Title: Compositions and methods for surface treatment with lipases

Description:
FIELD OF INVENTION 
     This invention relates to compositions comprising lipase enzymes and bleaching agents, as well as methods of making and using such compositions which are preferably fabric and home care products. 
     BACKGROUND OF THE INVENTION 
     Detergent manufacturers continue to try to provide cleaning compositions, particularly fabric and dish-cleaning compositions which provide the most robust cleaning systems. In the case of cleaning with lipase enzymes, they may be particularly vulnerable to oxidation, especially where such enzymes come into contact with bleach during storage or during a wash or treatment step, either both incorporated into the wash or treatment step, or one or the other component being carried over from a pre-treatment step, particularly for example from a pre-treating bleaching step. This leads to loss of activity or efficacy of the composition as a whole, and in particular to loss of enzyme activity. Certain bleach components are particularly problematic, such as pre-formed peracids and bleach catalysts or boosters. WO2007/001262 relates to cleaning compositions comprising organic catalysts with enhanced enzyme compatibility, specifically for amylase enzyme enhanced compatibility. There remains a need for a composition which alleviates this problem. 
     SUMMARY OF THE INVENTION 
     In accordance with the present invention there is provided a method of cleaning and/or treating a textile, hard surface and/or other surface for fabric and/or home care, comprising the steps of:
         a) contacting a textile, hard surface and/or other surface for fabric and/or home care with an aqueous solution comprising a lipase; and (ii) a bleach component and (iii) optional detergent adjunct;   b) rinsing and drying the textile or hard surface;
 
characterized in that the lipase has improved stability to oxidative degradation compared to the mature polypeptide of SEQ ID NO:1 and lipase activity, preferably the lipase variant comprises a lipase variant comprising a substitution at one or more of the positions selected from the group of positions corresponding to T37, N39 and G91, of the mature polypeptide of SEQ ID NO:1. The present invention also provides a method of manufacturing a detergent composition comprising a lipase variant exhibiting improved stability to oxidative degradation compared to the lipase variant of SEQ ID NO:1, and lipase activity, the method comprising the step of mixing the lipase variant with a detergent adjunct. Preferably the lipase variant is a variant of SEQ ID NO:1 comprising a substitution at one or more of the positions selected from the group of positions corresponding to T37, N39 and G91 of the mature polypeptide of SEQ ID NO:1. In accordance with a further aspect of the invention there is provided a composition comprising a lipase variant having lipase activity and exhibiting improved stability to oxidative degradation, and a detergent adjunct. The invention also provides a cleaning and/or treatment composition comprising a lipase variant having lipase activity and comprising a substitution at one or more of the positions selected from the group of positions corresponding to T37, N39 and G91 of the mature polypeptide of SEQ ID NO:1, and a detergent adjunct. It may be preferred that the compositions also comprise a bleach component.
       

     In accordance with a further aspect of the invention there is provided a method of manufacturing a detergent composition comprising a lipase and exhibiting improved stability to oxidative degradation, comprising the step of mixing a lipase variant comprising a substitution at one or more of the positions selected from the group of positions corresponding to T37, N39 and G91 of the mature polypeptide of SEQ ID NO:1, wherein the variant has lipase activity, with a detergent adjunct. 
     A lipase variant exhibiting improved stability to oxidative degradation can be determined by following the test in Example 1. Lipase variants exhibiting improved stability to oxidative degradation have a RPwash of at least 1.01, or at least 1.2 or even at least 1.5. The conventional lipase for comparison is that of SEQ ID NO:1.

The carrier material is finally washed three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C. 
     As used herein, the term “host cell” means any cell type that is susceptible to transformation, transfection, transduction, or the like with a nucleic acid construct or expression vector comprising a polynucleotide of the present invention. 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. 
     As used herein, the term “improved property” means a characteristic associated with a variant that is improved compared to the parent. Such improved properties includes improved performance in the presence of an organic catalyst. In some preferred embodiments, the invention relates to a composition or method in which the variant has improved stability to an organic catalyst selected from the group consisting of organic catalysts having the following formulae: 
                         
or
 
     c) mixtures thereof,

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:
 
(Identical Residues×100)/(Length of Alignment−Total Number of Gaps in Alignment)

