enzyme activity is tested by the AAPF assay.

For testing of enzyme activity in heat-inactivated detergents, working solutions of detergents are made from the heat inactivated stocks. Appropriate amounts of water hardness (e.g., 6 gpg or 12 gpg) and buffer are added to the detergent solutions to match the desired conditions. The solutions are mixed by vortexing or inverting the bottles. The following Table provides information regarding some of the commercially-available detergents and test conditions used herein. In some experiments, additional and/or other commercially available detergents find use in the following Examples. Table A. Laundry and Dish Washing Conditions

EXAMPLE 1

Assays

The following assays are standard assays used in the examples described below. Occasionally specific protocols call for deviations from these standard assays. In those cases, deviations from these standard assay protocols below are identified in the examples. A. Performance Index

The performance index (PI) compares the performance of the variant (measured value) and the standard enzyme (theoretical value) at the same protein concentration. In addition, the theoretical values can be calculated, using the parameters of the Langmuir equation of the standard enzyme.

A performance index (PI) that is greater than 1 (PI>1) indicates improved performance by a variant as compared to the standard (e.g., TfuLip2), while a PI of 1 (PI=1) identifies a variant that performs the same as the standard, and a PI that is less than 1 (PI<1) identifies a variant that performs worse than the standard.

B. Hydrolysis of /7-Nitrophenyl Esters

The TfuLip2 variants are assayed for lipase activity on three different para-nitrophenyl (pNP) ester substrates with varying ester chain lengths to determine the chain length preference of TfuLip2 variants. Table 1-1 provides details of the pNP ester substrates. Table 1-1 pNP Ester Substrates

Substrate Abbr Chain-length Source

p-nitrophenyl butyrate pNB C4:0 Sigma (CAS 2635-84-9)

p-nitrophenyl caprylate pNO C8:0 Fluka (CAS 1956-10-1)

(octanoate)

p-nitrophenyl palmitate pNP C16:0 Sigma (CAS 1492-30-4)

A reaction emulsion with pNP ester substrates is prepared using 1.0 mM pNP ester pre- suspended in ethanol (5%) in 0.05 M HEPES, 120 ppm Ca:Mg 2: 1, adjusted to pH 8.2. To aid in the emulsification of the pNP-esters, 0.15% Triton X-100 is added to the buffer.

The pNP-ester/buffer suspensions are mixed and transferred to 96-well microtiter plate wells containing enzyme sample in a total volume of 200 μΕ. Dilution of the enzyme samples and their transfer volumes are adjusted to keep the reaction within a linear range. The generation of liberated pNP is monitored over a period of 4 minutes at OD₄₀5 nm and corrected using blank values (no enzyme). The pNP product generated per second is calculated using a pnp standard curve and then normalized to the added enzyme sample in the well (μηιοΐ pNP/s per added mg enzyme).

The performance index for hydrolysis is determined by comparing the hydrolysis of the variant enzyme on a particular pNP ester substrate with that of the T. fusca TfuLip2 enzyme having the amino acid sequence of SEQ ID NO:3. In all cases the enzyme dosage range being 0.17-12 ppm

C. Detergent Stability

Accelerated detergent stability of the TfuLip2 variants is monitored by stressing the variants in a 10% (w/v) solution of the high density liquid (HDL) detergent known commercially as Omo Lille & Kraftfuld Sensitive (Unilever, Denmark) at elevated temperature.

50 of the detergent/lipase mixture is transferred to 96-well plate wells containing 50 μΕ 10% (w/v) solution of Omo Lille & Kraftfuld. Following mixing, 2.5 μί is transferred to 96 well plate wells containing 197.5 μί pNP octanoate substrate and activity is measured as described in A.

The PCR plate is sealed and incubated in a PCR machine for 30 min at 67.2°C. After end incubation the plate is cooled at room temp for 5 min prior to measuring activity. Activity of the variant enzymes is determined by transferring 2.5ul of the incubated mixtures to a 96 well plate containing 197.5ul of pNP octanoate/buffer suspension, and activity is measured as described in the pNP hydrolysis assay above.

