[0001]
  • FIELD OF THE INVENTION
  • The present invention relates to variants (mutants) of parent Termamyl-like alpha-amylases, which variant has alpha-amylase activity and exhibits an alteration in at least one of the following properties relative to said parent alpha-amylase: stability under, e.g., high temperature and/or low pH conditions, in particular at low calcium concentrations. The variant of the invention are suitable for starch conversion, ethanol production, laundry wash, dish wash, hard surface cleaning, textile desizing, and/or sweetner production. [0002]
  • BACKGROUND OF THE INVENTION
  • Alpha-Amylases (alpha-1,4-glucan-4-glucanohydrolases, E.C. 3.2.1.1) constitute a group of enzymes, which catalyze hydrolysis of starch and other linear and branched 1,4-glucosidic oligo- and polysaccharides. [0003]
  • BRIEF DISCLOSURE OF THE INVENTION
  • The object of the present invention is to provide Termamyl-like amylases which variants in comparison to the corresponding parent alpha-amylase, i.e., un-mutated alpha-amylase, has alpha-amylase activity and exhibits an alteration in at least one of the following properties relative to said parent alpha-amylase: stability under, e.g., high temperature and/or low pH conditions, in particular at low calcium concentrations. [0004]
  • Nomenclature [0005]
  • In the present description and claims, the conventional one-letter and three-letter codes for amino acid residues are used. For ease of reference, alpha-amylase variants of the invention are described by use of the following nomenclature: [0006]
  • Original amino acid(s): position(s): substituted amino acid(s) [0007]
  • According to this nomenclature, for instance the substitution of alanine for asparagine in position 30 is shown as: [0008]
  • Ala30Asn or A30N [0009]
  • a deletion of alanine in the same position is shown as: [0010]
  • Ala30* or A30* [0011]
  • and insertion of an additional amino acid residue, such as lysine, is shown as: [0012]
  • Ala30AlaLys or A30AK [0013]
  • A deletion of a consecutive stretch of amino acid residues, such as amino acid residues 30-33, is indicated as (30-33)* or Δ(A30-N33). [0014]
  • Where a specific alpha-amylase contains a “deletion” in comparison with other alpha-amylases and an insertion is made in such a position this is indicated as: [0015]
  • *36Asp or *36D [0016]
  • for insertion of an aspartic acid in position 36. Multiple mutations are separated by plus signs, i.e.: [0017]
  • Ala30Asp+Glu34Ser or A30N+E34S representing mutations in positions 30 and 34 substituting alanine and glutamic acid for asparagine and serine, respectively. [0018]
  • When one or more alternative amino acid residues may be inserted in a given position it is indicated as A30N,E or [0019]
  • A30N or A30E [0020]
  • Furthermore, when a position suitable for modification is identified herein without any specific modification being suggested, it is to be understood that any amino acid residue may be substituted for the amino acid residue present in the position. Thus, for instance, when a modification of an alanine in position 30 is mentioned, but not specified, it is to be understood that the alanine may be deleted or substituted for any other amino acid, i.e., any one of: [0021]
  • R,N,D,A,C,Q,E,G,H,I,L,K,M,F,P,S,T,W,Y,V. [0022]
  • Further, “A30X” means any one of the following substitutions: [0023]
  • A30R, A30N, A30D, A30C, A30Q, A30E, A30G, A30H, A30I, A30L, A30K, A30M, A30F, A30P, A30S, A30T, A30W, A30Y, or A30V; or in short: A30R,N,D,C,Q,E,G,H,I,L,K,M,F,P,S,T,W,Y,V. [0024]
  • If the parent enzyme—used for the numbering—already has the amino acid residue in question suggested for substitution in that position the following nomenclature is used: [0025]
  • “X30N” or “X30N,V” in the case where for instance one or N or V is present in the wildtype. Thus, it means that other corresponding parent enzymes are substituted to an “Asn” or “Val” in position 30.[0026]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is an alignment of the amino acid sequences of five parent Termamyl-like alpha-amylases. The numbers on the extreme left designate the respective amino acid sequences as follows: [0027]

  • For instance, the [0036] B. licheniformis alpha-amylase comprising the amino acid sequence shown in SEQ ID NO: 8 (commercially available as Termamyl™) has been found to be about 81% homologous with the B. amyloliquefaciens alpha-amylase comprising the amino acid sequence shown in SEQ ID NO: 10 and about 65% homologous with the B. stearothermophilus alpha-amylase (BSG) comprising the amino acid sequence shown in SEQ ID NO: 6. Further homologous alpha-amylases include SP690 and SP722 disclosed in WO 95/26397 and further depicted in SEQ ID NO: 2 and SEQ ID NO: 4, respectively, herein. Other amylases are the AA560 alpha-amylase derived from Bacillus sp. and shown in SEQ ID NO: 12, and the #707 alpha-amylase derived from Bacillus sp., shown in SEQ ID NO: 13 and described by Tsukamoto et al., Biochemical and Biophysical Research Communications, 151 (1988), pp. 25-31.