     Conventions for Designation of Variants 
     For purposes of the present invention, the mature polypeptide disclosed in SEQ ID NO: 1 is used to determine the corresponding amino acid residue in another lipase. The amino acid sequence of another lipase is aligned with the mature polypeptide disclosed in SEQ ID NO: 1, and based on the alignment, the amino acid position number corresponding to any amino acid residue in the mature polypeptide disclosed in SEQ ID NO: 1 is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970 , J. Mol. Biol.  48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000 , Trends Genet.  16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. 
     Identification of the corresponding amino acid residue in another lipase can be determined by an alignment of multiple polypeptide sequences using several computer programs including, but not limited to, MUSCLE (multiple sequence comparison by log-expectation; version 3.5 or later; Edgar, 2004 , Nucleic Acids Research  32: 1792-1797), MAFFT (version 6.857 or later; Katoh and Kuma, 2002 , Nucleic Acids Research  30: 3059-3066; Katoh et al., 2005 , Nucleic Acids Research  33: 511-518; Katoh and Toh, 2007 , Bioinformatics  23: 372-374; Katoh et al., 2009 , Methods in Molecular Biology  537: 39-64; Katoh and Toh, 2010 , Bioinformatics  26: 1899-1900), and EMBOSS EMMA employing ClustalW (1.83 or later; Thompson et al., 1994 , Nucleic Acids Research  22: 4673-4680), using their respective default parameters. 
     When the other enzyme has diverged from the mature polypeptide of SEQ ID NO: 1 such that traditional sequence-based comparison fails to detect their relationship (Lindahl and Elofsson, 2000 , J. Mol. Biol.  295: 613-615), other pairwise sequence comparison algorithms can be used. Greater sensitivity in sequence-based searching can be attained using search programs that utilize probabilistic representations of polypeptide families (profiles) to search databases. For example, the PSI-BLAST program generates profiles through an iterative database search process and is capable of detecting remote homologs (Atschul et al., 1997 , Nucleic Acids Res.  25: 3389-3402). Even greater sensitivity can be achieved if the family or superfamily for the polypeptide has one or more representatives in the protein structure databases. Programs such as GenTHREADER (Jones, 1999 , J. Mol. Biol.  287: 797-815; McGuffin and Jones, 2003 , Bioinformatics  19: 874-881) utilize information from a variety of sources (PSI-BLAST, secondary structure prediction, structural alignment profiles, and solvation potentials) as input to a neural network that predicts the structural fold for a query sequence. Similarly, the method of Gough et al., 2000 , J. Mol. Biol.  313: 903-919, can be used to align a sequence of unknown structure with the superfamily models present in the SCOP database. These alignments can in turn be used to generate homology models for the polypeptide, and such models can be assessed for accuracy using a variety of tools developed for that purpose. 
     For proteins of known structure, several tools and resources are available for retrieving and generating structural alignments. For example the SCOP superfamilies of proteins have been structurally aligned, and those alignments are accessible and downloadable. Two or more protein structures can be aligned using a variety of algorithms such as the distance alignment matrix (Holm and Sander, 1998 , Proteins  33: 88-96) or combinatorial extension (Shindyalov and Bourne, 1998 , Protein Engineering  11: 739-747), and implementation of these algorithms can additionally be utilized to query structure databases with a structure of interest in order to discover possible structural homologs (e.g., Holm and Park, 2000 , Bioinformatics  16: 566-567). 
     In describing the variants of the present invention, the nomenclature described below is adapted for ease of reference. The accepted IUPAC single letter or three letter amino acid abbreviations are employed. 
     Substitutions. 
     For an amino acid substitution, the following nomenclature is used: 
     Original amino acid, position, substituted amino acid. Accordingly, the substitution of threonine at position 226 with alanine is designated as “Thr226Ala” or “T226A”. Multiple mutations are separated by addition marks (“+”), e.g., “Gly205Arg+Ser411Phe” or “G205R+S411F”, representing substitutions at positions 205 and 411 of glycine (G) with arginine (R) and serine (S) with phenylalanine (F), respectively. 
     Multiple Substitutions. 
     Variants comprising multiple substitutions are separated by addition marks (“+”), e.g., “Arg170Tyr+Gly195Glu” or “R170Y+G195E” representing a substitution of arginine and glycine at positions 170 and 195 with tyrosine and glutamic acid, respectively. 
     Different Substitutions. 
     Where different alterations can be introduced at a position, the different alterations are separated by a comma, e.g., “Arg170Tyr,Glu” or “R170Y,E” represents a substitution of arginine at position 170 with tyrosine or glutamic acid. Thus, “Tyr167Gly,Ala+Arg170Gly,Ala” designates the following variants: “Tyr167Gly+Arg170Gly”, “Tyr167Gly+Arg170Ala”, “Tyr167Ala+Arg170Gly”, and “Tyr167Ala+Arg170Ala”. 
     Lipase Variants 
     In order to assess the stability to oxidative degradation of the lipase variant, the value for Relative Performance (RPwash) is determined, i.e. wash performance (P) of the lipase variant to be tested, and divided by the wash performance of the lipase of SEQ ID NO:1. Thus RPwash=P(invention lipase variant)/P(SEQ ID NO:1 lipase). Lipase variants having improved stability to oxidative degradation will have a RPwash value at least 1.01, preferably at least 1.1, or even at least 1.5. 
     A lipase variant suitable for use in the present invention comprises a substitution at one or more of the positions selected from the group of positions corresponding to T37, N39 and G91. Preferably the lipase variant is an isolated lipase variant. Suitable lipase variants for use in the present invention preferably comprise a substitution at one or more (e.g., several) positions corresponding to positions T37A,D,E,F,G,H,I,L,N,P,Q,R,S,V,W,Y, N39A,C,D,E,F,G,I,K,L,M,P,Q,R,T,V,W,Y, and G91D,H,I,P,Q or even G91A of the mature polypeptide of SEQ ID NO: 1, wherein the variant has lipase activity.

     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). 
     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. 
     For example, the variants may comprise a substitution at a position corresponding to positions D96, T143, A150, E210, G225, T231, N233 and P250 of the mature polypeptide of SEQ ID NO: 1. In some embodiments the substitution is selected from D96G, T143A, A150G, E210Q, G225R, T231R, N233R and P250R.

     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 mutant molecules are tested for lipase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 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 et al., 1992 , Science  255: 306-312; Smith et al., 1992 , J. Mol. Biol.  224: 899-904; Wlodaver et al., 1992 , FEBS Lett.  309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide. 
     The variants may consist of at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, and at least 95% of the number of amino acids of the mature polypeptide. 
     In an embodiment, the variant has improved performance, in particular in the presence of a bleach component. Preferred variants have improved performance in the presence of an organic catalyst selected from the group consisting of organic catalysts having the following formulae: 
                         
or
 
     c) mixtures thereof, 
     mixtures thereof, wherein each R1 is independently a branched alkyl group containing from 3 to 24 carbons or a linear alkyl group containing from 1 to 24 carbons; and recovering the variant. 
     In some embodiments R1 is independently a branched alkyl group containing from 8 to 18 carbons or a linear alkyl group containing from 8 to 18 carbons. 
     In some embodiments R1 is independently selected from the group consisting of 2-propylheptyl, 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, n-dodecyl, n-tetradecyl, n-hexadecyl, n-octadecyl, iso-nonyl, iso-decyl, iso-tridecyl, and iso-pantadecyl. Preferably R1 is selected from the group consisting of 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, iso-tridecyl, and iso-pantadecyl. Preferred variants have improved performance in the presence of a catalyst of formula b) in which R is 2-butyloctyl. 
     Parent Lipases 
     The parent lipase may be a polypeptide having at least 60% sequence identity to the mature polypeptide of SEQ ID NO: 1. 
     In an aspect, the parent has a sequence identity to the mature polypeptide of SEQ ID NO: 1 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%, which have lipase activity. In one aspect, the amino acid sequence of the parent differs by no more than 20 amino acids, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 from the mature polypeptide of SEQ ID NO: 1. 
     In another aspect, the parent comprises or consists of the amino acid sequence of SEQ ID NO: 1. In another aspect, the parent comprises or consists of the mature polypeptide of SEQ ID NO: 1. In another aspect, the parent comprises or consists of amino acids 1 to 269 of SEQ ID NO: 1. 
     In another aspect, the parent is a fragment of the mature polypeptide of SEQ ID NO: 1 containing at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, and at least 95% of the number of amino acids of the mature polypeptide. 
     In another embodiment, the parent is an allelic variant of the mature polypeptide of SEQ ID NO: 1. 
     The polypeptide of SEQ ID NO: 1 or a fragment thereof, may be used to design nucleic acid probes to identify and clone DNA encoding a parent 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  32 P,  3 H,  35 S, 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 parent. 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. 
     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 parent 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 such as 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 et al., 1993 , EMBO J.  12: 2575-2583; Dawson et al., 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 et al., 2000,  J. Biotechnol.  76: 245-251; Rasmussen-Wilson et al., 1997,  Appl. Environ. Microbiol.  63: 3488-3493; Ward et al., 1995,  Biotechnology  13: 498-503; and Contreras et al., 1991,  Biotechnology  9: 378-381; Eaton et al., 1986,  Biochemistry  25: 505-512; Collins-Racie et al., 1995,  Biotechnology  13: 982-987; Carter et al., 1989,  Proteins: Structure, Function, and Genetics  6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.

