CLEANING COMPOSITIONS CONTAINING DISPERSINS I

Background of the Invention Field of the Invention

The present invention relates to specific cleaning compositions comprising polypeptides having hexosaminidase activity. The invention further relates to the use of said compositions as well as methods of using said compositions. Description of the Related Art

Polypeptides having hexosaminidase activity include Dispersins such as Dispersin B (DspB) which is β-Ν-acetylglucosamininidases belonging to the Glycoside Hydrolase 20 family. Dispersins are produced by the periodontal pathogen, Aggregatibacter actinomycetemcomitans, a Gram-negative oral bacterium. Dispersin B is a β-hexosaminidase that specifically hydrolyzes -1 ,6-glycosidic linkages of acetylglucosamine polymers found in biofilm. Dispersin B contains three highly conserved acidic residues: an aspartic acid at residue 183 (D183), a glutamic acid at residue 184 (E184), and a glutamic acid at residue 332 (E332). Biofilm have been found attached to various surfaces including medical devices such as implants. WO04061117 A2 (Kane Biotech INC) describes use of compositions comprising DspB for reducing biofilm caused by poly-N-acetylglucosamine-producing bacteria and Kane et al. describe the use of compositions comprising DspB for reduction of biofilm on medical devises and for wound care. Biofilm may also be present on laundry items, such as fabrics, other hard surfaces, such as dish wash utensils, dish washers and washing machines where they may cause malodor, which is difficult to remove even after wash. Biofilm may also make laundry items sticky and soil may adhere to the sticky areas. The present invention provides compositions which comprise suitable enzymes as described herein for use in detergents and for deep cleaning in laundry and cleaning processes.

Allelic variant: The term "allelic variant" means any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.

Biofilm: A biofilm may be produced by any group of microorganisms in which cells stick to each other or stick to a surface, such as a textile, dishware or hard surface or another kind of surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium. Bacteria living in a biofilm usually have significantly different properties from planktonic bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One benefit of this environment for the microorganisms is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community. On laundry and hard surfaces biofilm producing bacteria can be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp Micrococcus luteus, Pseudomonas sp., Streptococcus sp., Streptococcus dysgalactiae, Staphylococcus epidermidis, Staphylococcus aureus, Staphylococcus pneumoniae, Stenotrophomonas sp., Enterobacter sp., Xanthomonas sp., Yersinia sp., Klebsiella sp., Burkholderia sp., Stenotrophomonas sp., Variovorax sp., Escherichia sp., Ralston ia sp., Achromobacter sp., Luteibacter sp., Citrobacter sp., Xanthomonadaceae sp., Halomonas sp., Bordetella sp., Lysobacter sp., Serratia sp., Escherichia sp., Aggregatibacter sp., Listeria monocytogenes, Clostridium difficile, Mycobacterium sp., Neisseria gonorrheae, H. influenzae, Haemophilus ducreyi, Helicobacter pylori, Campylobacter jejuni and Enterococcus faecalis as well as the fungi Candida albicans, Aspergillus flavus, Fusarium solani, and Cryptococcus neoformans. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Brevundimonas sp. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Pseudomonas alcaliphila or Pseudomonas fluoresceins. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Staphylococcus aureus.

Catalytic domain: The term "catalytic domain" means the region of an enzyme containing the catalytic machinery of the enzyme.

cDNA: The term "cDNA" means a DNA molecule that can be prepared by reverse transcription from a mature, spliced, mRNA molecule obtained from a eukaryotic or prokaryotic cell. cDNA lacks intron sequences that may be present in the corresponding genomic DNA. The initial, primary RNA transcript is a precursor to mRNA that is processed through a series of steps, including splicing, before appearing as mature spliced mRNA.

Clade: a group of polypeptides clustered together on the basis of homologous features traced to a common ancestor. Polypeptide clades can be visualized as phylogenetic trees and a clade is a group of polypeptides that consists of a common ancestor and all its lineal descendants (Figure 1 ). The polypeptides of the invention all belong to the DspB clade, which is illustrated as a phylogenetic tree in figure 1. The clade of DspB or the DspB clade is a group of enzymes all related to the same ancestor and share common properties. Polypeptides forming a group within the clade (a subclade) of the phylogenetic tree can also share common properties and are more closely related than other polypeptides in the clade.

Coding sequence: The term "coding sequence" means a polynucleotide, which directly specifies the amino acid sequence of a polypeptide. The boundaries of the coding sequence are generally determined by an open reading frame, which begins with a start codon such as ATG, GTG, or TTG and ends with a stop codon such as TAA, TAG, or TGA. The coding sequence may be a genomic DNA, cDNA, synthetic DNA, or a combination thereof.

Control sequences: The term "control sequences" means nucleic acid sequences necessary for expression of a polynucleotide encoding a mature polypeptide of the present invention. Each control sequence may be native (i.e., from the same gene) or foreign (i.e., from a different gene) to the polynucleotide encoding the polypeptide or native or foreign to each other. Such control sequences include, but are not limited to, a leader, polyadenylation sequence, propeptide sequence, promoter, signal peptide sequence, and transcription terminator. At a minimum, the control sequences include a promoter, and transcriptional and translational stop signals. The control sequences may be provided with linkers for the purpose of introducing specific restriction sites facilitating ligation of the control sequences with the coding region of the polynucleotide encoding a polypeptide.

Deep cleaning: By the term "deep cleaning" is meant reduction or removal of components of biofilm, such as EPS or parts hereof, polysaccharides, poly-N-acetylglucosamine (PNAG), proteins, DNA, soil or other components present in the biofilm.

Detergent (e.g. cleaning) adjunct ingredient: The detergent adjunct ingredient is different to the hexosaminidase of this invention. The precise nature of these additional adjunct components, and levels of incorporation thereof, will depend on the physical form of the composition and the nature of the operation for which it is to be used. Suitable adjunct materials include, but are not limited to the components described below such as surfactants, builders, flocculating aid, chelating agents, dye transfer inhibitors, enzymes, enzyme stabilizers, enzyme inhibitors, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, fabric softeners, carriers, hydrotropes, builders and co-builders, fabric huing agents, anti-foaming agents, dispersants, processing aids, bittering agents, and/or pigments. Cleaning and/or Detergent Composition: The terms "cleaning composition" and "detergent composition" are used interchangeably herein and refer to compositions that find use in the removal of undesired compounds from items to be cleaned, such as textiles or hard surfaces. The detergent composition may be used to e.g. clean textiles for both household cleaning and industrial cleaning. The terms encompass any materials/compounds selected for the particular type of cleaning composition desired and the form of the product (e.g., liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions (e.g., liquid and/or solid laundry detergents and fine fabric detergents; fabric fresheners; fabric softeners (fabric finishers); and textile and laundry pre-spotters/pretreatment). In addition, the term also includes hand and automatic dishwashing detergents and cleaning detergents for hard surfaces. In addition to containing the enzyme as defined herein, the detergent formulation may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidases, haloperoxygenases, catalases and mannanases, or any mixture thereof), and/or detergent adjunct ingredients such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anti-corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.