  • The KSM AP1378 alpha-amylase is disclosed in WO 97/00324 (from KAO Corporation). [0037]
  • Still further homologous alpha-amylases include the alpha-amylase produced by the [0038] B. licheniformis strain described in EP 0252666 (ATCC 27811), and the alpha-amylases identified in WO 91/00353 and WO 94/18314. Other commercial Termamyl-like alpha-amylases are comprised in the products sold under the following tradenames: Optitherm™ and Takatherm™ (Solvay); Maxamyl™ (available from Gist-brocades/Genencor), Spezym AA™ and Spezyme Delta AA™ (available from Genencor), and Keistase™ (available from Daiwa), Dex lo, GC 521 (available from Genencor) and Ultraphlow (from Enzyme Biosystems).
  • Because of the substantial homology found between these alpha-amylases, they are considered to belong to the same class of alpha-amylases, namely the class of “Termamyl-like alpha-amylases”. [0039]
  • Accordingly, in the present context, the term “Termamyl-like” alpha-amylase” is intended to indicate an alpha-amylase, in particular Bacillus alpha-amylase, which, at the amino acid level, exhibits a substantial identity to Termamyl, i.e., the [0040] B. licheniformis alpha-amylase having the amino acid sequence shown in SEQ ID NO: 8, herein.
  • In other words, all the following alpha-amylases, which has the amino acid sequences shown in SEQ ID NOS: 2, 4, 6, 8, 10, 12 and 13 herein are considered to be “Termamyl-like alpha-amylase”. Other Termamyl-like alpha-amylases are alpha-amylases i) which displays at least 60%, such as at least 70%, e.g., at least 75%, or at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 99% homology (identity) with at least one of said amino acid sequences shown in SEQ ID NOS: 2, 4, 6, 8, 10, 12, and 13, and/or is encoded by a DNA sequence which hybridizes to the DNA sequences encoding the above-specified alpha-amylases which are apparent from SEQ ID NOS: 1, 3, 5, 7, 9, and of the present specification (which encoding sequences encode the amino acid sequences shown in SEQ ID NOS: 2, 4, 6, 8, 10 and 12 herein, respectively). [0041]
  • Homology [0042]
  • The homology may be determined as the degree of identity between the two sequences indicating a derivation of the first sequence from the second. The homology may suitably be determined by means of computer programs known in the art such as GAP provided in the GCG program package (described above). Thus, Gap GCGv8 may be used with the default scoring matrix for identity and the following default parameters: GAP creation penalty of 5.0 and GAP extension penalty of 0.3, respectively for nucleic acidic sequence comparison, and GAP creation penalty of 3.0 and GAP extension penalty of 0.1, respectively, for protein sequence comparison. GAP uses the method of Needleman and Wunsch, (1970), J.Mol. Biol. 48, p.443-453, to make alignments and to calculate the identity. [0043]
  • A structural alignment between Termamyl (SEQ ID NO: 8) and, e.g., another alpha-amylase may be used to identify equivalent/corresponding positions in other Termamyl-like alpha-amylases. One method of obtaining said structural alignment is to use the Pile Up programme from the GCG package using default values of gap penalties, i.e., a gap creation penalty of 3.0 and gap extension penalty of 0.1. Other structural alignment methods include the hydrophobic cluster analysis (Gaboriaud et al., (1987), FEBS LETTERS 224, pp. 149-155) and reverse threading (Huber, T; Torda, AE, PROTEIN SCIENCE Vol. 7, No. 1 pp. 142-149 (1998). [0044]
  • Hybridisation [0045]
  • The oligonucleotide probe used in the characterisation of the Termamyl-like alpha-amylase above may suitably be prepared on the basis of the full or partial nucleotide or amino acid sequence of the alpha-amylase in question. [0046]
  • Suitable conditions for testing hybridisation involve pre-soaking in 5×SSC and prehybridizing for 1 hour at 40° C. in a solution of 20% formamide, 5×Denhardt's solution, 50 mM sodium phosphate, pH 6.8, and 50 mg of denatured sonicated calf thymus DNA, followed by hybridisation in the same solution supplemented with 100 mM ATP for 18 hours at 40° C., followed by three times washing of the filter in 2×SSC, 0.2% SDS at 40° C. for 30 minutes (low stringency), preferred at 50° C. (medium stringency), more preferably at 65° C. (high stringency), even more preferably at 75° C. (very high stringency). More details about the hybridisation method can be found in Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989. [0047]
  • In the present context, “derived from” is intended not only to indicate an alpha-amylase produced or producible by a strain of the organism in question, but also an alpha-amylase encoded by a DNA sequence isolated from such strain and produced in a host organism transformed with said DNA sequence. Finally, the term is intended to indicate an alpha-amylase, which is encoded by a DNA sequence of synthetic and/or cDNA origin and which has the identifying characteristics of the alpha-amylase in question. The term is also intended to indicate that the parent alpha-amylase may be a variant of a naturally occurring alpha-amylase, i.e., a variant, which is the result of a modification (insertion, substitution, deletion) of one or more amino acid residues of the naturally occurring alpha-amylase. [0048]
  • Parent Termamyl-like Alpha-amylases [0049]
  • According to the invention all Termamy-like alpha-amylases, as defined above, may be used as the parent (i.e., backbone) alpha-amylase. In a preferred embodiment of the invention the parent alpha-amylase is derived from [0050] B. licheniformis, e.g., one of those referred to above, such as the B. licheniformis alpha-amylase having the amino acid sequence shown in SEQ ID NO: 8.