     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 and Zellkulturen GmbH (DSMZ), Centraalbureau Voor Schimmelcultures (CBS), and Agricultural Research Service Patent Culture Collection, Northern Regional Research Center (NRRL).

A polynucleotide encoding a parent 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 parent 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 et al., 1989, supra). 
     Preparation of Variants 
     The present invention also relates to a method for obtaining a lipase variant, comprising introducing into a parent lipase a substitution at one or more positions corresponding to positions T37, N39, or G91 of the mature polypeptide of SEQ ID NO: 1, wherein the variant has lipase activity and in comparison with the parent lipase has improved performance in the presence of an organic catalyst selected from the group consisting of organic catalysts having the following formulae: 
                         
or (c) mixtures thereof, wherein each R1 is independently a branched alkyl group containing from 3 to 24 carbons or a linear alkyl group containing from 1 to 24 carbons; and recovering the variant.
 
     In some embodiments the invention relates to a method wherein R1 is independently a branched alkyl group containing from 8 to 18 carbons or a linear alkyl group containing from 8 to 18 carbons. 
     In some embodiments the invention relates to a method wherein R1 is independently selected from the group consisting of 2-propylheptyl, 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, n-dodecyl, n-tetradecyl, n-hexadecyl, n-octadecyl, iso-nonyl, iso-decyl, iso-tridecyl, and iso-pantadecyl. Preferably R1 is selected from the group consisting of 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, iso-tridecyl, and iso-pantadecyl. 
     The organic catalyst is typically used in an amount which provides 0.001-0.02 g of active material per liter of wash liquor or in an amount which provides 0.01 to 4.5, 0.5 to 4.0, 1.0 to 3.5, 1.5 to 3.0, or 2.0 to 2.5 ppm of active material per liter of wash liquor. 
     In some embodiments the invention relates to a method wherein a source of organic peroxyacids is present as a bleaching agent. The source of organic peroxyacids may be a preformed peracid or a diacyl peroxide, or it may comprise a source of hydrogen peroxide and a bleach activator. 
     Suitable bleaching agents include diacyl peroxides, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, pre-formed peracids and mixtures thereof. 
     In general, when a bleaching agent is used, the compositions of the present invention may comprise from about 0.1% to about 50% or even from about 0.1% to about 25% bleaching agent by weight of the subject cleaning composition. The bleaching agent is typically a source of organic peroxyacids or an activated peroxygen source. 
     When present, the peracid and/or bleach activator is generally present in the composition in an amount of from about 0.1 to about 60 wt %, from about 0.5 to about 40 wt % or even from about 0.6 to about 10 wt % based on the composition. One or more hydrophobic peracids or precursors thereof may be used in combination with one or more hydrophilic peracid or precursor thereof. 
     The amounts of hydrogen peroxide source and peracid or bleach activator may be selected such that the molar ratio of available oxygen (from the peroxide source) to peracid is from 1:1 to 35:1, or even 2:1 to 10:1. 
     In some embodiments the invention relates to a method wherein the parent lipase comprises an amino acid sequence with at least 60% identity with the mature polypeptide of SEQ ID NO: 1; consists of the amino acid sequence of the mature polypeptide of SEQ ID NO: 1, or a fragment thereof having lipase activity. 
     In some embodiments the invention relates to a method wherein the variant is: (a) a polypeptide comprising an amino acid sequence with at least 60% identity with the mature polypeptide of SEQ ID NO: 1; (b) a polypeptide encoded by a polynucleotide that hybridizes under at least low stringency conditions with: (i) the mature polypeptide coding sequence of SEQ ID NO: 1; or (ii) a full-length complementary strand of (i), or (c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 60% identity with the mature polypeptide coding sequence of SEQ ID NO: 1.