Enzyme Detergency benefit: The term "enzyme detergency benefit" is defined herein as the advantageous effect an enzyme may add to a detergent compared to the same detergent without the enzyme. Important detergency benefits which can be provided by enzymes are stain removal with no or very little visible soils after washing and/or cleaning, prevention or reduction of redeposition of soils released in the washing process (an effect that also is termed anti-redeposition), restoring fully or partly the whiteness of textiles which originally were white but after repeated use and wash have obtained a greyish or yellowish appearance (an effect that also is termed whitening). Textile care benefits, which are not directly related to catalytic stain removal or prevention of redeposition of soils, are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one fabric to another fabric or another part of the same fabric (an effect that is also termed dye transfer inhibition or anti-backstaining), removal of protruding or broken fibers from a fabric surface to decrease pilling tendencies or remove already existing pills or fuzz (an effect that also is termed anti-pilling), improvement of the fabric-softness, colour clarification of the fabric and removal of particulate soils which are trapped in the fibers of the fabric or garment. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching components such as hydrogen peroxide or other peroxides. Expression: The term "expression" includes any step involved in the production of a polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post- translational modification, and secretion.

Expression vector: The term "expression vector" means a linear or circular DNA molecule that comprises a polynucleotide encoding a polypeptide and is operably linked to control sequences that provide for its expression.

Fragment: The term "fragment" means a polypeptide or a catalytic domain having one or more (e.g., several) amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide or domain; wherein the fragment has hexosaminidase activity. In one aspect, a fragment contains at least 304 amino acid residues (e.g. , amino acids 47 to 350 of SEQ ID NO: 2), at least 310 amino acid residues (e.g., amino acids 44 to 353 of SEQ ID NO: 2), or at least 316 amino acid residues (e.g., amino acids 41 to 356 of SEQ ID NO: 2).

The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled "longest identity" (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:

Detailed Description of the Invention

The present invention relates to compositions as defined herein comprising polypeptides having hexosaminidase activity preferably PNAG (poly-N-acetylglucosamine) activity. Organic matter such as biofilm produces EPS (extra polymeric substances), which often comprises polysaccharides such as PNAG. The polypeptides described herein are therefore effective in preventing, reducing and removing organic components such as PNAG. Organic matter such as biofilm associated with cleaning processes e.g. in textiles such as laundry is an important challenge since it may be associated with consumer relevant problems such as e.g. malodor and re-deposition. WO2014/087011 describes the use of a deoxyribonuclease (DNase) and other enzymes for reducing malodor from laundry and/or textile, WO9909143 describes the use of one or more oxidoreductases in combination with a mediator for the reduction of malodor and WO2012/112718 describes a method for inhibiting production of laundry malodor caused by bacteria by using various strains of Bacillus. The present invention relates to cleaning compositions comprising polypeptides from the clade of DspB having hexosaminidase activity. Also claimed are cleaning/laundering methods and the use of the compositions comprising polypeptides with hexosaminidase activity. In particular, the polypeptides from the clade of DspB with hexosaminidase activity are useful in reducing and preventing staining of items being washed. The inventors have surprisingly found that the polypeptides of the clade of DspB having hexosaminidase activity are useful for laundry associated biofilm components, such as EPS and/or PNAG. In WO2004061 17 is described compositions comprising DspB, the composition may include a detergent which may be anionic, cationic, or non-ionic. However, there is no indication in the art of the use of DspB in cleaning processes such as laundry or in detergent compositions comprising e.g. builders and/or bleaches. To be useful in cleaning processes the enzymes need to perform its action in detergents under the conditions of cleaning processes such as laundry, which includes stability in the presence of detergent components such as surfactants, builders and bleach components. Components of a detergent may significantly effect on the performance of the enzymes such as DspB. The present application surprisingly shows that polypeptides belonging to the DspB clades and which have hexosaminidase activity are useful for deep cleaning e.g. of textiles or washing machines.

The polypeptide described herein may comprise several motifs one example is GXDE (SEQ ID NO 27) situated in positions corresponding to positions 166 to 169 in Haemophilus sputorum (SEQ ID NO 18). Residues D and E are the key catalytic residues of GH20 enzymes (position 160 to 161 in SEQ ID NO 9). The polypeptides described herein having hexosaminidase e.g. PNAG activity may comprise the structural domains of GH20. The polypeptides in GH20 can be separated into multiple distinct sub- clusters, or clades, where we denoted the clades listed below. The distinct motifs for each clade are described in details below.

A domain, preferably shared by the polypeptides described herein, was identified. This domain has not been described previously. The domain is termed LES and polypeptides of this domain preferably comprises a GH20 domain, are preferably of bacterial origin and have hexosaminidase activity e.g. PNAG activity.

The polypeptides comprising the LES domain are preferably of bacterial origin, have hexosaminidase e.g. PNAG activity. The polypeptides of the LES domain HFH clade comprises the motif example HFHIGG (SEQ ID NO: 29), corresponding to pos 162 to 167 of SEQ ID NO 18, where H (corresponding to position 162 of SEQ ID NO 18) is fully conserved in HFH clade. Another motif which may be comprised by the polypeptides of the HFH clade is FLHLHF (SEQ ID NO: 30), 37 to 42 in SEQ ID NO 18. A further motif which may be comprised by the polypeptides of the HFH clade is DHENYA (SEQ ID NO: 31 ), corresponding to amino acids 44 to 49 of SEQ ID NO 18.

One embodiment relates to compositions as defined herein comprising polypeptides comprising one or more motif(s) GXDE (SEQ ID NO 27), [EQ][NRSHA][YVFL][AGSTC][IVLF][EAQYN][SN] (SEQ ID NO: 28), HFHIGG (SEQ ID NO: 29), FLHLHF (SEQ ID NO: 30) or DHENYA (SEQ ID NO: 31 ), preferably one or more of the motif(s) HFHIGG (SEQ ID NO: 29), FLHLHF (SEQ ID NO: 30) or DHENYA (SEQ ID NO: 31 ).