The performance index for detergent stability is determined by comparing the activity ratio of stressed vs unstressed of the variant enzyme with that of the T. fusca TfuLip2 enzyme having the amino acid sequence of SEQ ID NO:3. In all cases the enzyme dosage range being 0.07-0.58 ppm D. Thermostability

Accelerated thermostability of the TfuLip2 variants is monitored by stressing the variants in 50 mM HEPES, pH 8.2 at elevated temperature.

90 μΕ of 50 mM HEPES, pH 8.2 is transferred to 96-well PCR plate wells containing 10 μΕ of the enzyme sample. Following mixing, activity of the variant enzymes is determined by transferring 5ul of the detergent/lipase mixtures to a 96 well plate containing 195ul of pNP octanoate/buffer suspension, and activity is measured as described in the pNP hydrolysis assay above.

The PCR plate is sealed and incubated in a PCR machine for 30 min at 68.7°C. After incubation the plate is cooled at room temp for 5 min prior to measuring activity. Activity of the variant enzymes is determined by transferring lOul of the incubated mixtures to a 96 well plate containing 190ul of pNP octanoate/buffer suspension, activity is measured as described in the pNP hydrolysis assay above.

A thermostability activity ratio is calculated based on enzyme activity after heating, divided by enzyme activity before heating, and is expressed as percentage remaining activity.

The performance index for thermostability is determined by comparing the activity ratio of the variant enzyme, with that of the similarly treated T. fusca TfuLip2 enzyme having the amino acid sequence of SEQ ID NO:3. In all cases the enzyme dosage range being 0.27-2.3 ppm.

E. CS-61 Microswatch Assay

Cleaning performance of the lipase variants is tested in a microswatch assay. Prestained cotton swatches, beef fat with a red dye, CS-61 (Center for Testmaterial, CFT, the Netherlands) are used in a 96-well plate format. Swatches are cut into 5mm diameter pieces and placed in each well of the plate. The performance of the lipase variants are tested in two detergent backgrounds, Omo Lille & Kraftfuld Sensitive (HDL) and Omo Color Traditional (HDD), with a final concentration of 0.6g/L.

Samples of lipase variants to be tested are obtained from filtered culture broth of cultures grown in MTP plates. The buffers used are 20 mM HEPES (final concentration) pH 8.2 for testing Omo Lillle & Kraftfuld, and 20 mM CAPS (final concentration) pH 10.0 for testing Omo Color Traditional. Water hardness is adjusted to 120ppm 2: 1 Ca:Mg for both buffers.

For the HDL detergent 241.5 μΐ and for the HDD detergent 247.5 μΐ of the appropriate buffer described above is added to each swatch-containing well of the 96-well plate. To initiate the reaction, enzyme samples are added at a volume of 8.5 μί for liquid detergent and 2.5 μί for powder detergent into each well. The plates are sealed and shaken for 30 minutes at 900 rpm at 30°C in an iEMS shaker (Thermo scientific). After incubation, the fabrics are rinsed 3 times with de-ionized water using a Hydrospeed plate washer (Tecan, Austria) and dried at 50°C over night. Stain removal is quantified using RGB measurements taken with a scanner (MiCrotek Scan Maker 900), images are imported into Photoshop CSII where RGB values are extracted from the swatch containing areas using IPTK 5.0 from Reindeer Graphics. Percent Soil removal (SRI) values of the washed fabric are calculated in relation to the unwashed fabrics using the formula:

% Soil Removal (SRI)= (AE/AE_iniUal)*100

Where ΔΕ - l (R_after ^~ ^before) + ( after ^~ G before) + ^' 'after ^{~ '} ^before)

Where ΔΕ_{ίηίί:ία}; - \ {R_white ^before) + {^white ^before) + {β white ^before)

The performance index for cleaning performance is calculated by comparing the SRI of the variant enzyme with the SRI of the T. fusca TfuLip2 enzyme having the amino acid sequence of SEQ ID NO:3, at the same enzyme dose as the variant. A Langmuir fit is used to calculate what the SRI for the TfuLip2 would be at the same enzyme dose as the variant. In all cases the enzyme dosage range being 1.0-16 ppm.