     In some embodiments the invention relates to a method wherein the substitution is selected from D96G, T143A, A150G, E210Q, G225R, T231R, N233R and P250R. 
     The variants can be prepared using any mutagenesis procedure known in the art, such as site-directed mutagenesis, synthetic gene construction, semi-synthetic gene construction, random mutagenesis, shuffling, etc. 
     Site-directed mutagenesis is a technique in which one or more (e.g., several) mutations are introduced at one or more defined sites in a polynucleotide encoding the parent. 
     Site-directed mutagenesis can be accomplished in vitro by PCR involving the use of oligonucleotide primers containing the desired mutation. Site-directed mutagenesis can also be performed in vitro by cassette mutagenesis involving the cleavage by a restriction enzyme at a site in the plasmid comprising a polynucleotide encoding the parent and subsequent ligation of an oligonucleotide containing the mutation in the polynucleotide. Usually the restriction enzyme that digests the plasmid and the oligonucleotide is the same, permitting sticky ends of the plasmid and the insert to ligate to one another. See, e.g., Scherer and Davis, 1979 , Proc. Natl. Acad. Sci. USA  76: 4949-4955; and Barton et al., 1990,  Nucleic Acids Res.  18: 7349-4966. 
     Site-directed mutagenesis can also be accomplished in vivo by methods known in the art. See, e.g., U.S. Patent Application Publication No. 2004/0171154; Storici et al., 2001,  Nature Biotechnol.  19: 773-776; Kren et al., 1998,  Nat. Med.  4: 285-290; and Calissano and Macino, 1996 , Fungal Genet. Newslett.  43: 15-16. 
     Any site-directed mutagenesis procedure can be used in the present invention. There are many commercial kits available that can be used to prepare variants. 
     Synthetic gene construction entails in vitro synthesis of a designed polynucleotide molecule to encode a polypeptide of interest. Gene synthesis can be performed utilizing a number of techniques, such as the multiplex microchip-based technology described by Tian et al. (2004 , Nature  432: 1050-1054) and similar technologies wherein oligonucleotides are synthesized and assembled upon photo-programmable microfluidic chips. 
     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 display (e.g., Lowman et al., 1991 , Biochemistry  30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204) and region-directed mutagenesis (Derbyshire et al., 1986 , Gene  46: 145; Ner et al., 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 et al., 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. 
     Semi-synthetic gene construction is accomplished by combining aspects of synthetic gene construction, and/or site-directed mutagenesis, and/or random mutagenesis, and/or shuffling. Semi-synthetic construction is typified by a process utilizing polynucleotide fragments that are synthesized, in combination with PCR techniques. Defined regions of genes may thus be synthesized de novo, while other regions may be amplified using site-specific mutagenic primers, while yet other regions may be subjected to error-prone PCR or non-error prone PCR amplification. Polynucleotide subsequences may then be shuffled. 
     Polynucleotides 
     Also disclosed herein are isolated polynucleotides encoding a variant of the present invention. 
     Nucleic Acid Constructs 
     Also disclosed herein are nucleic acid constructs comprising a polynucleotide encoding a variant 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 a variant. 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 which is recognized by a host cell for expression of the polynucleotide. The promoter contains transcriptional control sequences that mediate the expression of the variant.

     Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in a filamentous fungal host cell are promoters obtained from the genes for  Aspergillus nidulans  acetamidase,  Aspergillus niger  neutral alpha-amylase,  Aspergillus niger  acid stable alpha-amylase,  Aspergillus niger  or  Aspergillus awamori  glucoamylase (glaA),  Aspergillus oryzae  TAKA amylase,  Aspergillus oryzae  alkaline protease,  Aspergillus oryzae  triose phosphate isomerase,  Fusarium oxysporum  trypsin-like protease (WO 96/00787),  Fusarium venenatum  amyloglucosidase (WO 00/56900),  Fusarium venenatum  Daria (WO 00/56900),  Fusarium venenatum  Quinn (WO 00/56900),  Rhizomucor miehei  lipase,  Rhizomucor miehei  aspartic proteinase,  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 IV,  Trichoderma reesei  endoglucanase V,  Trichoderma reesei  xylanase I,  Trichoderma reesei  xylanase II,  Trichoderma reesei  beta-xylosidase, as well as the NA2-tpi promoter (a modified promoter from an  Aspergillus neutral  alpha-amylase gene in which the untranslated leader has been replaced by an untranslated leader from an  Aspergillus  triose phosphate isomerase gene; non-limiting examples include modified promoters from an  Aspergillus niger  neutral alpha-amylase gene in which the untranslated leader has been replaced by an untranslated leader from an  Aspergillus nidulans  or  Aspergillus oryzae  triose phosphate isomerase gene); and mutant, truncated, and hybrid promoters thereof. 
     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 et al., 1992 , Yeast  8: 423-488. 
     The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator sequence is operably linked to the 3′-terminus of the polynucleotide encoding the variant. Any terminator that is functional in the host cell may be used. 
     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  anthranilate synthase,  Aspergillus niger glucoamylase, Aspergillus niger  alpha-glucosidase,  Aspergillus oryzae  TAKA amylase, and  Fusarium oxysporum  trypsin-like protease. 
     Preferred terminators for yeast host cells are obtained from the genes for  Saccharomyces cerevisiae  enolase,  Saccharomyces cerevisiae  cytochrome C (CYC1), and  Saccharomyces cerevisiae  glyceraldehyde-3-phosphate dehydrogenase. 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  cryIIIA gene (WO 94/25612) and a  Bacillus subtilis  SP82 gene (Hue et al., 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 sequence is operably linked to the 5′-terminus of the polynucleotide encoding the variant. 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 variant-encoding sequence 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 variant and directs the variant into the cell&#39;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 variant. 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 variant. However, any signal peptide coding sequence that directs the expressed variant 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 11837 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 variant. 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 the variant 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 variant relative to the growth of the host cell. Examples of regulatory systems 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 systems in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GALL system may be used. In filamentous fungi, the  Aspergillus niger  glucoamylase promoter,  Aspergillus oryzae  TAKA alpha-amylase promoter, and  Aspergillus oryzae  glucoamylase 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 variant would be operably linked with the regulatory sequence. 
     Expression Vectors 
     The present invention also relates to recombinant expression vectors comprising a polynucleotide encoding a variant 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 variant 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, 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. 
     The vector preferably contains an element(s) that permits integration of the vector into the host cell&#39;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&#39;s sequence encoding the variant 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 pAMB1 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 ANS1 (Gems et al., 1991 , Gene  98: 61-67; Cullen et al., 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 variant. 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 invention also relates to recombinant host cells, comprising a polynucleotide encoding a variant of the present invention operably linked to one or more control sequences that direct the production of a variant of the present invention. 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 variant and its source. 
     The host cell may be any cell useful in the recombinant production of a variant, e.g., a prokaryote or a eukaryote. 
     The prokaryotic host cell may be any Gram-positive or Gram-negative bacterium. Gram-positive bacteria include, but are not limited to,  Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus , and  Streptomyces . Gram-negative bacteria include, but are not limited to,  Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella , and  Ureaplasma.    
     The bacterial host cell may be any  Bacillus  cell including, but not limited to,  Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, Bacillus subtilis , and  Bacillus thuringiensis  cells. 
     The bacterial host cell may also be any  Streptococcus  cell including, but not limited to,  Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis , and  Streptococcus equi  subsp.  Zooepidemicus  cells. 
     The bacterial host cell may also be any  Streptomyces  cell, including, but not limited to,  Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus , and  Streptomyces lividans  cells. 
     The introduction of DNA into a  Bacillus  cell may be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979 , Mol. Gen. Genet.  168: 111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961 , J. Bacteriol.  81: 823-829, or Dubnau and Davidoff-Abelson, 1971 , J. Mol. Biol.  56: 209-221), electroporation (see, e.g., Shigekawa and Dower, 1988 , Biotechniques  6: 742-751), or conjugation (see, e.g., Koehler and Thorne, 1987 , J. Bacteriol.  169: 5271-5278). 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 al., 2004,  Folia Microbiol . ( Praha ) 49: 399-405), conjugation (see, e.g., Mazodier et al., 1989,  J. Bacteriol.  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 introduction of DNA into a  Streptococcus  cell may be effected by natural competence (see, e.g., Perry and Kuramitsu, 1981 , Infect. Immun.  32: 1295-1297), protoplast transformation (see, e.g., Catt and Jollick, 1991 , Microbios  68: 189-207), electroporation (see, e.g., Buckley et al., 1999,  Appl. Environ. Microbiol.  65: 3800-3804) or conjugation (see, e.g., Clewell, 1981 , Microbiol. Rev.  45: 409-436). However, any method known in the art for introducing DNA into a host cell can be used. 
     The host cell may also be a eukaryote, such as a mammalian, insect, plant, or fungal cell. 
     The host cell may be a fungal cell. “Fungi” as used herein includes the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota as well as the Oomycota and all mitosporic fungi (as defined by Hawksworth et al.,  In, Ainsworth and Bisby&#39;s Dictionary of The Fungi,  8th edition, 1995, CAB International, University Press, Cambridge, UK). 
     The fungal host cell may be a yeast cell. “Yeast” as used herein includes ascosporogenous yeast (Endomycetales), basidiosporogenous yeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes). Since the classification of yeast may change in the future, for the purposes of this invention, yeast shall be defined as described in  Biology and Activities of Yeast  (Skinner, Passmore, and Davenport, editors,  Soc. App. Bacteriol. Symposium Series No.  9, 1980). 
     The yeast host cell may be a  Candida, Hansenula, Kluyveromyces, Pichia, Saccharomyces, Schizosaccharomyces , or  Yarrowia  cell such as a  Kluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomyces cerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii, Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomyces oviformis , or  Yarrowia lipolytica  cell. 
     The fungal host cell may be a filamentous fungal cell. “Filamentous fungi” include all filamentous forms of the subdivision Eumycota and Oomycota (as defined by Hawksworth et al., 1995, supra). The filamentous fungi are generally characterized by a mycelial wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth is by hyphal elongation and carbon catabolism is obligately aerobic. In contrast, vegetative growth by yeasts such as  Saccharomyces cerevisiae  is by budding of a unicellular thallus and carbon catabolism may be fermentative. 
     The filamentous fungal host cell may be an  Acremonium, Aspergillus, Aureobasidium, Bjerkandera, Ceriporiopsis, Chrysosporium, Coprinus, Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe, Mucor, Myceliophthora, Neocallimastix, Neurospora, Paecilomyces, Penicillium, Phanerochaete, Phlebia, Piromyces, Pleurotus, Schizophyllum, Talaromyces, Thermoascus, Thielavia, Tolypocladium, Trametes , or  Trichoderma  cell. 
     For example, the filamentous fungal host cell may be an  Aspergillus awamori, Aspergillus foetidus, Aspergillus fumigatus, Aspergillus japonicus, Aspergillus nidulans, Aspergillus niger, Aspergillus oryzae, Bjerkandera adusta, Ceriporiopsis aneirina, Ceriporiopsis caregiea, Ceriporiopsis gilvescens, Ceriporiopsis pannocinta, Ceriporiopsis rivulosa, Ceriporiopsis subrufa, Ceriporiopsis subvermispora, Chrysosporium mops, Chrysosporium keratinophilum, Chrysosporium lucknowense, Chrysosporium merdarium, Chrysosporium pannicola, Chrysosporium queenslandicum, Chrysosporium tropicum, Chrysosporium zonatum, Coprinus cinereus, Coriolus hirsutus, Fusarium bactridioides, Fusarium cerealis, Fusarium crookwellense, Fusarium culmorum, Fusarium graminearum, Fusarium graminum, Fusarium heterosporum, Fusarium negundi, Fusarium oxysporum, Fusarium reticulatum, Fusarium roseum, Fusarium sambucinum, Fusarium sarcochroum, Fusarium sporotrichioides, Fusarium sulphureum, Fusarium torulosum, Fusarium trichothecioides, Fusarium venenatum, Humicola insolens, Humicola lanuginosa, Mucor miehei, Myceliophthora thermophila, Neurospora crassa, Penicillium purpurogenum, Phanerochaete chrysosporium, Phlebia radiata, Pleurotus eryngii, Thielavia terrestris, Trametes villosa, Trametes versicolor, Trichoderma harzianum, Trichoderma koningii, Trichoderma longibrachiatum, Trichoderma reesei , or  Trichoderma viride  cell. 
     Fungal cells may be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a manner known per se. Suitable procedures for transformation of  Aspergillus  and  Trichoderma  host cells are described in EP 238023, Yelton et al., 1984 , Proc. Natl. Acad. Sci. USA  81: 1470-1474, and Christensen et al., 1988 , Bio/Technology  6: 1419-1422. Suitable methods for transforming  Fusarium  species are described by Malardier et al., 1989 , Gene  78: 147-156, and WO 96/00787. Yeast may be transformed using the procedures described by Becker and Guarente, In Abelson, J. N. and Simon, M. I., editors,  Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology , Volume 194, pp 182-187, Academic Press, Inc., New York; Ito et al., 1983 , J. Bacteriol.  153: 163; and Hinnen et al., 1978 , Proc. Natl. Acad. Sci. USA  75: 1920. 
     Methods of Production 
     Also disclosed herein are methods of producing a variant, comprising: (a) cultivating a host cell of the present invention under conditions suitable for expression of the variant; and (b) recovering the variant. 
     The host cells are cultivated in a nutrient medium suitable for production of the variant using methods known in the art. For example, the cell may be cultivated by shake flask cultivation, or small-scale or large-scale fermentation (including continuous, batch, fed-batch, or solid state fermentations) in laboratory or industrial fermentors performed in a suitable medium and under conditions allowing the variant to be expressed and/or isolated. The cultivation takes place in a suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts, using procedures known in the art. Suitable media are available from commercial suppliers or may be prepared according to published compositions (e.g., in catalogues of the American Type Culture Collection). If the variant is secreted into the nutrient medium, the variant can be recovered directly from the medium. If the variant is not secreted, it can be recovered from cell lysates. 
     The variant may be detected using methods known in the art that are specific for the variants. These detection methods include, but are not limited to, use of specific antibodies, formation of an enzyme product, or disappearance of an enzyme substrate. For example, an enzyme assay may be used to determine the activity of the variant. 
     The variant may be recovered using methods known in the art. For example, the variant may be recovered from the nutrient medium by conventional procedures including, but not limited to, collection, centrifugation, filtration, extraction, spray-drying, evaporation, or precipitation. 
     The variant may be purified by a variety of procedures known in the art including, but not limited to, chromatography (e.g., ion exchange, affinity, hydrophobic, chromatofocusing, and size exclusion), electrophoretic procedures (e.g., preparative isoelectric focusing), differential solubility (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, e.g.,  Protein Purification , Janson and Ryden, editors, VCH Publishers, New York, 1989) to obtain substantially pure variants. 
     In an alternative aspect, the variant is not recovered, but rather a host cell of the present invention expressing the variant is used as a source of the variant.