In one embodiment, the polypeptide belongs to the HFH clade and comprises one or more motif(s) HFHIGG (SEQ ID NO: 29), FLHLHF (SEQ ID NO: 30) or DHENYA (SEQ ID NO: 31 ).

An overview of the DspB clade is provided in figure 1. The DspB clade comprises homologous sequences close to DspB. The polypeptides with hexosaminidase activity of the present invention having the mature amino acid sequences SEQ ID 17, 18, 19, 20, 21 , 22, 23 and 24 can be pairwise aligned using the Needleman- Wunsch algorithm (Needleman and Wunsch, 1970, J.

In another aspect, the polypeptide comprises or consists of amino acids 1 to 351 of SEQ ID NO: 16.

In another embodiment, the present invention relates to compositions as described herein, comprising a polypeptide having hexosaminidase activity encoded by a polynucleotide that hybridizes under very low stringency conditions, low stringency conditions, medium stringency conditions, medium- high stringency conditions, high stringency conditions, or very high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1 , 3, 5, 7, 9, 1 1 , 13 or 15 or (ii) the full-length complement of (i) (Sambrook et al. , 1989, Molecular Cloning, A Laboratory Manual, 2d edition, Cold Spring Harbor, New York). In an embodiment, the polypeptide has been isolated.

The polynucleotide of SEQ ID NO: 1 , 3, 5, 7, 9, 1 1 , 13 or 15 or a subsequence thereof, as well as the mature polypeptide of SEQ ID NO: 2, 4, 6, 8, 10, 12, 14 or 16 or a fragment thereof may be used to design nucleic acid probes to identify and clone DNA encoding polypeptides having hexosaminidase activity from strains of different genera or species according to methods well known in the art. In particular, such probes can be used for hybridization with the genomic DNA or cDNA of a cell of interest, following standard Southern blotting procedures, in order to identify and isolate the corresponding gene therein. Such probes can be considerably shorter than the entire sequence, but should be at least 15, e.g., at least 25, at least 35, or at least 70 nucleotides in length. Preferably, the nucleic acid probe is at least 100 nucleotides in length, e.g. , at least 200 nucleotides, at least 300 nucleotides, at least 400 nucleotides, at least 500 nucleotides, at least 600 nucleotides, at least 700 nucleotides, at least 800 nucleotides, or at least 900 nucleotides in length. Both DNA and RNA probes can be used. The probes are typically labeled for detecting the corresponding gene (for example, with ³²P, ³H, ³⁵S, biotin, or avidin). Such probes are encompassed by the present invention.

A genomic DNA or cDNA library prepared from such other strains may be screened for DNA that hybridizes with the probes described above and encodes a polypeptide having hexosaminidase activity. Genomic or other DNA from such other strains may be separated by agarose or polyacrylamide gel electrophoresis, or other separation techniques. DNA from the libraries or the separated DNA may be transferred to and immobilized on nitrocellulose or other suitable carrier material. In order to identify a clone or DNA that hybridizes with SEQ ID NO: 1 or a subsequence thereof, the carrier material is used in a Southern blot.

For purposes of the present invention, hybridization indicates that the polynucleotide hybridizes to a labeled nucleic acid probe corresponding to (i) SEQ ID NO: 1 , 3, 5, 7, 9, 1 1 , 13 or 15; (ii) the mature polypeptide coding sequence of SEQ ID NO: 1 , 3, 5, 7, 9, 11 , 13 or 15; (iii) the full-length complement thereof; or (iv) a subsequence thereof; under very low to very high stringency conditions. Molecules to which the nucleic acid probe hybridizes under these conditions can be detected using, for example, X-ray film or any other detection means known in the art.

In a further embodiment, the polypeptide has been isolated. In another embodiment, the present invention relates to compositions as described herein comprising a polypeptide having hexosaminidase activity encoded by a polynucleotide having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 11 of at least 60%, e.g. , at least 65%, 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%, at least 99%, or 100%. In a further embodiment, the polypeptide has been isolated.

In another embodiment, the present invention relates to compositions as described herein comprising a polypeptide having hexosaminidase activity encoded by a polynucleotide having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 13 of at least 60%, e.g. , at least 65%, 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%, at least 99%, or 100%. In a further embodiment, the polypeptide has been isolated.

In another embodiment, the present invention relates to compositions as described herein comprising a polypeptide having hexosaminidase activity encoded by a polynucleotide having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 15 of at least 60%, e.g. , at least 65%, 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%, at least 99%, or 100%. In a further embodiment, the polypeptide has been isolated.

In another embodiment, the present invention relates to compositions as described herein comprising variants of the mature polypeptide of SEQ ID NO: 2, 4, 6, 8, 10, 12, 14 or 16 comprising a substitution, deletion, and/or insertion at one or more (e.g., several) positions. In an embodiment, the number of amino acid substitutions, deletions and/or insertions introduced into the mature polypeptide of SEQ ID NO: 2, 4, 6, 8, 10, 12, 14 or 16 is up to 10, e.g. , 1 , 2, 3, 4, 5, 6, 7, 8, 9, or 10. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R.L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/lle, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/lle, Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that the physico-chemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like. Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant molecules are tested for hexosaminidase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton ef a/., 1996, J. Biol. Chem. 271 : 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos ef a/. , 1992, Science 255: 306-312; Smith ef a/. , 1992, J. Mol. Biol. 224: 899-904; Wlodaver ef a/. , 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide. The polypeptides of the invention belong to the Dispersin B clade. The Dispersin B is a β-hexosaminidase that specifically hydrolyzes β-1 ,6-glycosidic linkages of acetylglucosamine polymers found in e.g. biofilm. Dispersin B contains three highly conserved acidic residues: an aspartic acid at residue 183 (D183), a glutamic acid at residue 184 (E184), and a glutamic acid at residue 332 (E332).

Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241 : 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage Dsplay (e.g. , Lowman ef a/. , 1991 , Biochemistry 30: 10832-10837; U.S. Patent No. 5,223,409; WO 92/06204), and region-directed mutagenesis (Derbyshire ef a/., 1986, Gene 46: 145; Ner ef a/., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness ef a/. , 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.

The polypeptide may be a hybrid polypeptide in which a region of one polypeptide is fused at the N-terminus or the C-terminus of a region of another polypeptide.