  • Parent Hybrid Termamyl-like Alpha-amylases [0051]
  • The parent alpha-amylase (i.e., backbone alpha-amylase) may also be a hybrid alpha-amylase, i.e., an alpha-amylase, which comprises a combination of partial amino acid sequences derived from at least two alpha-amylases. [0052]
  • The parent hybrid alpha-amylase may be one, which on the basis of amino acid homology (identity) and/or DNA hybridization (as defined above) can be determined to belong to the Termamyl-like alpha-amylase family. In this case, the hybrid alpha-amylase is typically composed of at least one part of a Termamyl-like alpha-amylase and part(s) of one or more other alpha-amylases selected from Termamyl-like alpha-amylases or non-Termamyl-like alpha-amylases of microbial (bacterial or fungal) and/or mammalian origin. [0053]
  • Thus, the parent hybrid alpha-amylase may comprise a combination of partial amino acid sequences deriving from at least two Termamyl-like alpha-amylases, or from at least one Termamyl-like and at least one non-Termamyl-like bacterial alpha-amylase, or from at least one Termamyl-like and at least one fungal alpha-amylase. The Termamyl-like alpha-amylase from which a partial amino acid sequence derives, may be any of the specific Termamyl-like alpha-amylase referred to herein. [0054]
  • For instance, the parent alpha-amylase may comprise a C-terminal part of an alpha-amylase derived from a strain of [0055] B. licheniformis, and a N-terminal part of an alpha-amylase derived from a strain of B. amyloliquefaciens or from a strain of B. stearothermophilus. For instance, the parent alpha-amylase may comprise at least 430 amino acid residues of the C-terminal part of the B. licheniformis alpha-amylase, and may, e.g., comprise a) an amino acid segment corresponding to the 37 N-terminal amino acid residues of the B. amyloliquefaciens alpha-amylase having the amino acid sequence shown in SEQ ID NO: 10 and an amino acid segment corresponding to the 445 C-terminal amino acid residues of the B. licheniformis alpha-amylase having the amino acid sequence shown in SEQ ID NO: 8, or a hybrid Termamyl-like alpha-amylase being identical to the Termamyl sequence, i.e., the Bacillus licheniformis alpha-amylase shown in SEQ ID NO: 8, except that the N-terminal 35 amino acid residues (of the mature protein) has been replaced by the N-terminal 33 residues of BAN (mature protein), i.e., the Bacillus amyloliquefaciens alpha-amylase shown in SEQ ID NO: 10; or b) an amino acid segment corresponding to the 68 N-terminal amino acid residues of the B. stearothermophilus alpha-amylase having the amino acid sequence shown in SEQ ID NO: 6 and an amino acid segment corresponding to the 415 C-terminal amino acid residues of the B. licheniformis alpha-amylase having the amino acid sequence shown in SEQ ID NO: 8.

[0092]
  • Stability [0093]
  • In the context of the present invention, mutations (including amino acid substitutionsa and deletion) of importance with respect to achieving altered stability, in particular improved stability (i.e., higher or lower), at especially high temperatures (i.e., 70-120° C.) and/or extreme pH (i.e. low or high pH, i.e, pH 4-6 or pH 8-11, respectively), in particular at free (i.e., unbound, therefore in solution) calcium concentrations below 60 ppm, include any of the mutations listed in the “Altered properties” section. The stability may be determined as described in the “Materials & Methods” section below. [0094]
  • General Mutations in Variants of the Invention [0095]
  • A variant of the invention may in one embodiment comprise one or more modifications in addition to those outlined above. Thus, it may be advantageous that one or more Proline (Pro) residues present in the part of the alpha-amylase variant which is modified is/are replaced with a non-Proline residue which may be any of the possible, naturally occurring non-Proline residues, and which preferably is an Alanine, Glycine, Serine, Threonine, Valine or Leucine. [0096]
  • Analogously, in one embodiment one or more Cysteine residues present in the parent alpha-amylase may be replaced with a non-Cysteine residue such as Serine, Alanine, Threonine, Glycine, Valine or Leucine. [0097]
  • Furthermore, a variant of the invention may—either as the only modification or in combination with any of the above outlined modifications—be modified so that one or more Asp and/or Glu present in an amino acid fragment corresponding to the amino acid fragment 185-209 of SEQ ID NO: 10 is replaced by an Asn and/or Gln, respectively. Also of interest is the replacement, in the Termamyl-like alpha-amylase, of one or more of the Lys residues present in an amino acid fragment corresponding to the amino acid fragment 185-209 of SEQ ID NO: 10 by an Arg. [0098]
  • It is to be understood that the present invention encompasses variants incorporating two or more of the above outlined modifications. [0099]
  • Furthermore, it may be advantageous to introduce mutations in one or more of the following positions (using SEQ ID NO: 8 (Termamyl) for the numbering): [0100]
  • M15, V128, A111, H133, W138, T149, M197, N188, A209, A210, H405, T412, in particular the following single, double or triple or multi mutations: [0101]

  • G475R, H133Y/S187D; H133Y/A209V. [0110]
  • Methods for Preparing Alpha-amylase Variants of the Invention [0111]
  • Several methods for introducing mutations into genes are known in the art. After a brief description of cloning of alpha-amylase-encoding DNA sequences, methods for generating mutations at specific sites within the alpha-amylase-encoding sequence will be discribed. [0112]
  • Cloning a DNA Sequence Encoding an Alpha-amylase [0113]
  • The DNA sequence encoding a parent alpha-amylase may be isolated from any cell or microorganism producing the alpha-amylase in question, using various methods well known in the art. First, a genomic DNA and/or cDNA library should be constructed using chromosomal DNA or messenger RNA from the organism that produces the alpha-amylase to be studied. Then, if the amino acid sequence of the alpha-amylase is known, homologous, labeled oligonucleotide probes may be synthesized and used to identify alpha-amylase-encoding clones from a genomic library prepared from the organism in question. Alternatively, a labeled oligonucleotide probe containing sequences homologous to a known alpha-amylase gene could be used as a probe to identify alpha-amylase-encoding clones, using hybridization and washing conditions of lower stringency. [0114]