Examples of suitable lipophilic fluids include siloxanes, other silicones, hydrocarbons, glycol ethers, glycerine derivatives such as glycerine ethers, perfluorinated amines, perfluorinated and hydrofluoroether solvents, low-volatility nonfluorinated organic solvents, diol solvents, other environmentally-friendly solvents and mixtures thereof. 
     Structurant/Thickeners 
     Structured liquids can either be internally structured, whereby the structure is formed by primary ingredients (e.g. surfactant material) and/or externally structured by providing a three dimensional matrix structure using secondary ingredients (e.g. polymers, clay and/or silicate material). The composition may comprise a structurant, preferably from 0.01 wt % to 5 wt %, from 0.1 wt % to 2.0 wt % structurant. The structurant is typically selected from the group consisting of diglycerides and triglycerides, ethylene glycol distearate, microcrystalline cellulose, cellulose-based materials, microfiber cellulose, hydrophobically modified alkali-swellable emulsions such as Polygel W30 (3VSigma), biopolymers, xanthan gum, gellan gum, and mixtures thereof. A suitable structurant includes hydrogenated castor oil, and non-ethoxylated derivatives thereof. A suitable structurant is disclosed in U.S. Pat. No. 6,855,680. Such structurants have a thread-like structuring system having a range of aspect ratios. Other suitable structurants and the processes for making them are described in WO2010/034736. 
     Conditioning Agents 
     The composition of the present invention may include a high melting point fatty compound. The high melting point fatty compound useful herein has a melting point of 25° C. or higher, and is selected from the group consisting of fatty alcohols, fatty acids, fatty alcohol derivatives, fatty acid derivatives, and mixtures thereof. Such compounds of low melting point are not intended to be included in this section. Non-limiting examples of the high melting point compounds are found in International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, and CTFA Cosmetic Ingredient Handbook, Second Edition, 1992. 
     The high melting point fatty compound is included in the composition at a level of from about 0.1% to about 40%, preferably from about 1% to about 30%, more preferably from about 1.5% to about 16% by weight of the composition, from about 1.5% to about 8% in view of providing improved conditioning benefits such as slippery feel during the application to wet hair, softness and moisturized feel on dry hair. 
     The compositions of the present invention may contain a cationic polymer. Concentrations of the cationic polymer in the composition typically range from about 0.05% to about 3%, in another embodiment from about 0.075% to about 2.0%, and in yet another embodiment from about 0.1% to about 1.0%. Suitable cationic polymers will have cationic charge densities of at least about 0.5 meq/gm, in another embodiment at least about 0.9 meq/gm, in another embodiment at least about 1.2 meq/gm, in yet another embodiment at least about 1.5 meq/gm, but in one embodiment also less than about 7 meq/gm, and in another embodiment less than about 5 meq/gm, at the pH of intended use of the composition, which pH will generally range from about pH 3 to about pH 9, in one embodiment between about pH 4 and about pH 8. Herein, “cationic charge density” of a polymer refers to the ratio of the number of positive charges on the polymer to the molecular weight of the polymer. The average molecular weight of such suitable cationic polymers will generally be between about 10,000 and 10 million, in one embodiment between about 50,000 and about 5 million, and in another embodiment between about 100,000 and about 3 million. 
     Suitable cationic polymers for use in the compositions of the present invention contain cationic nitrogen-containing moieties such as quaternary ammonium or cationic protonated amino moieties. Any anionic counterions can be used in association with the cationic polymers so long as the polymers remain soluble in water, in the composition, or in a coacervate phase of the composition, and so long as the counterions are physically and chemically compatible with the essential components of the composition or do not otherwise unduly impair product performance, stability or aesthetics. Nonlimiting examples of such counterions include halides (e.g., chloride, fluoride, bromide, iodide), sulfate and methylsulfate. 
     Nonlimiting examples of such polymers are described in the CTFA Cosmetic Ingredient Dictionary, 3rd edition, edited by Estrin, Crosley, and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C. (1982)). 
     Other suitable cationic polymers for use in the composition include polysaccharide polymers, cationic guar gum derivatives, quaternary nitrogen-containing cellulose ethers, synthetic polymers, copolymers of etherified cellulose, guar and starch. When used, the cationic polymers herein are either soluble in the composition or are soluble in a complex coacervate phase in the composition formed by the cationic polymer and the anionic, amphoteric and/or zwitterionic surfactant component described hereinbefore. Complex coacervates of the cationic polymer can also be formed with other charged materials in the composition. 
     Suitable cationic polymers are described in U.S. Pat. Nos. 3,962,418; 3,958,581; and U.S. Publication No. 2007/0207109A1, which are all. 
     The composition of the present invention may include a nonionic polymer as a conditioning agent. Polyalkylene glycols having a molecular weight of more than about 1000 are useful herein. Useful are those having the following general formula: 
     