The polypeptide may be a fusion polypeptide or cleavable fusion polypeptide in which another polypeptide is fused at the N-terminus or the C-terminus of the polypeptide of the present invention. A fusion polypeptide is produced by fusing a polynucleotide encoding another polypeptide to a polynucleotide of the present invention. Techniques for producing fusion polypeptides are known in the art, and include ligating the coding sequences encoding the polypeptides so that they are in frame and that expression of the fusion polypeptide is under control of the same promoter(s) and terminator. Fusion polypeptides may also be constructed using intein technology in which fusion polypeptides are created post-translationally (Cooper ef a/. , 1993, EMBO J. 12: 2575-2583; Dawson ef a/., 1994, Science 266: 776-779). A fusion polypeptide can further comprise a cleavage site between the two polypeptides. Upon secretion of the fusion protein, the site is cleaved releasing the two polypeptides. Examples of cleavage sites include, but are not limited to, the sites disclosed in Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina ei al., 2000, J. Biotechnol. 76: 245-251 ; Rasmussen-Wilson ei a/., 1997, Appl. Environ. Microbiol. 63: 3488-3493; Ward ef a/. , 1995, Biotechnology 13: 498-503; and Contreras ei a/. , 1991 , Biotechnology 9: 378-381 ; Eaton et al. , 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995, Biotechnology 13: 982-987; Carter ef al., 1989, Proteins: Structure, Function, and Genetics 6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.

For purposes of the present invention, the term "obtained from" as used herein in connection with a given source shall mean that the polypeptide encoded by a polynucleotide is produced by the source or by a strain in which the polynucleotide from the source has been inserted.

It will be understood that for the aforementioned species, the invention encompasses both the perfect and imperfect states, and other taxonomic equivalents, e.g. , anamorphs, regardless of the species name by which they are known. Those skilled in the art will readily recognize the identity of appropriate equivalents.

Strains of these species are readily accessible to the public in a number of culture collections, such as the American Type Culture Collection (ATCC), Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ), Centraalbureau Voor Schimmelcultures (CBS), and Agricultural Research Service Patent Culture Collection, Northern Regional Research Center (NRRL). The polypeptide may be identified and obtained from other sources including microorganisms isolated from nature (e.g., soil, composts, water, etc.) or DNA samples obtained directly from natural materials (e.g., soil, composts, water, etc.) using the above-mentioned probes. Techniques for isolating microorganisms and DNA directly from natural habitats are well known in the art. A polynucleotide encoding the polypeptide may then be obtained by similarly screening a genomic DNA or cDNA library of another microorganism or mixed DNA sample. Once a polynucleotide encoding a polypeptide has been detected with the probe(s), the polynucleotide can be isolated or cloned by utilizing techniques that are known to those of ordinary skill in the art (see, e.g., Sambrook ef a/., 1989, supra).

Nucleic Acid Constructs

The present disclosure also relates to nucleic acid constructs comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.

The polynucleotide may be manipulated in a variety of ways to provide for expression of the polypeptide. Manipulation of the polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.

The control sequence may be a promoter, a polynucleotide that is recognized by a host cell for expression of a polynucleotide encoding a polypeptide of the present invention. The promoter contains transcriptional control sequences that mediate the expression of the polypeptide. The promoter may be any polynucleotide that shows transcriptional activity in the host cell including variant, truncated, and hybrid promoters, and may be obtained from genes encoding extracellular or intracellular polypeptides either homologous or heterologous to the host cell. Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in a bacterial host cell are the promoters obtained from the Bacillus amyloliquefaciens alpha-amylase gene (amyQ), Bacillus licheniformis alpha-amylase gene (amyL), Bacillus licheniformis penicillinase gene (penP), Bacillus stearothermophilus maltogenic amylase gene (amyM), Bacillus subtilis levansucrase gene (sacB), Bacillus subtilis xylA and xylB genes, Bacillus thuringiensis crylllA gene (Agaisse and Lereclus, 1994, Molecular Microbiology 13: 97-107), E. col i lac operon, E. coli trc promoter (Egon ef a/., 1988, Gene 69: 301-315), Streptomyces coelicolor agarase gene (dagA), and prokaryotic beta-lactamase gene (Villa- Kamaroff ef a/. , 1978, Proc. Natl. Acad. Sci. USA 75: 3727-3731 ), as well as the tac promoter (DeBoer ef a/. , 1983, Proc. Natl. Acad. Sci. USA 80: 21-25). Further promoters are described in "Useful proteins from recombinant bacteria" in Gilbert ef a/., 1980, Scientific American 242: 74-94; and in Sambrook ef a/., 1989, supra. Examples of tandem promoters are disclosed in WO 99/43835.

Other promoters are described in U.S. Patent No. 6,01 1 , 147.

In a yeast host, useful promoters are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1 ), Saccharomyces cerevisiae galactokinase (GAL1 ), Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH1 , ADH2/GAP), Saccharomyces cerevisiae triose phosphate isomerase (TPI), Saccharomyces cerevisiae metallothionein (CUP1 ), and Saccharomyces cerevisiae 3-phosphoglycerate kinase. Other useful promoters for yeast host cells are described by Romanos ef a/., 1992, Yeasf 8: 423-488.

The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator is operably linked to the 3'-terminus of the polynucleotide encoding the polypeptide. Any terminator that is functional in the host cell may be used in the present invention.

Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA {rrnB). Preferred terminators for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans acetamidase, Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase, Aspergillus oryzae TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei beta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei cellobiohydrolase II, Trichoderma reesei endoglucanase I, Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase II, Trichoderma reesei xylanase III, Trichoderma reesei beta-xylosidase, and Trichoderma reesei translation elongation factor.

Other useful terminators for yeast host cells are described by Romanos et al. , 1992, supra.

The control sequence may also be an mRNA stabilizer region downstream of a promoter and upstream of the coding sequence of a gene which increases expression of the gene.

Examples of suitable mRNA stabilizer regions are obtained from a Bacillus thuringiensis crylllA gene (WO 94/25612) and a Bacillus subtilis SP82 gene (Hue ef a/. , 1995, Journal of Bacteriology 177: 3465-3471 ).

The control sequence may also be a leader, a nontranslated region of an mRNA that is important for translation by the host cell. The leader is operably linked to the 5'-terminus of the polynucleotide encoding the polypeptide. Any leader that is functional in the host cell may be used.

Preferred leaders for filamentous fungal host cells are obtained from the genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulans triose phosphate isomerase.

Suitable leaders for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1 ), Saccharomyces cerevisiae 3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).

The control sequence may also be a polyadenylation sequence, a sequence operably linked to the 3'-terminus of the polynucleotide and, when transcribed, is recognized by the host cell as a signal to add polyadenosine residues to transcribed mRNA. Any polyadenylation sequence that is functional in the host cell may be used.

Preferred polyadenylation sequences for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-like protease.