  • Yet another method for identifying alpha-amylase-encoding clones would involve inserting fragments of genomic DNA into an expression vector, such as a plasmid, transforming alpha-amylase-negative bacteria with the resulting genomic DNA library, and then plating the transformed bacteria onto agar containing a substrate for alpha-amylase, thereby allowing clones expressing the alpha-amylase to be identified. [0115]
  • Alternatively, the DNA sequence encoding the enzyme may be prepared synthetically by established standard methods, e.g., the phosphoroamidite method described by S. L. Beaucage and M. H. Caruthers, Tetrahedron Letters 22, 1981, pp. 1859-1869, or the method described by Matthes et al., The EMBO J. 3, 1984, pp. 801-805. In the phosphoroamidite method, oligonucleotides are synthesized, e.g., in an automatic DNA synthesizer, purified, annealed, ligated and cloned in appropriate vectors. [0116]
  • Finally, the DNA sequence may be of mixed genomic and synthetic origin, mixed synthetic and cDNA origin or mixed genomic and cDNA origin, prepared by ligating fragments of synthetic, genomic or cDNA origin (as appropriate, the fragments corresponding to various parts of the entire DNA sequence), in accordance with standard techniques. The DNA sequence may also be prepared by polymerase chain reaction (PCR) using specific primers, for instance as described in U.S. Pat. No. 4,683,202 or R. K. Saiki et al., Science 239, 1988, pp. 487-491. [0117]
  • Site-directed Mutagenesis [0118]
  • Once an alpha-amylase-encoding DNA sequence has been isolated, and desirable sites for mutation identified, mutations may be introduced using synthetic oligonucleotides. These oligonucleotides contain nucleotide sequences flanking the desired mutation sites; mutant nucleotides are inserted during oligonucleotide synthesis. In a specific method, a single-stranded gap of DNA, bridging the alpha-amylase-encoding sequence, is created in a vector carrying the alpha-amylase gene. Then the synthetic nucleotide, bearing the desired mutation, is annealed to a homologous portion of the single-stranded DNA. The remaining gap is then filled in with DNA polymerase I (Klenow fragment) and the construct is ligated using T4 ligase. A specific example of this method is described in Morinaga et al. (1984). U.S. Pat. No. 4,760,025 disclose the introduction of oligonucleotides encoding multiple mutations by performing minor alterations of the cassette. However, an even greater variety of mutations can be introduced at any one time by the Morinaga method, because a multitude of oligonucleotides, of various lengths, can be introduced. [0119]
  • Another method for introducing mutations into alpha-amylase-encoding DNA sequences is described in Nelson and Long (1989). It involves the 3-step generation of a PCR fragment containing the desired mutation introduced by using a chemically synthesized DNA strand as one of the primers in the PCR reactions. From the PCR-generated fragment, a DNA fragment carrying the mutation may be isolated by cleavage with restriction endonucleases and reinserted into an expression plasmid. [0120]
  • Alternative methods for providing variants of the invention include gene shuffling, e.g., as described in WO 95/22625 (from Affymax Technologies N.V.) or in WO 96/00343 (from Novo Nordisk A/S), or other corresponding techniques resulting in a hybrid enzyme comprising the mutation(s), e.g., substitution(s) and/or deletion(s), in question. Examples of parent alpha-amylases, which suitably may be used for providing a hybrid with the desired mutations(s) according to the invention include the KSM-K36 and KSM-K38 alpha-amylases disclosed in EP 1,022,334 (hereby incorporated by reference). [0121]
  • Expression of Alpha-amylase Variants [0122]
  • According to the invention, a DNA sequence encoding the variant produced by methods described above, or by any alternative methods known in the art, can be expressed, in enzyme form, using an expression vector which typically includes control sequences encoding a promoter, operator, ribosome binding site, translation initiation signal, and, optionally, a repressor gene or various activator genes. [0123]
  • The recombinant expression vector carrying the DNA sequence encoding an alpha-amylase variant of the invention may be any vector, which may conveniently be subjected to recombinant DNA procedures, and the choice of vector will often depend on the host cell into which it is to be introduced. Thus, the vector may be an autonomously replicating vector, i.e., a vector which exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g., a plasmid, a bacteriophage or an extrachromosomal element, minichromosome or an artificial chromosome. Alternatively, the vector may be one which, when introduced into a host cell, is integrated into the host cell genome and replicated together with the chromosome(s) into which it has been integrated. [0124]
  • In the vector, the DNA sequence should be operably connected to a suitable promoter sequence. The promoter may be any DNA sequence, which shows transcriptional activity in the host cell of choice and may be derived from genes encoding proteins either homologous or heterologous to the host cell. Examples of suitable promoters for directing the transcription of the DNA sequence encoding an alpha-amylase variant of the invention, especially in a bacterial host, are the promoter of the lac operon of [0125] E.coli, the Streptomyces coelicolor agarase gene dagA promoters, the promoters of the Bacillus licheniformis alpha-amylase gene (amyL), the promoters of the Bacillus stearothermophilus maltogenic amylase gene (amyM), the promoters of the Bacillus amyloliquefaciens alpha-amylase (amyQ), the promoters of the Bacillus subtilis xylA and xylB genes etc. For transcription in a fungal host, examples of useful promoters are those derived from the gene encoding A. oryzae TAKA amylase, Rhizomucor miehei aspartic proteinase, A. niger neutral alpha-amylase, A. niger acid stable alpha-amylase, A. niger glucoamylase, Rhizomucor miehei lipase, A. oryzae alkaline protease, A. oryzae triose phosphate isomerase or A. nidulans acetamidase.
