Enzymes are biodegradable and can be catalytically active already at lower temperatures, which results in reduction of energy consumption. In particular, in the detergent industry enzymes are implemented in washing formulations to improve cleaning efficiency and reducing energy consumption in a washing step.
Amylases are enzymes capable of hydrolyzing starch. Thus, amylases have been employed in the removal of starch stains and have been added to detergent compositions for this purpose. In detergent applications the amylases shall be stable at elevated temperatures and/or within the denaturing conditions of the detergents and the wash liquor. Thus, the need exists for new amylase enzymes, which meet these requirements.

As used in this specification and in the appended claims, the singular forms of "a" and "an" also include the respective plurals unless the context clearly dictates otherwise.
In the context of the present invention, the terms "about" and "approximately" denote an interval of accuracy that a person skilled in the art will understand to still ensure the technical effect of the feature in question. The term typically indicates a deviation from the indicated numerical value of ±20 %, preferably ±15 %, more preferably ±10 %, and even more preferably ±5 %. Furthermore, the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)" etc. and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein. In case the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)", "i", "ii" etc. relate to steps of a method or use or assay there is no time or time interval coherence between the steps, i.e. the steps may be carried out simultaneously or there may be time intervals of seconds, minutes, hours, days, weeks, months or even years between such steps, unless otherwise indicated in the application as set forth herein above or below.
Throughout this application, various publications are referenced. The disclosures of all of these publications and those references cited within those publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this invention pertains.
It is to be understood that the term "comprising" is not limiting. For the purposes of the present invention the term "consisting of" is considered to be a preferred embodiment of the term "comprising". If hereinafter a group is defined to comprise at least a certain number of members, this is meant to also encompass a group which consists of these members only.
“Variant” enzymes differ from “parent” enzymes by certain amino acid alternations, preferably amino acid substitutions at one or more amino acid positions.
In describing the variants of the present invention, the abbreviations for single amino acids are used according to the accepted IUPAC single letter or three letter amino acid abbreviation. “Amino acid alteration” as used herein refers to amino acid substitution, deletion, or insertion. “Substitutions” are described by providing the original amino acid followed by the number of the position within the amino acid sequence, followed by the amino acid, which substitutes the original amino acid. For example, the substitution of histidine at position 120 with alanine is desig- nated as “His120Ala” or “H120A”. Substitutions can also be described by merely naming the resulting amino acid in the variant without specifying the amino acid of the parent at this position, e.g., “X120A” or “120A” or “Xaa120Ala” or “120Ala”.
“Deletions” are described by providing the original amino acid followed by the number of the position within the amino acid sequence, followed by *. Accordingly, the deletion of glycine at position 150 is designated as “Gly150*” or G150*”. Alternatively, deletions are indicated by, e.g., “deletion of D183 and G184”.
“Insertions” are described by providing the original amino acid followed by the number of the position within the amino acid sequence, followed by the original amino acid and the additional amino acid. For example, an insertion at position 180 of lysine next to glycine is designated as “Gly180GlyLys” or “G180GK”. When more than one amino acid residue is inserted, such as, e.g., a Lys and an Ala after Gly180 this may be indicated as “Gly180GlyLysAla” or “G195GKA”. In cases where a substitution and an insertion occur at the same position, this may be indicated as “S99SD+S99A” or in short “S99AD”. Variants comprising multiple alterations are separated by “+”, e.g., “Arg170Tyr+Gly195Glu”, “R170Y+G195E” or “X170Y+X195E” representing a substitution of arginine and glycine at positions 170 and 195 with tyrosine and glutamic acid, respectively. Alternatively, multiple alterations may be separated by space or a comma, e.g., “R170Y G195E” or “R170Y, G195E” respectively. Where different alternative alterations can be introduced at a position, the different alterations are separated by a comma, e.g., “Arg170Tyr, Glu” and “R170T, E”, respectively, represents a substitution of arginine at position 170 with tyrosine or glutamic acid. Alternative substitutions at a particular position can also be indicated as “X120A,G,H”, “120A.G.H”, “X120A/G/H”, or “120A/G/H”. Alternatively, different alterations or optional substitutions may be indicated in brackets, e.g., “Arg170[Tyr, Gly]” or “Arg170{Tyr, Gly}” or in short “R170 [Y, GJ” or “R170 {Y, G}”.
The term “native” (or naturally or wildtype or endogenous) cell or organism or polynucleotide or polypeptide refers to the cell or organism or polynucleotide or polypeptide as found in nature (i.e. , without there being any human intervention).