Useful polyadenylation sequences for yeast host cells are described by Guo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a polypeptide and directs the polypeptide into the cell's secretory pathway. The 5'-end of the coding sequence of the polynucleotide may inherently contain a signal peptide coding sequence naturally linked in translation reading frame with the segment of the coding sequence that encodes the polypeptide. Alternatively, the 5'-end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required where the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, a foreign signal peptide coding sequence may simply replace the natural signal peptide coding sequence in order to enhance secretion of the polypeptide. However, any signal peptide coding sequence that directs the expressed polypeptide into the secretory pathway of a host cell may be used.

Effective signal peptide coding sequences for bacterial host cells are the signal peptide coding sequences obtained from the genes for Bacillus NCIB 1 1837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral proteases (nprT, nprS, nprM), and Bacillus subtilis prsA. Further signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57: 109-137.

Effective signal peptide coding sequences for filamentous fungal host cells are the signal peptide coding sequences obtained from the genes for Aspergillus niger neutral amylase, Aspergillus niger glucoamylase, Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicola insolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucor miehei aspartic proteinase.

Useful signal peptides for yeast host cells are obtained from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences are described by Romanos et al. , 1992, supra.

The control sequence may also be a propeptide coding sequence that encodes a propeptide positioned at the N-terminus of a polypeptide. The resultant polypeptide is known as a proenzyme or propolypeptide (or a zymogen in some cases). A propolypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. The propeptide coding sequence may be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, the propeptide sequence is positioned next to the N-terminus of a polypeptide and the signal peptide sequence is positioned next to the N-terminus of the propeptide sequence.

It may also be desirable to add regulatory sequences that regulate expression of the polypeptide relative to the growth of the host cell. Examples of regulatory sequences are those that cause expression of the gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GAL1 system may be used. In filamentous fungi, the Aspergillus niger glucoamylase promoter, Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzae glucoamylase promoter, Trichoderma reesei cellobiohydrolase I promoter, and Trichoderma reesei cellobiohydrolase II promoter may be used. Other examples of regulatory sequences are those that allow for gene amplification. In eukaryotic systems, these regulatory sequences include the dihydrofolate reductase gene that is amplified in the presence of methotrexate, and the metallothionein genes that are amplified with heavy metals. In these cases, the polynucleotide encoding the polypeptide would be operably linked to the regulatory sequence. Expression Vectors

The present disclosure also relates to recombinant expression vectors comprising a polynucleotide of the present invention, a promoter, and transcriptional and translational stop signals. The various nucleotide and control sequences may be joined together to produce a recombinant expression vector that may include one or more convenient restriction sites to allow for insertion or substitution of the polynucleotide encoding the polypeptide at such sites. Alternatively, the polynucleotide may be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression. The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and can bring about expression of the polynucleotide. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vector may be a linear or closed circular plasmid. The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g. , a plasmid, an extrachromosomal element, a minichromosome, or an artificial chromosome. The vector may contain any means for assuring self-replication. Alternatively, the vector may be one that, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids that together contain the total DNA to be introduced into the genome of the host cell, or a transposon, may be used.

The vector preferably contains one or more selectable markers that permit easy selection of transformed, transfected, transduced, or the like cells. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis or Bacillus subtilis dal genes, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline resistance. Suitable markers for yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, MET3, TRP1 , and URA3. Selectable markers for use in a filamentous fungal host cell include, but are not limited to, adeA (phosphoribosylaminoimidazole- succinocarboxamide synthase), adeB (phosphoribosyl-aminoimidazole synthase), amdS (acetamidase), argB (ornithine carbamoyltransferase), bar (phosphinothricin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5'-phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), as well as equivalents thereof. Preferred for use in an Aspergillus cell are Aspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and a Streptomyces hygroscopicus bar gene. Preferred for use in a Trichoderma cell are adeA, adeB, amdS, hph, and pyrG genes.

The selectable marker may be a dual selectable marker system as described in WO 2010/039889. In one aspect, the dual selectable marker is an hph-tk dua\ selectable marker system. The vector preferably contains an element(s) that permits integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome.

For integration into the host cell genome, the vector may rely on the polynucleotide's sequence encoding the polypeptide or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides for directing integration by homologous recombination into the genome of the host cell at a precise location(s) in the chromosome(s). To increase the likelihood of integration at a precise location, the integrational elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, which have a high degree of sequence identity to the corresponding target sequence to enhance the probability of homologous recombination. The integrational elements may be any sequence that is homologous with the target sequence in the genome of the host cell. Furthermore, the integrational elements may be non-encoding or encoding polynucleotides. On the other hand, the vector may be integrated into the genome of the host cell by non-homologous recombination.

For autonomous replication, the vector may further comprise an origin of replication enabling the vector to replicate autonomously in the host cell in question. The origin of replication may be any plasmid replicator mediating autonomous replication that functions in a cell. The term "origin of replication" or "plasmid replicator" means a polynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permitting replication in E. coli, and pUB110, pE194, pTA1060, and ρΑΜβΙ permitting replication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the 2 micron origin of replication, ARS1 , ARS4, the combination of ARS1 and CEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cell are AMA1 and ANSI (Gems et al. , 1991 , Gene 98: 61-67; Cullen ef a/. , 1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of the AMA1 gene and construction of plasmids or vectors comprising the gene can be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may be inserted into a host cell to increase production of a polypeptide. An increase in the copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selectable marker gene with the polynucleotide where cells containing amplified copies of the selectable marker gene, and thereby additional copies of the polynucleotide, can be selected for by cultivating the cells in the presence of the appropriate selectable agent.

The procedures used to ligate the elements described above to construct the recombinant expression vectors of the present invention are well known to one skilled in the art (see, e.g., Sambrook et al. , 1989, supra). Host Cells

The present disclosure also relates to recombinant host cells, comprising a polynucleotide as described herein operably linked to one or more control sequences that direct the production of a polypeptide. A construct or vector comprising a polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extra-chromosomal vector as described earlier. The term "host cell" encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of a host cell will to a large extent depend upon the gene encoding the polypeptide and its source.

The host cell may be any cell useful in the recombinant production of a polypeptide of the present invention, e.g. , a prokaryote or a eukaryote.

The introduction of DNA into an E. coli cell may be effected by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166: 557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16: 6127-6145). The introduction of DNA into a Streptomyces cell may be effected by protoplast transformation, electroporation (see, e.g. , Gong et a/. , 2004, Folia Microbiol. (Praha) 49: 399-405), conjugation (see, e.g., Mazodier ei a/. , 1989, J. Bacterioi. 171 : 3583-3585), or transduction (see, e.g., Burke et al , 2001 , Proc. Natl. Acad. Sci. USA 98: 6289-6294). The introduction of DNA into a Pseudomonas cell may be effected by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64: 391-397) or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71 : 51-57).