  • The expression vector of the invention may also comprise a suitable transcription terminator and, in eukaryotes, polyadenylation sequences operably connected to the DNA sequence encoding the alpha-amylase variant of the invention. Termination and polyadenylation sequences may suitably be derived from the same sources as the promoter. [0126]
  • The vector may further comprise a DNA sequence enabling the vector to replicate in the host cell in question. Examples of such sequences are the origins of replication of plasmids pUC19, pACYC177, pUB110, pE194, pAMB1 and pIJ702. [0127]
  • The vector may also comprise a selectable marker, e.g. a gene the product of which complements a defect in the host cell, such as the dal genes from [0128] B. subtilis or B. licheniformis, or one which confers antibiotic resistance such as ampicillin, kanamycin, chloramphenicol or tetracyclin resistance. Furthermore, the vector may comprise Aspergillus selection markers such as amdS, argB, niaD and sC, a marker giving rise to hygromycin resistance, or the selection may be accomplished by co-transformation, e.g., as described in WO 91/17243.
  • While intracellular expression may be advantageous in some respects, e.g., when using certain bacteria as host cells, it is generally preferred that the expression is extracellular. In general, the Bacillus alpha-amylases mentioned herein comprise a preregion permitting secretion of the expressed protease into the culture medium. If desirable, this preregion may be replaced by a different preregion or signal sequence, conveniently accomplished by substitution of the DNA sequences encoding the respective preregions. [0129]
  • The procedures used to ligate the DNA construct of the invention encoding an alpha-amylase variant, the promoter, terminator and other elements, respectively, and to insert them into suitable vectors containing the information necessary for replication, are well known to persons skilled in the art (cf., for instance, Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989). [0130]
  • The cell of the invention, either comprising a DNA construct or an expression vector of the invention as defined above, is advantageously used as a host cell in the recombinant production of an alpha-amylase variant of the invention. The cell may be transformed with the DNA construct of the invention encoding the variant, conveniently by integrating the DNA construct (in one or more copies) in the host chromosome. This integration is generally considered to be an advantage as the DNA sequence is more likely to be stably maintained in the cell. Integration of the DNA constructs into the host chromosome may be performed according to conventional methods, e.g., by homologous or heterologous recombination. Alternatively, the cell may be transformed with an expression vector as described above in connection with the different types of host cells. [0131]
  • The cell of the invention may be a cell of a higher organism such as a mammal or an insect, but is preferably a microbial cell, e.g., a bacterial or a fungal (including yeast) cell. [0132]
  • Examples of suitable bacteria are Gram-positive bacteria such as [0133] Bacillus subtilis, Bacillus licheniformis, Bacillus lentus, Bacillus brevis, Bacillus stearothermophilus, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus coagulans, Bacillus circulans, Bacillus lautus, Bacillus megaterium, Bacillus thuringiensis, or Streptomyces lividans or Streptomyces murinus, or gramnegative bacteria such as E.coli. The transformation of the bacteria may, for instance, be effected by protoplast transformation or by using competent cells in a manner known per se.
  • The yeast organism may favorably be selected from a species of Saccharomyces or Schizosaccharomyces, e.g. [0134] Saccharomyces cerevisiae. The filamentous fungus may advantageously belong to a species of Aspergillus, e.g., Aspergillus oryzae or Aspergillus niger. Fungal cells may be transformed by a process involving protoplast formation and transformation of the protoplasts followed by regeneration of the cell wall in a manner known per se. A suitable procedure for transformation of Aspergillus host cells is described in EP 238 023.