F. Detergents

Two commercially available detergents are used:

Omo Lille & Kraftfuld Sensitive (Liquid HDL), Unilever, Denmark. Purchased commercially November 2010

Omo Color Traditional (powder HDD), Unilever, Denmark. Purchased commercially July 2010.

G. Protein Determination

Protein determination of TfuLip2 variants from culture supernatants is performed using an Agilent 1100 HPLC system. A calibration curve (10ppm-400ppm) using purified TfuLip2 protein (concentration determined using A280 absorbance) is prepared in dilution buffer (lOmM sodium phosphate buffer, 10% sodium chloride, 5% acetonitrile, pH 7). TfuLip2 variants are diluted 10-fold in the dilution buffer. All dilutions are made in 96-well microtiter plates. The samples are loaded using an auto-sampler onto a reverse phase, Swift Monolithic RP-all 50mmX4.6mm column (Isco, Lincoln, Nebraska). The samples are eluted from the column using a gradient of Buffer A (0.1% Trifluoroacetic acid) and Buffer B (0.07% Acetonitrile). The flow rate is 1.4mL/min with a 4.5min run and l.Omin post run equilibration. The gradient is as follows:

The absorption of the samples is measured at 222nm using a Spectrophotometer and the prot concentration determined based on the calibration curve. The performance index is determined by comparing the expression of the variant enzyme with that of the T. fusca TfuLip2 enzyme having the amino acid sequence of SEQ ID NO:3.

EXAMPLE 2

Generation of Thermobifida fusca lipase2 (TfuLip2) Site Evaluation Libraries ("SELs") The Thermobifida fusca lipase 2 (or BTA-hydrolase 2) gene was previously identified (Lykidis et al , J. Bacteriol, (2007) 189:2477-2486), with the sequence set forth as GENBANK Accession No.

YP_288944.

The Thermobifida fusca lipase 2 (TfuLip2) gene was synthesized at BaseClear BV (Leiden, The Netherlands) and they cloned into their standard E. coli vector. The TfuLip2 gene was then sub-cloned into the pBN based Bacillus expression vector already containing the aprE promoter and aprE signal sequence (Babe' et al. (1998), Biotechnol. Appl. Biochem. 27: 117-124). Ligation of this vector to the synthetic gene encoding a TfuLip2 enzyme resulted in the fusion of the N-terminus of the TfuLip2 polypeptide to the third amino acid of the Bacillus subtilis AprE pro-peptide encoded by the expression vector. Following the natural signal peptidase cleavage in the host, the recombinant TfuLip2 protein produced in this manner has three additional amino acids (Ala-Gly-Lys) at its amino-terminus. The predicted signal cleavage site was determined by the Signal P 3.0 program

(http://www.cbs.dtu.dk/services/SignalP/), set to SignalP-NN system, (Emanuelsson et al., Nature Protocols (2007), 2: 953-971). The resulting expression vector containing TfuLip2 was named pBN- TfuIII. A map of pBN-TfuIII is shown in Figure 1.

The pBN-TfuIII plasmid containing the Thermobifida fusca lipase2 (TfuLip2) protein encoding sequence (SEQ ID NO: 1) was sent to BaseClear BV for the generation of Site Evaluation Libraries (SELs). The amino acid sequence of the mature TfuLip2 protein is shown in SEQ ID NO: 4. The amino acid sequence of the mature TfuLip2 protein with a three amino acid amino-terminal extension is shown in SEQ ID NO: 3. BaseClear BV generated positional libraries at each of the sites in the TfuLip2 mature protein.