The cleaning composition may be in any convenient form, e.g., a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid.

Pouches can be configured as single or multicompartments. It can be of any form, shape and material which is suitable for hold the composition, e.g. without allowing the release of the composition to release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected polyacrylates, and water soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin, poly methacrylates, most preferably polyvinyl alcohol copolymers and, hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymer in the film for example PVA is at least about 60%. Preferred average molecular weight will typically be about 20,000 to about 150,000. Films can also be of blended compositions comprising hydrolytically degradable and water soluble polymer blends such as polylactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by MonoSol LLC, Indiana, USA) plus plasticisers like glycerol, ethylene glycerol, propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water-soluble film. The compartment for liquid components can be different in composition than compartments containing solids: US2009/0011970 A1.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

A liquid or gel detergent, which is not unit dosed, may be aqueous, typically containing at least 20% by weight and up to 95% water, such as up to about 70% water, up to about 65% water, up to about 55% water, up to about 45% water, up to about 35% water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent may contain from 0-30% organic solvent.

A liquid or gel detergent may be non-aqueous. Laundry soap bars

The polypeptides disclosed herein may be added to laundry soap bars and used for hand washing laundry, fabrics and/or textiles. The term laundry soap bar includes laundry bars, soap bars, combo bars, syndet bars and detergent bars, with the term "cleaning composition" or "detergent composition", as used herein, also including such soap bars. The types of bar usually differ in the type of surfactant they contain, and the term laundry soap bar includes those containing soaps from fatty acids and/or synthetic soaps. The laundry soap bar has a physical form which is solid and not a liquid, gel or a powder at room temperature. The term solid is defined as a physical form which does not significantly change over time, i.e. if a solid object (e.g. laundry soap bar) is placed inside a container, the solid object does not change to fill the container it is placed in. The bar is a solid typically in bar form but can be in other solid shapes such as round or oval.

The laundry soap bar may contain one or more additional enzymes, protease inhibitors such as peptide aldehydes (or hydrosulfite adduct or hemiacetal adduct), boric acid, borate, borax and/or phenylboronic acid derivatives such as 4-formylphenylboronic acid, one or more soaps or synthetic surfactants, polyols such as glycerine, pH controlling compounds such as fatty acids, citric acid, acetic acid and/or formic acid, and/or a salt of a monovalent cation and an organic anion wherein the monovalent cation may be for example Na⁺, K⁺ or NH4⁺ and the organic anion may be for example formate, acetate, citrate or lactate such that the salt of a monovalent cation and an organic anion may be, for example, sodium formate.

The laundry soap bar may also contain complexing agents like EDTA and HEDP, perfumes and/or different type of fillers, surfactants e.g. anionic synthetic surfactants, builders, polymeric soil release agents, detergent chelators, stabilizing agents, fillers, dyes, colorants, dye transfer inhibitors, alkoxylated polycarbonates, suds suppressers, structurants, binders, leaching agents, bleaching activators, clay soil removal agents, anti-redeposition agents, polymeric dispersing agents, brighteners, fabric softeners, perfumes and/or other compounds known in the art.

The laundry soap bar may be processed in conventional laundry soap bar making equipment such as but not limited to: mixers, plodders, e.g a two stage vacuum plodder, extruders, cutters, logo- stampers, cooling tunnels and wrappers. The invention is not limited to preparing the laundry soap bars by any single method. The premix may be added to the soap at different stages of the process. For example, the premix containing a soap, hexosaminidase, optionally one or more additional enzymes, a protease inhibitor, and a salt of a monovalent cation and an organic anion may be prepared and the mixture is then plodded. The hexosaminidase and optional additional enzymes may be added at the same time as the protease inhibitor for example in liquid form. Besides the mixing step and the plodding step, the process may further comprise the steps of milling, extruding, cutting, stamping, cooling and/or wrapping.

Formulation of enzyme in co-granule

The polypeptides disclosed herein may be formulated as a granule for example as a co-granule that combines one or more enzymes. Each enzyme will then be present in more granules securing a more uniform distribution of enzymes in the detergent. This also reduces the physical segregation of different enzymes due to different particle sizes. Methods for producing multi-enzyme co-granulate for the detergent industry are disclosed in the IP.com disclosure IPCOM000200739D.

Another example of formulation of enzymes using co-granulates are disclosed in WO

Assays

Wash assays

Mini Launder-O-Meter (MiniLOM) Model Wash System

MiniLOM is a mini wash system in which washes are performed in 50 ml test tubes placed in a Stuart rotator. Each tube simulates one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved via rotation (typically 20rpm), and the temperature is controlled by placement of the rotator in a heating cabinet/room.

Terg-O-timeter (TOM) wash assay

The Tergo-To-Meter (TOM) is a medium scale model wash system that can be applied to test 12 different wash conditions simultaneously. A TOM is basically a large temperature controlled water bath with up to 12 open metal beakers submerged into it. Each beaker constitutes one small top loader style washing machine and during an experiment, each of them will contain a solution of a specific detergent/enzyme system and the soiled and unsoiled fabrics its performance is tested on. Mechanical stress is achieved by a rotating stirring arm, which stirs the liquid within each beaker. Because the TOM beakers have no lid, it is possible to withdraw samples during a TOM experiment and assay for information on-line during wash. The TOM model wash system is mainly used in medium scale testing of detergents and enzymes at US or LA AP wash conditions. In a TOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the TOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in top loader washing machines. Equipment: The water bath with 12 steel beakers and 1 rotating arm per beaker with capacity of 500 or 1200ml_ of detergent solution. Temperature ranges from 5 to 80°C. The water bath must be filled up with deionised water. Rotational speed can be set up to 70 to 120 rpm/min. Set temperature in the Terg-O-Tometer and start the rotation in the water bath. Wait for the temperature to adjust (tolerance is +/- 0,5°C). All beakers shall be clean and without traces of prior test material. The wash solution with desired amount of detergent, temperature and water hardness is prepared in a bucket. The detergent is allowed to dissolve during magnet stirring for 10 min. Wash solution shall be used within 30 to 60 min after preparation. 800 ml wash solution is added into a TOM beaker. The wash solution is agitated at 120 rpm and optionally one or more enzymes are added to the beaker. The swatches are sprinkled into the beaker and then the ballast load. Time measurement starts when the swatches and ballast are added to the beaker. The swatches are washed for 20 minutes after which agitation is terminated. The wash load is subsequently transferred from the TOM beaker to a sieve and rinse with cold tap water. The soiled swatches are separated from the ballast load. The soil swatches are transferred to a 5L beaker with cold tap water under running water for 5 minutes. The ballast load is kept separately for the coming inactivation. The water is gently pressed out of the swatches by hand and placed on a tray covered with a paper. Another paper is placed on top of the swatches. The swatches are allowed to dry overnight before subjecting the swatches to analysis, such as measuring the color intensity using a Color Eye.