  • In a yet further aspect, the present invention relates to a method of producing an alpha-amylase variant of the invention, which method comprises cultivating a host cell as described above under conditions conducive to the production of the variant and recovering the variant from the cells and/or culture medium. [0135]
  • The medium used to cultivate the cells may be any conventional medium suitable for growing the host cell in question and obtaining expression of the alpha-amylase variant of the invention. Suitable media are available from commercial suppliers or may be prepared according to published recipes (e.g., as described in catalogues of the American Type Culture Collection). [0136]
  • The alpha-amylase variant secreted from the host cells may conveniently be recovered from the culture medium by well-known procedures, including separating the cells from the medium by centrifugation or filtration, and precipitating proteinaceous components of the medium by means of a salt such as ammonium sulphate, followed by the use of chromatographic procedures such as ion exchange chromatography, affinity chromatography, or the like. [0137]
  • Industrial Applications [0138]
  • The alpha-amylase variants of this invention possess valuable properties allowing for a variety of industrial applications. In particular, enzyme variants of the invention are applicable as a component in washing, dishwashing, and hard surface cleaning detergent compositions. [0139]

No. 3,912,590, EP patent publications Nos. 252 730 and 63 909, WO 99/19467, and WO 96/28567 all references hereby incorporated by reference). Also contemplated are compositions for starch conversion purposes, which may beside the variant of the invention also comprise a AMG, pullulanase, and other alpha-amylases. [0140]
  • Further, variants of the invention are also particularly useful in the production of sweeteners and ethanol (see, e.g., U.S. Pat. No. 5,231,017 hereby incorporated by reference), such as fuel, drinking and industrial ethanol, from starch or whole grains. [0141]
  • A variant of the invention may also be used for textile desizing (see, e.g., WO 95/21247, U.S. Pat. No. 4,643,736, EP 119,920 hereby in corporate by reference). [0142]
  • Detergent Compositions [0143]
  • As mentioned above, variants of the invention may suitably be incorporated in detergent compositions. Reference is made, for example, to WO 96/23874 and WO 97/07202 for further details concerning relevant ingredients of detergent compositions (such as laundry or dishwashing detergents), appropriate methods of formulating the variants in such detergent compositions, and for examples of relevant types of detergent compositions. [0144]
  • Detergent compositions comprising a variant of the invention may additionally comprise one or more other enzymes, such as a protease, a lipase, a peroxidase, another amylolytic enzyme, glucoamylase, maltogenic amylase, CGTase and/or a cellulase, mannanase (such as Mannaway™ from Novozymes, Denmark)), pectinase, pectine lyase, cutinase, laccase, and/or another alpha-amylase. [0145]
  • Alpha-amylase variants of the invention may be incorporated in detergents at conventionally employed concentrations. It is at present contemplated that a variant of the invention may be incorporated in an amount corresponding to 0.00001-10 mg (calculated as pure, active enzyme protein) of alpha-amylase per liter of wash/dishwash liquor using conventional dosing levels of detergent. [0146]

[0161]
  • Methods: [0162]
  • Low pH Filter Assay [0163]
  • [0164] Bacillus libraries are plated on a sandwich of cellulose acetate (OE 67, Schleicher & Schuell, Dassel, Germany)—and nitrocellulose filters (Protran-Ba 85, Schleicher & Schuell, Dassel, Germany) on TY agar plates with 10 micro g/ml chloramphenicol at 37° C. for at least 21 hours. The cellulose acetate layer is located on the TY agar plate.
  • Each filter sandwich is specifically marked with a needle after plating, but before incubation in order to be able to localize positive variants on the filter, and the nitrocellulose filter with bound variants is transferred to a container with citrate buffer, pH 4.5 and incubated at 80° C. for 20 minutes (when screening for variants in the wild type backbone) or 85° C. for 60 minutes (when screening for variants in the LE399 backbone). The cellulose acetate filters with colonies are stored on the TY-plates at room temperature until use. After incubation, residual activity is detected on assay plates containing 1% agarose, 0.2% starch in citrate buffer, pH 6.0. The assay plates with nitrocellulose filters are marked the same ay as the filter sandwich and incubated for 2 hours at 50° C. After removal of the filters the assay plates are stained with 10% Lugol solution. Starch degrading variants are detected as white spots on dark blue background and then identified on the storage plates. Positive variants are re-screened twice under the same conditions as the first screen. [0165]
  • Secondary Screening [0166]
  • Positive transformants after rescreening are picked from the storage plate and tested in a secondary plate assay. Positive transformants are grown for 22 hours at 37° C. in 5 ml LB+chloramphenicol. The Bacillus culture of each positive transformant and as a control a clone expressing the corresponding backbone are incubated in citrate buffer, pH 4.5 at 90° C. and samples are taken at 0, 10, 20, 30, 40, 60 and 80 minutes. A 3 micro liter sample is spotted on an assay plate. The assay plate is stained with 10% Lugol solution. Improved variants are seen as variants with higher residual activity (detected as halos on the assay plate) than the backbone. The improved variants are determined by nucleotide sequencing. [0167]
  • Stability Assay of Unpurified Variants: [0168]
  • Bacillus cultures expressing the variants to be analysed are grown for 21 hours at 37° C. in 10 ml LB+chloramphenicol. 800 micro liter culture is mixed with 200 micro 1 citrate buffer, pH 4.5. A number of 70 micro 1 aliquots corresponding to the number of sample time points are made in PCR tubes and incubated at 70° C. (for variants in the wt backbone) or 90° C. (for variants in LE399) for various time points (typically 5, 10, 15, 20, 25 and 30 minutes) in a PCR machine. The 0 min sample is not incubated at high temperature. Activity in the sample is measured by transferring 20 micro 1 to 200 micro 1 of the alpha-amylase PNP-G7 substrate MPR3 ((Boehringer Mannheim Cat. no. 1660730) as described below under “Assays for Alpha-Amylase Activity”. Results are plotted as percentage activity (relative to the 0 time point) versus time, or stated as percentage residual activity after incubation for a certain period of time. [0169]
  • Fermentation and Purification of Alpha-amylase Variants [0170]
  • A [0171] B. subtilis strain harbouring the relevant expression plasmid is streaked on a LB-agar plate with 10 micro g/ml kanamycin from −80° C. stock, and grown overnight at 37° C. The colonies are transferred to 100 ml PS-1 media supplemented with 10 micro g/ml chloamphinicol in a 500 ml shaking flask.