The term "heterologous” (or exogenous or foreign or recombinant or non-native or non-naturally) polypeptide is defined herein as a polypeptide that is not native to the host cell, a polypeptide native to the host cell in which structural modifications, e.g., deletions, substitutions, and/or insertions, have been made by recombinant DNA techniques to alter the native polypeptide, or a polypeptide native to the host cell whose expression is quantitatively altered or whose expression is directed from a genomic location different from the native host cell as a result of manipulation of the DNA of the host cell by recombinant DNA techniques, e.g., a stronger promoter. Similarly, the term “heterologous” (or exogenous or foreign or recombinant or non-native or non- naturally) polynucleotide refers to a polynucleotide that is not native to the host cell, a polynucleotide native to the host cell in which structural modifications, e.g., deletions, substitutions, and/or insertions, have been made by recombinant DNA techniques to alter the native polynucleotide, or a polynucleotide native to the host cell whose expression is quantitatively altered as a result of manipulation of the regulatory elements of the polynucleotide by recombinant DNA techniques, e.g., a stronger promoter, or a polynucleotide native to the host cell, but integrated not within its natural genetic environment as a result of genetic manipulation by recombinant DNA techniques. With respect to the relation between two or more polynucleotide sequences or the relation between two or more amino acid sequences, the term "heterologous” is used to characterize that the two or more polynucleotide sequences or two or more amino acid sequences are naturally not occurring in the specific combination with each other.
For the purpose of the invention, "recombinant" (or transgenic) with regards to a cell or an organism means that the cell or organism contains a heterologous polynucleotide, which is introduced by man using gene technology. With regards to a polynucleotide “recombinant” includes all constructs produced by using gene technology I recombinant DNA techniques in which either
(a) the sequence of the polynucleotide or a part thereof, or
(b) one or more genetic control sequences, which are operably linked to the polynucleotide, including but not limited to a promoter, or
(c) both a) and b) are not located in their wildtype genetic environment or have been modified by man. A "synthetic" compound is obtained by in vitro chemical and/or enzymatic synthesis.
Variant polynucleotide and variant polypeptide sequences may be defined by their sequence identity when compared to another sequence. Sequence identity usually is provided as “% sequence identity” or “% identity”. For calculation of sequence identities, in a first step a sequence alignment is produced. According to this invention, a pairwise global alignment is produced, meaning that two sequences are aligned over their complete length, which is usually produced by using a mathematical approach, called alignment algorithm.
According to the invention, the alignment is generated by using the algorithm of Needleman and Wunsch (J. Mol. Biol. (1979) 48, p. 443-453). Preferably, the program “NEEDLE” (The European Molecular Biology Open Software Suite (EMBOSS)) is used for the purposes of the current invention, with using the programs default parameter (polynucleotides: gap open=10.0, gap extend=0.5 and matrix=EDNAFULL; polypeptides: gap open=10.0, gap extend=0.5 and ma- trix=EBLOSUM62). After aligning two sequences, in a second step, an identity value is determined from the alignment produced. For this purpose, the %-identity is calculated by dividing the number of identical residues by the length of the alignment region which is showing the respective sequence of the present invention over its complete length multiplied with 100: %-identity = (identical residues I length of the alignment region which is showing the respective sequence of the present invention over its complete length) *100.
For calculating the percent identity of two nucleic acid sequences the same applies as for the calculation of percent identity of two amino acid sequences with some specifications. For nucleic acid sequences encoding for a protein the pairwise alignment shall be made over the complete length of the coding region of the sequence of this invention from start to stop codon excluding introns. Introns present in the other sequence, to which the sequence of this invention is compared, shall also be removed for the pairwise alignment. After aligning two sequences, in a second step, an identity value is determined from the alignment produced. Percent identity is calculated by %-identity = (identical residues I length of the alignment region which is showing the sequence of the invention from start to stop codon excluding introns over its complete length) *100.
Moreover, the preferred alignment program for nucleic acid sequences implementing the Needleman and Wunsch algorithm (J. Mol. Biol. (1979) 48, p. 443-453) is “NEEDLE” (The European Molecular Biology Open Software Suite (EMBOSS)) with the programs default parameters (gapopen=10.0, gapextend=0.5 and matrix=EDNAFULL).
Variant polypeptides may also be defined by their sequence similarity when compared to another sequence. Sequence similarity usually is provided as “% sequence similarity” or “%-similarity”. % sequence similarity takes into account that defined sets of amino acids share similar properties, e.g. by their size, by their hydrophobicity, by their charge, or by other characteristics. Herein, the exchange of one amino acid with a similar amino acid may be called “conservative mutation”. Similar amino acids according to the invention are defined as follows, which shall also apply for determination of %-similarity according to this invention, which is also in accordance with the BLOSUM62 matrix as for example used by program “NEEDLE”, which is one of the most used amino acids similarity matrix for database searching and sequence alignments:
Amino acid A is similar to amino acids S
Amino acid D is similar to amino acids E; N
Amino acid E is similar to amino acids D; K; Q Amino acid F is similar to amino acids W; Y Amino acid H is similar to amino acids N; Y Amino acid I is similar to amino acids L; M; V
Amino acid K is similar to amino acids E; Q; R
Amino acid L is similar to amino acids I; M; V Amino acid M is similar to amino acids I; L; V Amino acid N is similar to amino acids D; H; S Amino acid Q is similar to amino acids E; K; R Amino acid R is similar to amino acids K; Q Amino acid S is similar to amino acids A; N; T Amino acid T is similar to amino acids S Amino acid V is similar to amino acids I; L; M Amino acid W is similar to amino acids F; Y Amino acid Y is similar to amino acids F; H; W For calculation of sequence similarity, in a first step a sequence alignment is produced as described above. After aligning two sequences, in a second step, a similarity value is determined from the alignment produced. For this purpose, the %-similarity is calculated by dividing the number of identical residues plus the number of similar residues by the length of the alignment region which is showing the sequence of the invention over its complete length multiplied with 100: Cosimilarity = [(identical residues + similar residues) I length of the alignment region which is showing the sequence of the invention over its complete length] *100.