The present invention is further described by the following examples that should not be construed as limiting the scope of the invention. Assay I: testing of hexosaminidase activity

The hexosaminidase activity of the polypeptides listed in the table below was determined using 4-nitrophenyl N-acetyl-p-D-glucosaminide (Sigma-Aldrich) as substrate. The enzymatic reaction was performed in triplicates in a 96 well flat bottom polystyrene microtiter plate (Thermo Scientific) with the following conditions: 50 m 2-(N-morpholino) ethanesulfonic acid pH 6 buffer, 1.5 mg/ml 4-nitrophenyl N-acetyl- -D-glucosaminide and 20 μg/ml purified enzyme sample in a total reaction volume of 100 μΙ. Blank samples without polypeptide were run in parallel. The reactions were carried out at 37°C in a Thermomixer comfort (Eppendorf). After 10 minutes of incubation, 5 μΙ 1 M NaOH was added to each reaction mixture to stop the enzymatic reaction. The absorbance was read at 405 nm using a POLARstar Omega plate reader (BMG LABTECH) to estimate the formation of 4-nitrophenolate ion released because of enzymatic hydrolysis of the 4-nitrophenyl N-acetyl- -D-glucosaminide substrate.

The results are summarized in table 2 below. The table shows the average absorbance measured at 405 nm for each reaction performed in triplicates. It is seen that the absorbance is higher for the reaction carried out with all the polypeptides listed in the table below compared to blank without polypeptide which demonstrates that all the tested polypeptides exhibit hexosaminidase activity.

Examples

Example 1 :

The DNA encoding the polypeptides having hexosaminidase activity comprising the polypeptide having SEQ ID NO 24 from Actinobacillus pleuropneumoniae, the polypeptide having SEQ ID NO 17 from Aggregatibacter actinomycetemcomitans, the polypeptide having SEQ ID NO 18 from Haemophilus sputorum, the polypeptide having SEQ ID NO 19 from Actinobacillus suis, the polypeptide having SEQ ID NO 21 from Actinobacillus equuli subsp. Equuli, the polypeptide having SEQ ID NO 22 from Aggregatibacter actinomycetemcomitans, the polypeptide having SEQ ID NO 23 Aggregatibacter actinomycetemcomitans respectively, were obtained from public databases (see public database entry in Table 3 below) or from the genome of Actinobacillus capsulatus DSM 19761 corresponding to NCBI taxonomy ID 1 120931 for the polypeptide having SEQ ID NO 20.

The codon optimized synthetic DNA encoding the mature peptide sequences of the polypeptides having hexosaminidase activity were ordered from the company Geneart.

Table 3:

Example 2: Cloning and expression of polypeptides having hexosaminidase activity

The codon optimized synthetic genes encoding the polypeptides with SEQ ID NOS 17, 18, 19, 20, 21 , 22, 23 and 24 having hexosaminidase activity were inserted into a Bacillus expression vector as described in WO 12/025577. Briefly, the DNA encoding the polypeptides with SEQ ID NOS 17, 18, 19, 20, 21 , 22, 23 and 24 genes were cloned in frame to a Bacillus clausii secretion signal (BcSP; with the following amino acid sequence: MKKPLGKIVASTALLISVAFSSSIASA (SEQ ID NO:25)). BcSP replaced the native secretion signal in the gene. Downstream of the BcSP sequence, an affinity tag sequence was introduced to ease the purification process (His-tag; with the following amino acid sequence: HHHHHHPR (SEQ ID NO: 26). The gene that was expressed therefore comprised the BcSP sequence followed by the His-tag sequence followed by the polypeptide sequence (as shown in the polypeptide with SEQ ID NOS 17, 18, 19, 20, 21 , 22, 23 and 24, abbreviated GH20 in the following. The final expression plasmid (BcSP-His-tag-GH20) was transformed into a Bacillus subtilis expression host. The GH20 BcSP-fusion gene was integrated by homologous recombination into the Bacillus subtilis host cell genome upon transformation. The gene construct was expressed under the control of a triple promoter system (as described in WO 99/43835). The gene coding for chloramphenicol acetyltransferase was used as maker (as described in (Diderichsen et a\., 1993, Plasmid 30: 312-315)). Transformants were selected on LB media agar supplemented with 6 micrograms of chloramphenicol per ml. One recombinant Bacillus subtilis clone containing the GH20 expression construct was selected and was cultivated on a rotary shaking table in 500 ml baffled Erlenmeyer flasks each containing 100 ml yeast extract-based media. After 3-5 days' cultivation time at 30 °C to 37°C, enzyme containing supernatants were harvested by centrifugation and the polypeptides of the invention were purified by His-tag purification.

Example 3: His tag purification method

The His-tagged polypeptides were purified by immobilized metal chromatography (IMAC) using Ni²⁺ as the metal ion on 5 ml. HisTrap Excel columns (GE Healthcare Life Sciences). The purification took place at pH 7 and the bound proteins were eluted with imidazole. The purity of the purified enzymes was checked by SDS-PAGE and the concentration of each enzyme determined by Absorbance 280 nm after a buffer exchange in 50mM HEPES, 100mM NaCI pH7.0 Example 4: Biofilm assay

Staphylococcus aureus was kindly provided by Inigo Lasa (Valle et al., Mol Microbiol.2003 May; 48 (4):1075-87). The strain was grown on trypticase soy agar (TSA) at 37°C overnight. Next day, a single colony was transferred to 15 ml tripticase soy broth (TSB) and incubated 5 hours at 37°C under shaking. The culture was diluted 1 : 100 in TSB+1% glucose and 100 μί of the bacterial suspension was transferred to each well of a 96-well microtiter plates (Thermo Scientific, Nunclon Delta Surface, cat # 167008) and incubated 24 hours at 37°C without shaking. Supernatant was aspirated and wells were washed with 100 μί of 0.9% sodium chloride and filled with 100 μί of either hard water or 3.3 gr/L Model detergent A containing 0 (control) or 20, 10, 5, 2.5, 1.25, 0.62, 0.31 , 0.16, 0.08, 0.04, 0.02 and 0.01 g/mL of enzyme (the polypeptides with SEQ ID NO 24 SEQ ID NO 18, SEQ ID NO 19, SEQ ID NO 20 and SEQ ID NO 21 ). After incubation at 37°C for 1 hour, wells were washed with water and stained for 15 min with 100 μΙ. of 0.095% crystal violet solution (SIGMA V5265). Wells were then rinsed twice with 100 μL water, dried and the plates were scanned. The lowest concentration of each enzyme that could reduce the visible formation of biofilm of the S. aureus organism after 1 hour incubation, in the presence and absence of detergent was determined (see Table 4). All enzymes were assayed per duplicate with similar results.