    Composition of PS-1 medium:
    Pearl sugar 100 g/l
    Soy Bean Meal 40 g/l
    Na2HPO4, 12 H2O 10 g/l
    PluronicTM PE 6100 0.1 g/l
    CaCO3 5 g/l
  • The culture is shaken at 37° C. at 270 rpm for 5 days. [0172]
  • Cells and cell debris are removed from the fermentation broth by centrifugation at 4500 rpm in 20-25 minutes. Afterwards the supernatant is filtered to obtain a completely clear solution. The filtrate is concentrated and washed on a UF-filter (10000 cut off membrane) and the buffer is changed to 20 mM Acetate pH 5.5. The UF-filtrate is applied on a S-sepharose F.F. and elution is carried out by step elution with 0.2M NaCl in the same buffer. The eluate is dialysed against 10 mM Tris, pH 9.0 and applied on a Q-sepharose F.F. and eluted with a linear gradient from 0-0.3M NaCl over 6 column volumes. The fractions that contain the activity (measured by the Phadebas assay) are pooled, pH was adjusted to pH 7.5 and remaining color was removed by a treatment with 0.5% W/vol. active coal in 5 minutes. [0173]
  • Stability Determination of Purified Variants [0174]
  • All stability trials of purified variants are made using the same set up. The method is as follows: The enzyme is incubated under the relevant conditions (1-4). Samples are taken at various time points, e.g., after 0, 5, 10, 15 and 30 minutes and diluted 25 times (same dilution for all taken samples) in assay buffer (0.1 M 50 mM Britton buffer pH 7.3) and the activity is measured using the Phadebas assay (Pharmacia) under standard conditions pH 7.3, 37° C. [0175]
  • The activity measured before incubation (0 minutes) is used as reference (100%). The decline in percent is calculated as a function of the incubation time. The table shows the residual activity after, e.g., 30 minutes of incubation. [0176]
  • Specific Activity Determination [0177]
  • The specific activity is determined using the Phadebas assay (Pharmacia) as activity/mg enzyme. The manufactures instructions are followed (see also below under “Assay for α-amylase activity). [0178]
  • Assays for Alpha-Amylase Activity [0179]
  • 1. Phadebas Assay [0180]
  • Alpha-amylase activity is determined by a method employing Phadebas® tablets as substrate. Phadebas tablets (Phadebas® a Amylase Test, supplied by Pharmacia Diagnostic) contain a cross-linked insoluble blue-colored starch polymer, which has been mixed with bovine serum albumin and a buffer substance and tabletted. [0181]
  • For every single measurement one tablet is suspended in a tube containing 5 ml 50 mM Britton-Robinson buffer (50 mM acetic acid, 50 mM phosphoric acid, 50 mM boric acid, 0.1 mM CaCl2, pH adjusted to the value of interest with NaOH). The test is performed in a water bath at the temperature of interest. The alpha-amylase to be tested is diluted in x ml of 50 mM Britton-Robinson buffer. 1 ml of this alpha-amylase solution is added to the 5 ml 50 mM Britton-Robinson buffer. The starch is hydrolyzed by the alpha-amylase giving soluble blue fragments. The absorbance of the resulting blue solution, measured spectrophotometrically at 620 nm, is a function of the alpha-amylase activity. [0182]
  • It is important that the measured 620 nm absorbance after 10 or 15 minutes of incubation (testing time) is in the range of 0.2 to 2.0 absorbance units at 620 nm. In this absorbance range there is linearity between activity and absorbance (Lambert-Beer law). The dilution of the enzyme must therefore be adjusted to fit this criterion. Under a specified set of conditions (temp., pH, reaction time, buffer conditions) 1 mg of a given alpha-amylase will hydrolyze a certain amount of substrate and a blue colour will be produced. The colour intensity is measured at 620 nm. The measured absorbance is directly proportional to the specific activity (activity/mg of pure alpha-amylase protein) of the alpha-amylase in question under the given set of conditions. [0183]
  • 2. Alternative Method [0184]
  • Alpha-amylase activity is determined by a method employing the PNP-G7 substrate. PNP-G7 which is a abbreviation for p-nitrophenyl-alpha, D-maltoheptaoside is a blocked oligosaccharide which can be cleaved by an endo-amylase. Following the cleavage, the alpha-Glucosidase included in the kit digest the substrate to liberate a free PNP molecule which has a yellow colour and thus can be measured by visible spectophometry at λ=405 nm (400-420 nm). Kits containing PNP-G7 substrate and alpha-Glucosidase is manufactured by Boehringer-Mannheim (cat. No.1054635). [0185]
  • To prepare the reagent solution 10 ml of substrate/buffer solution is added to 50 ml enzyme/buffer solution as recommended by the manufacturer. The assay is performed by transferring 20 micro 1 sample to a 96 well microtitre plate and incubating at 25° C. 200 micro 1 reagent solution pre-equilibrated to 25° C. is added. The solution is mixed and pre-incubated 1 minute and absorption is measured every 30 sec. over 4 minutes at OD 405 nm in an ELISA reader. [0186]
  • The slope of the time dependent absorption-curve is directly proportional to the activity of the alpha-amylase in question under the given set of conditions. [0187]
  • EXAMPLES Example 1
  • Construction, by error-prone PCR mutagenesis, of [0188] Bacillus licheniformis alpha-amylase variants having an improved stability at low pH, high temperature and low calcium ion concentration compared to the parent enzyme.