Production of TfuLip2 Variants

The positional library for each of the 261 residues constructed by BaseClear contained approximately 16 amino acid substitution variants. The libraries consisted of transformed B. subtilis cells containing expression plasmids encoding TfuLip2 variant sequences at the 261 positions described. Each variant was confirmed by DNA sequencing analysis prior to protein activity evaluation. Individual clones were cultured as described below to obtain the different TfuLip2 variants for functional characterization. BaseClear BV provided the libraries as 96 well plates, one variant per well, containing cultures frozen in glycerol. Protein Expression

The B. subtilis transformants containing TfuLip2 substitution variants were cultured in 96 well plates for 16 hours in Tryptic Soy Broth (TSB) with 10 μg/ml neomycin, and 10 μΐ of this pre-culture was added to Corning 3599 MTP's filled with 190 ul of cultivation media (described below) supplemented with 10 ug/ml Neomycin. The plates were incubated for 60-65 hours at 37°C at 80% humidity with constant rotational mixing at 300 rpm. Cells were harvested by centriiugation at 2500 rpm for 10 minutes and filtered through Millipore Multiscreen filterplate using a Millipore vacuum system. The culture supernatants were used for assays. The cultivation media was an enriched semi-defined media based on MOPs buffer, with urea as major nitrogen source, glucose as the main carbon source, and supplemented with 1% soytone for robust cell growth.

EXAMPLE 3

Productive Positions and Combinable Mutations

Productive positions are described as those positions within a molecule that are most useful for making combinatorial variants exhibiting an improved characteristic, where the position itself allows for at least one combinable mutation. Combinable mutations can be described as those substitutions in a molecule that can be used to make combinatorial variants. Combinable mutations are ones that improve at least one desired property of the molecule, while not significantly decreasing either: expression, activity, or stability.

Combinable mutations are ones that improve at least one desired property of the molecule, while not significantly decreasing either: expression, activity, or stability. Combinable mutations in Tfulip2 were determined using performance index (PI) values resulting from the assays described in Example 1 : CS-61 micro-swatch assay, hydrolysis of p-Nitrophenyl esters, detergent stability and thermostability assays, and protein determination (expression).

Combinable mutations have been grouped according to the following criteria:

A variant where the minimum performance indices (PI) relative to Tfulip2 parent for expression,

CS-61 micro-swatch activity at pH 8 or pHIO, activity on PNO substrate at pH8 or pHIO, and detergent stability or thermostability are greater than or equal to 0.9, and in in addition have a PI for any one of these tests that is greater than or equal to 1.0 (Group A).

A variant where the minimum performance indices (PI) relative to Tfulip2 parent for expression, CS-61 micro-swatch activity at pH 8 or pHIO, activity on PNO substrate at pH8 or pHIO, and detergent stability or thermostability are greater than or equal to 0.8, and in in addition have a PI for any one of these tests that is greater than or equal to 1.2 (Group B).

A variant where the minimum performance indices (PI) relative to Tfulip2 parent for expression, CS-61 micro-swatch activity at pH 8 or pHIO, activity on PNO substrate at pH8 or pHIO, and detergent stability or thermostability are greater than or equal to 0.5, and in in addition have a PI for any one of these tests that is greater than or equal to 1.5 (Group C). Groups A, B, and C further contain amino acid positions that have differing degrees of tolerance for multiple substitutions. To identify productive positions, we measure the degree of substitutions tolerated at each position and assign a Productivity Score to each position. The Productivity Score was assigned according to the percentage of substitutions within each position that fall within groups A, B, or C, using the criteria set forth below.

Productive positions are defined as the positions which have shown a certain degree of tolerance for multiple substitutions, while at the same time meeting a set of criteria for combinability as set forth below.

The criteria to determine the Productivity Score for productive positions are as follows:

Positions where less than 15% of the substitutions at a given position fall within groups A, B, or

C are given a Productivity Score of "1". (Table 3.4)

Positions where less than 40%, but greater than, or equal to 15% of the substitutions at a given position fall within groups A, B, or C are given a Productivity Score of "2". (Table 3.3)

Positions where less than 75%, but greater than, or equal to 40% of the substitutions at a given position fall within groups A, B, or C are given a Productivity Score of "3". (Table 3.2)

Positions where 75% or more of the substitutions at a given position fall within groups A, B, or C are given a Productivity Score of "4". (Table 3.1)

Table 3.1 shows the productive positions in TfuLip2 that fall within the previously described

Productivity Score of "4" and the substitutions within those positions that are combinable. Position numbering based on mature TfuLip2 listed in SEQ ID NO: 4.