Example 5 Deep-cleaning of hexosaminidases in liquid model detergent

Staphylococcus aureus (kind gift from Inigo Lasa (Valle et al., Mol Microbiol .2003 May; 48 (4):1075-87) was used as model microorganism in the present example. S.aureus was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131 ; Oxoid Ltd, Basingstoke, UK) and incubated for 1 day at 37°C. A single colony was inoculated into 10 mL of TSB and the culture was incubated for 16 hours at 37°C with shaking (200 rpm). After propagation, the S.aureus culture was diluted (1 :100) in fresh TSB + 1 % glucose (24563; Roquette Freres) and 2 mL aliquots were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, NY, USA), in which round swatches (diameter 2 cm) of sterile polyester (WFK30A) had been placed. Sterile TSB + 1 % glucose was added to control wells. After 48 h at 37°C (static incubation), the swatches were rinsed twice with 15°dH water. Five rinsed swatches (sterile or with S.aureus) were placed in 50 mL test tubes and 10 mL of wash liquor (15°dH water with 0.2 g/L iron(lll) oxide nanopowder (544884; Sigma-Aldrich) with 3.33g/L liquid model A detergent) and 2ppm enzyme (mature polypeptide of SEQ ID NO 2, 4, 6, 8, 10, 12, 14 or 16) were added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37°C at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15°dH water and dried on filter paper over night.

The color difference (L) values were measured using a Handheld Minolta CR-300, and are displayed in table 5.

Delta values (L (swatch washed with enzyme)^— L (swatch washed without enzyme)) are also indicated.

The results show that the hexosaminidases display deep-cleaning properties in model detergent A.

Table 5. Deep-cleaning effects of dispersins in model detergent A

The results show that all the polypeptides of the invention have deep cleaning properties, when compared to samples comprising no enzyme. Example 6 Deep-cleaning of hexosaminidases in nonionic liquid model detergent

Staphylococcus aureus biofilms were grown on textile swatches (wfk30A) as described in example 5.

Five rinsed swatches (sterile or with S.aureus) were placed in 50 mL conical centrifuge tubes (339652;

Thermo Scientific) and 10 mL of wash liquor (15°dH water with 0.2 g/L iron(lll) oxide nanopowder

(544884; Sigma-Aldrich) with 3.33g/L liquid nonionic model detergent) and 2ppm enzyme was added to each tube. Washes without enzyme were included as controls. The tubes were placed on a Stuart rotator and incubated for 1 hour at 37°C at 20rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15°dH water and dried on filter paper over night.

The color difference (L) values were measured using a Handheld Minolta CR-300, and are displayed in table 5. Delta values (L (swatch as ed wit enzyme) - L (swatch washed without enzyme)) are also indicated. The results show that the dispersins also show deep-cleaning properties in nonionic liquid model detergent.

Example 7: Construction of clades and phylogenetic trees

The Glyco_hydro_20 domain includes the polypeptides of the invention having hexosaminidase e.g. PNAG activity and comprises clusters such as the clades. A phylogenetic tree was constructed, of polypeptide sequences containing a Glyco_hydro_20 domain, as defined in PFAM (PF00728, Pfam version 31.0 Finn (2016). Nucleic Acids Research, Database Issue 44:D279-D285). The phylogenetic tree was constructed from a multiple alignment of mature polypeptide sequences containing at least one Glyco_hydro_20 domain. The sequences were aligned using the MUSCLE algorithm version 3.8.31 (Edgar, 2004. Nucleic Acids Research 32(5): 1792-1797), and the trees were constructed using FastTree version 2.1.8 (Price et al., 2010, PloS one 5(3)) and visualized using iTOL (Letunic & Bork, 2007. Bioinformatics 23(1 ): 127-128). The polypeptide comprises of the Glyco_hydro_20 domain comprises several motifs one example is GXDE (SEQ ID NO 27) situated in positions corresponding to positions 166 to 169 in Haemophilus sputorum HK 2154 (SEQ ID NO 18). Residues D and E are the key catalytic residues of Glyco_hydro_20 enzymes (position 168 to 169 in SEQ ID NO 18). As already described the polypeptides of the invention having hexosaminidase e.g. PNAG activity may comprise the structural domains of Glyco_hydro_20. The polypeptides in Glyco_hydro_20 can be separated into multiple distinct sub-clusters, or clades, where we denoted the clades listed below. The distinct motifs for each clade are described in details below.

Generation of LES domain

A domain, preferably shared by the polypeptides of the invention, was identified. This domain has not been described previously. The domain is termed LES and polypeptides of this domain comprises Glyco_hydro_20 domain polypeptides of bacterial origin and are in addition to having PNAG activity, characterized by comprising certain motifs. The polypeptides of the domain comprise the motif example [EQ][NRSHA][YVFL][AGSTC][IVLF][EAQYN][SN] (SEQ ID NO: 28), corresponding to pos 46 to 52 of SEQ ID NO 18.

Generation of HFH clade

The HFH clade comprises LES domain polypeptides of bacterial origin, having hexosaminidase e.g. PNAG activity. The polypeptides of the clade comprise the motif example HFHIGG (SEQ ID NO: 29), corresponding to pos 162 to 167 of SEQ ID NO 18, where H (corresponding to position 162 of SEQ ID NO 18) is fully conserved in HFH clade. Another motif which may be comprised by the polypeptides of the HFH clade is FLHLHF (SEQ ID NO: 30), corresponding to amino acids 37 to 42 in SEQ ID NO 18, where H at position 41 is part of the active site. A further motif which may be comprised by the polypeptides of the HFH clade is DHENYA (SEQ ID NO: 31 ), 44 to 49 in SEQ ID NO 18, where E at position 46 is part of the active site.

An alignment of the polypeptides of the invention comprised in the clade is shown in Figure 2.

A phylogenetic tree of the HFH clade is shown in Figure 3.