       
         
         
             
             
         
       
     
     wherein R 95  is selected from the group consisting of H, methyl, and mixtures thereof. Conditioning agents, and in particular silicones, may be included in the composition. The conditioning agents useful in the compositions of the present invention typically comprise a water insoluble, water dispersible, non-volatile, liquid that forms emulsified, liquid particles. Suitable conditioning agents for use in the composition are those conditioning agents characterized generally as silicones (e.g., silicone oils, cationic silicones, silicone gums, high refractive silicones, and silicone resins), organic conditioning oils (e.g., hydrocarbon oils, polyolefins, and fatty esters) or combinations thereof, or those conditioning agents which otherwise form liquid, dispersed particles in the aqueous surfactant matrix herein. Such conditioning agents should be physically and chemically compatible with the essential components of the composition, and should not otherwise unduly impair product stability, aesthetics or performance. 
     The concentration of the conditioning agent in the composition should be sufficient to provide the desired conditioning benefits. Such concentration can vary with the conditioning agent, the conditioning performance desired, the average size of the conditioning agent particles, the type and concentration of other components, and other like factors. 
     The concentration of the silicone conditioning agent typically ranges from about 0.01% to about 10%. Non-limiting examples of suitable silicone conditioning agents, and optional suspending agents for the silicone, are described in U.S. Reissue Pat. No. 34,584, U.S. Pat. Nos. 5,104,646; 5,106,609; 4,152,416; 2,826,551; 3,964,500; 4,364,837; 6,607,717; 6,482,969; 5,807,956; 5,981,681; 6,207,782; 7,465,439; 7,041,767; 7,217,777; US Patent Application Nos. 2007/0286837A1; 2005/0048549A1; 2007/0041929A1; British Pat.

(1984); and in Encyclopedia of Polymer Science and Engineering, vol. 15, 2d ed., pp 204-308, John Wiley &amp; Sons, Inc. (1989). 
     The compositions of the present invention may also comprise from about 0.05% to about 3% of at least one organic conditioning oil as the conditioning agent, either alone or in combination with other conditioning agents, such as the silicones (described herein). Suitable conditioning oils include hydrocarbon oils, polyolefins, and fatty esters. Also suitable for use in the compositions herein are the conditioning agents described by the Procter &amp; Gamble Company in U.S. Pat. Nos. 5,674,478, and 5,750,122. Also suitable for use herein are those conditioning agents described in U.S. Pat. Nos. 4,529,586, 4,507,280, 4,663,158, 4,197,865, 4,217, 914, 4,381,919, and 4,422, 853. 
     Hygiene and malodour—The compositions of the present invention may also comprise one or more of zinc ricinoleate, thymol, quaternary ammonium salts such as Bardac®, polyethylenimines (such as Lupasol® from BASF) and zinc complexes thereof, silver and silver compounds, especially those designed to slowly release Ag +  or nano-silver dispersions.

     Suds Boosters—If high sudsing is desired, suds boosters such as the C 10 -C 16  alkanolamides or C 10 -C 14  alkyl sulphates can be incorporated into the compositions, typically at 1%-10% levels. The C 10 -C 14  monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunct surfactants such as the amine oxides, betaines and sultaines noted above is also advantageous. If desired, water-soluble magnesium and/or calcium salts such as MgCl 2 , MgSO 4 , CaCl 2 , CaSO 4  and the like, can be added at levels of, typically, 0.1%-2%, to provide additional suds and to enhance grease removal performance. 
     Suds Suppressors 
     Compounds for reducing or suppressing the formation of suds can be incorporated into the compositions of the present invention. Suds suppression can be of particular importance in the so-called “high concentration cleaning process” as described in U.S. Pat. Nos. 4,489,455 and 4,489,574, and in front-loading-style washing machines. 
     A wide variety of materials may be used as suds suppressors, and suds suppressors are well known to those skilled in the art. See, for example, Kirk Othmer Encyclopedia of Chemical Technology, Third Edition, Volume 7, pages 430-447 (John Wiley &amp; Sons, Inc., 1979). Examples of suds supressors include monocarboxylic fatty acid and soluble salts therein, high molecular weight hydrocarbons such as paraffin, fatty acid esters (e.g., fatty acid triglycerides), fatty acid esters of monovalent alcohols, aliphatic C 18 -C 40  ketones (e.g., stearone), N-alkylated amino triazines, waxy hydrocarbons preferably having a melting point below about 100° C., silicone suds suppressors, and secondary alcohols. Suds supressors are described in U.S. Pat. Nos. 2,954,347; 4,265,779; 4,265,779; 3,455,839; 3,933,672; 4,652,392; 4,978,471; 4,983,316; 5,288,431; 4,639,489; 4,749,740; and 4,798,679; 4,075,118; European Patent Application No. 89307851.9; EP 150,872; and DOS 2,124,526. 
     For any detergent compositions to be used in automatic laundry washing machines, suds should not form to the extent that they overflow the washing machine. Suds suppressors, when utilized, are preferably present in a “suds suppressing amount. By “suds suppressing amount” is meant that the formulator of the composition can select an amount of this suds controlling agent that will sufficiently control the suds to result in a low-sudsing laundry detergent for use in automatic laundry washing machines. 
     The compositions herein will generally comprise from 0% to about 10% of suds suppressor. When utilized as suds suppressors, monocarboxylic fatty acids, and salts therein, will be present typically in amounts up to about 5%, by weight, of the detergent composition. Preferably, from about 0.5% to about 3% of fatty monocarboxylate suds suppressor is utilized. Silicone suds suppressors are typically utilized in amounts up to about 2.0%, by weight, of the detergent composition, although higher amounts may be used. Monostearyl phosphate suds suppressors are generally utilized in amounts ranging from about 0.1% to about 2%, by weight, of the composition. Hydrocarbon suds suppressors are typically utilized in amounts ranging from about 0.01% to about 5.0%, although higher levels can be used. The alcohol suds suppressors are typically used at 0.2%-3% by weight of the finished compositions. 
     Water-Soluble Film—The compositions of the present invention may also be encapsulated within a water-soluble film. Preferred film materials are preferably polymeric materials. The film material can, for example, be obtained by casting, blow-moulding, extrusion or blown extrusion of the polymeric material, as known in the art. 
     Preferred polymers, copolymers or derivatives thereof suitable for use as pouch material are selected from polyvinyl alcohols, polyvinyl pyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose, cellulose ethers, cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts, polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthum and carragum. More preferred polymers are selected from polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, and most preferably selected from polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC), and combinations thereof. Preferably, the level of polymer in the pouch material, for example a PVA polymer, is at least 60%. The polymer can have any weight average molecular weight, preferably from about 1000 to 1,000,000, more preferably from about 10,000 to 300,000 yet more preferably from about 20,000 to 150,000. Mixtures of polymers can also be used as the pouch material.
 