EXAMPLE 4

Combinable Mutations and Suitability Scores

As shown in Example 3, combinable mutations in Tfulip2 were determined using performance index (PI) values resulting from the assays described in Example 1 : CS-61 micro-swatch assay, hydrolysis of p-Nitrophenyl esters, (activity), detergent stability and thermostability assays, and protein determination (expression).

Combinable mutations were assigned to groups A, B or C according to criteria set forth in Example 3. These substitutions are further assigned a Suitability Score based on the group(s) (A, B, C) where the substitution appears, and where a higher suitability score represents a substitution more suitable for use in making combinatorial variants. Suitability scores are defined in Table 4.1. Suitability scores for individual substitutions of Tfulilp2 that fit the above criteria are reported in Table 4.2.

Table 4.1 defines each Suitability Score as it relates to groups of combinable mutations and productive positions.

Surface Modifications

Positions and substitutions contributing to favorable surface modifications, such as altered charge or hydrophobicity of TfuLip2, are set forth in Table 5.1. Productive positions containing all combinable substitutions were determined using the criteria for productive positions as described in Example 3. The data were further analyzed to determine substitutions which change hydrophobicity or charge, and maintain all important properties. Hydrophobicity of each substitution was determined using the methods of White and Wimley (White,S.H. and Wimley, W.C,. Annu. Rev. Biophys. Biomol. Struct. 28:319-65 (1999.). A subgroup of combinable positions and substitutions demonstrating favorable surface modifications in TfuLip2 is shown in Table 5.1.

Comparison of TfuLip2 to Related Molecules

A. Identification of Related Molecules by Sequence Analysis.

Homologs were obtained by BLAST search (Altschul SF, Madden TL, Schaffer AA, Zhang J, Zhang Z, Miller W, Lipman DJ.1997). Gapped BLAST and PSI-BLAST: a new generation of protein database search programs. Nucleic Acids Res. 25:3389-402) against the NCBI non-redundant protein database, nr, using the mature protein amino acid sequence for TfuLip2 as the query sequence. Only sequences which have percent identity of 50% or higher were retained. Percent identity (PID) is defined as the number of identical residues divided by the number of aligned residues in the pairwise alignment. Table 6.1 provides the list of sequences which have percent identity of 50% or higher to TfuLip2. The table provides accession numbers to each identified homolog; the identified organism, the length (number of amino acids) of each protein sequence; and the PID (percent identity).

B. Alignment of Sequences for Homologous Molecules.

The sequences of TfuLip2 and selected homologs were multiply aligned with CLUSTALW software (Thompson, J.D., Higgins, D.G. and Gibson, T.J. (1994) CLUSTAL W: improving the sensitivity of progressive multiple sequence alignment through sequence weighting, positions-specific gap penalties and weight matrix choice. Nucleic Acids Research, 22:4673-4680) using default parameters and refined with MUSCLE (Multiple Sequence Comparison by Log- Expectation; MUSCLE: multiple sequence alignment with high accuracy and high throughput. Robert Edgar 2004. Nucl. Acids Res. 32: 1792-1797) using default parameters. For homologous sequences, only regions that correspond to seed sequences are shown. Redundant sequences that are 98% or higher in PID are not included in further analysis. Figure 2A-G shows the alignment of TfuLip2 and homolog sequences.

C. Phylogenetic Tree

A Phylogenetic tree was built for TfuLip2 and its homologs with the Neighbor-Joining algorithm using ClustalW software with 10000 bootstraps based on the refined alignments described above in section B. Bootstrapping was used to assess the reliability of the tree branches (Felsenstein J (1985) Confidence limits on phylogenies: An approach using the bootstrap. Evolution 39:783-791). Other ClustalW parameters were the default values. The phylogenetic tree was rendered by the program Phylo Widget (Phylo Widget: web-based visualizations for the tree of life Gregory E. Jordan; William H. Piel Bioinformatics 2008 24: 1641-1642 http://www.phylowidget.org/) Figure 3 shows the phylogenetic tree built for TfuLip2.