  • Error-prone PCR Mutagenesis and Library Construction [0189]
  • To improve the stability at low pH and low calcium concentration of the parent [0190] Bacillus licheniformis alpha-amylase, error-prone PCR mutagenesis was performed. The plasmid pDN1528 encoding the wild-type Bacillus licheniformis alpha-amylase gene was utilized as template to amplify this gene with primers: 22149: 5′-CGA TTG CTG ACG CTG TTA TTT GCG-3′ (SEQID NO: 14) and 24814: 5′-GAT CAC CCG CGA TAC CGT C-3′ (SEQ ID NO: 15) under PCR conditions where increased error rates leads to introduction of random point mutations. The PCR conditions utilized were: 10 mM Tris-HCl, pH 8.3, 50 mM KCl, 4 mM MgCl2, 0.3 mM MnCl2, 0.1 mM dGTP/dATP, 0.5 mM dTTP/dCTP, and 2.5 units Taq polymerase per 100 micro 1 reaction.
  • The resultant PCR fragment was purified on gel and used in a PCR-based multimerization step with a gel purified vector fragment created by PCR amplification of pDN1528 with primers #24: 5′-GAA TGT ATG TCG GCC GGC AAA ACG CCG GTG A-3′ (SEQ ID NO: 16) and #27: 5′-GCC GCC GCT GCT GCA GAA TGA GGC AGC AAG-3′ (SEQ ID NO:17) forming an overlap to the insert fragment. The multimerization reaction was subsequently introduced into [0191] B. subtilis (Shafikhani et al., Biotechniques, 23 (1997), 304-310).
  • Screening [0192]
  • The error-prone library described above was screened in the low pH filter assay (see “Materials & Methods”). Clones testing positive upon rescreening was submitted to secondary screening for stability in the liquid assay described in Materials and Methods. [0193]

  • Transfer, by site-directed mutagenesis, of a selection of mutations from Example 1 to a new (non-wild type) backbone to improve stability at low pH and low calcium ion concentration compared to the parent enzyme. [0198]
  • Site-directed Mutagenesis [0199]
  • Mutations from LE493 (K176R+D207V+Y402F) were transferred to LE399 yielding LE495. This was performed by the overlap PCR method (Kirchhoff and Desrosiers, PCR Methods and Applications, 2 (1993), 301-304). 2 overlapping PCR fragments were generated by amplification of the LE399 template with the primers: Fragment A: #312 Mut176 5′-CCC GAA AGC TGA ACC GCA TCT ATA GGT TTC AAG GGA AGA CTT GGG ATT-3′ (SEQ ID NO: 18) (mutated codon indicated in bold) and #290 D207overlap 5′-AGG ATG GTC ATA ATC AA GTC GG-3′ (SEQ ID NO: 19); Fragment B: #313 Mut207 5′-CCG ACT TTG ATT ATG ACC ATC CTG TTG TCG TAG CAG AGA TTA AGA GAT GGG G-3′ (SEQ ID NO: 20) and #314 Mut402 5′-CGA CAA TGT CAT GGT GGT CGA AAA AAT CAT GCT GTG CTC CGT ACG-3′ (SEQ ID NO: 21). Fragments A and B were mixed in equimolar ratios and subsequently the full-length fragment was amplified with the external primers: #312 Mut176 and #314 Mut402. This fragment was used in a multimerization reaction with the vector PCR fragment created with the primers #296 Y402 multi 5′-TTT CGA CCA CCA TGA CAT TGT CG-3′ (SEQ ID NO: 22) and #305 399Multi176 5′-TAT AGA TGC GGT TCA GCT TTC GGG-3′ (SEQ ID NO: 23) on template LE399 as described above. The multimerization reaction was subsequently transformed into [0200] B. subtilis. Clones were screened for stability in the assay mentioned above. The presence of the mutations from LE493 in several clones with increased stability was confirmed by sequencing.
  • LE 497 was obtained in a similar manner by amplifying the LE399 encoding template with primers #312 Mut176 and #314 Mut402 and using the resulting PCR fragment in a multimerization reaction with a vector fragment obtained by PCR amplification of the LE399 template with the primers #296 Y402multi and #305 399Multi176.