Naturally, different film material and/or films of different thickness may be employed in making the compartments of the present invention. A benefit in selecting different films is that the resulting compartments may exhibit different solubility or release characteristics.
 
     Most preferred film materials are PVA films known under the MonoSol trade reference M8630, M8900, H8779 (as described in the Applicants co-pending applications ref 44528 and 11599) and those described in U.S. Pat. No. 6,166,117 and U.S. Pat. No. 6,787,512 and PVA films of corresponding solubility and deformability characteristics. 
     The film material herein can also comprise one or more additive ingredients. For example, it can be beneficial to add plasticisers, for example glycerol, ethylene glycol, diethyleneglycol, propylene glycol, sorbitol and mixtures thereof. Other additives include functional detergent additives to be delivered to the wash water, for example organic polymeric dispersants, etc. 
     Processes of Making the Compositions 
     The compositions of the present invention can be formulated into any suitable form and prepared by any process chosen by the formulator, non-limiting examples of which are described in Applicants&#39; examples and in U.S. Pat.

     Method of Use 
     The present invention includes a method for cleaning and/or treating a textile or hard surface or other surface in fabric or home care. In a preferred aspect of the invention, the method comprises the step of contacting the surface to be treated in a pre-treatment step or main wash step of a washing process, most preferably for use in a textile washing step. In one embodiment of the invention the lipase variant and bleach components are added sequentially into the method for cleaning and/or treating the surface. For example, in a preferred method there may be bleach pre-treatment step in which the bleach component may be contacted with the surface in a pre-treatment step, and the pre-treated surface in the presence of bleach component is then contacted in a second step with the lipase variant. Alternatively the lipase variant may be contacted with the surface prior to later addition of the bleach component. 
     As used herein, washing includes but is not limited to, scrubbing, and mechanical agitation. Drying of such surfaces or fabrics may be accomplished by any one of the common means employed either in domestic or industrial settings. The cleaning compositions of the present invention are ideally suited for use in laundry applications. Accordingly, the present invention includes a method for laundering a fabric. The method comprises the steps of contacting a fabric to be laundered with a said cleaning laundry solution comprising at least one embodiment of Applicants&#39; cleaning composition, cleaning additive or mixture thereof. The fabric may comprise most any fabric capable of being laundered in normal consumer or institutional use conditions. The solution preferably has a pH of from about 8 to about 10.5.

The water to fabric ratio is typically from about 1:1 to about 30:1. 
     The present invention is further described by the following examples that should not be construed as limiting the scope of the invention. 
     EXAMPLES 
     Example 1 
     Automatic Mechanical Stress Assay for Laundry 
     In order to assess the stability to oxidative degradation of the lipase variant, the value for Relative Performance (RPwash) is determined: wash performance (P) of the invention lipase variant against the lipase of SEQ ID NO:1 or RP=P(invention lipase variant)/P(SEQ ID NO:1 lipase). Wash performance is determined by carrying out laundry, washing experiments using the Automatic Mechanical Stress Assay (AMSA). With the AMSA, the wash performance of a large quantity of small volume lipase-detergent solutions can be examined. The AMSA plate has a number of slots for test solutions and a lid firmly squeezing the stained textile against all the slot openings. During the washing time, the plate, test solutions, textile and lid are vigorously shaken to bring the test solution in contact with the textile and apply mechanical stress in a regular, periodic oscillating manner. For further description see WO02/42740 especially the paragraph “Special method embodiments” at page 23-24. 
     The laundry experiments are conducted under the experimental conditions specified below:

     Water hardness is adjusted to 18° dH by addition of CaCl 2 , MgCl 2 , and NaHCO 3  (Ca 2+ :Mg 2+ =4:1:7.5) to the test system. After washing the textiles are flushed in tap water and dried for 5 minutes at 85° C. in a heating cabinet. 
     The wash performance is measured as the brightness of the color of the textile washed. Brightness can also be expressed as the intensity of the light reflected from the sample when illuminated with white light. When the sample is stained the intensity of the reflected light is lower, than that of a clean sample. Therefore the intensity of the reflected light can be used to measure wash performance. 
     Color measurements are made with a professional flatbed scanner (Kodak iQsmart, Kodak, Midtager 29, DK-2605 Brøndby, Denmark), which is used to capture an image of the washed textile. 
     To extract a value for the light intensity from the scanned images, 24-bit pixel values from the image are converted into values for red, green and blue (RGB). The intensity value (Int) is calculated by adding the RGB values together as vectors and then taking the length of the resulting vector:
 
Int=√{square root over ( r   2   +g   2   +b   2 )}.
 
     The wash performance (P) of the lipase variant is calculated in accordance with the following formula: P=ΔInt=Int(v)−Int(r), where Int(v) is the light intensity value of textile surface washed with the lipase variant, and Int(r) is the light intensity value of textile surface washed without the lipase variant. 
     Calculation of Relative Performance score (RPwash): A relative performance score is given as the result of the full scale was washed in accordance with the definition: Relative Performance scores (RPwash) give performance (P) of the invention lipase variant against the conventional lipase: RP═P(invention lipase variant)/P(conventional lipase). A lipase formulation is considered to exhibit improved wash performance, if it performs better than the conventional lipase.