For nucleic acids, similar sequences can also be determined by hybridization using respective stringency conditions. The term "high stringency conditions" means for probes of at least 100 nucleotides in length, prehybridization and hybridization at 42°C in 5X SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, following standard Southern blotting procedures for 12 to 24 hours. The carrier material is finally washed three times each for 15 minutes using 2X SSC, 0.2% SDS at 65°C. The term "very high stringency conditions" means for probes of at least 100 nucleotides in length, prehybridization and hybridization at 42°C in 5X SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, following standard Southern blotting procedures for 12 to 24 hours. The carrier material is finally washed three times each for 15 minutes using 2X SSC, 0.2% SDS at 70°C.
A "fragment" or “subsequence” as used herein are a portion of a polynucleotide or an amino acid sequence. The term “functional fragment” refers to any nucleic acid or amino acid sequence which comprises merely a part of the full-length amino acid sequence, respectively, but still has the same or similar activity and/or function. Preferably, the functional fragment is at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80% identical, at least 81 %, at least
82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least
89%, 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 98.5 %, at least 99%, or at least 99.5% identical to the original full length amino acid sequence. The functional fragment comprises consecutive nucleotides or amino acids compared to the original nucleic acid or original amino acid sequence, respectively.
“Genetic construct” or “expression cassette” as used herein, is a nucleic acid molecule composed of at least one sequence of interest to be expressed, operably linked to one or more control sequences (at least to a promoter) as described herein.
The term “vector” as used herein comprises any kind of construct suitable to carry foreign polynucleotide sequences for transfer to another cell, or for stable or transient expression within a given cell. The term “vector” as used herein encompasses any kind of cloning vehicles, such as but not limited to plasmids, phagemids, viral vectors (e.g., phages), bacteriophage, baculoviruses, cosmids, fosmids, artificial chromosomes, and any other vectors specific for specific hosts of interest. Foreign polynucleotide sequences usually comprise a coding sequence which may be referred to herein as “gene of interest”. The gene of interest may comprise introns and exons, depending on the kind of origin or destination of host cell.
The term “introduction of a polynucleotide” or “transformation of a polynucleotide” as referred to herein encompasses the transfer of an exogenous polynucleotide into a host cell, irrespective of the method used for transfer. That is, the term “transformation of a polynucleotide” as used herein is independent from vector, shuttle system, or host cell, and it not only relates to the polynucleotide transfer method of transformation as known in the art (cf., for example, Sambrook, J. et al. (1989) Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY), but it encompasses any further kind polynucleotide transfer methods such as, but not limited to, transduction or transfection.
A polynucleotide encoding a polypeptide may be “expressed”. The term “expression” or “gene expression” means the transcription of a gene or genes or genetic construct into structural RNA (e.g., rRNA, tRNA) or mRNA with or without subsequent translation of the latter into a protein. The process includes transcription of DNA and processing of the resulting mRNA product.
The term “purification” or “purifying” refers to a process in which at least one component, e.g., a protein of interest, is separated from at least another component, e.g., a particulate matter of a fermentation broth, and transferred into a different compartment or phase, wherein the different compartments or phases do not necessarily need to be separated by a physical barrier. Examples of such different compartments are two compartments separated by a filtration membrane or cloth, i.e. , filtrate and retentate; examples of such different phases are pellet and supernatant or cake and filtrate, respectively. The resulting solution after purifying the enzyme of interest from the fermentation broth is called herein “purified enzyme solution”.
“Protein formulation” (or “enzyme preparation”), e.g., “protein variant formulation”, means any non-complex formulation comprising a small number of ingredients, wherein the ingredients serve the purpose of stabilizing the proteins comprised in the protein formulation and/or the stabilization of the protein formulation itself. Preferably, the non-complex protein formulation comprises the protein in higher concentrations than the complex formulation, e.g., than a detergent composition. Thus, preferably the non-complex protein formulation is a concentrated protein variant formulation. Preferably, non-complex protein formulations comprise 2 to 120 mg/g active enzyme, wherein complex formulations, like detergent compositions, comprise 0.002 to 6 mg/g active enzyme.
“Enzyme properties” include, but are not limited to catalytic activity, substrate/cofactor specificity, product specificity, stability in the course of time, thermostability, pH stability, and chemical stability. “Enzymatic activity” or “catalytic activity” means the catalytic effect exerted by an enzyme, expressed as units per milligram of enzyme (specific activity) or molecules of substrate transformed per minute per molecule of enzyme (molecular activity). Enzymatic activity can be specified by the enzymes actual function, e.g., proteases exerting proteolytic activity by catalyzing hydrolytic cleavage of peptide bonds, lipases exerting lipolytic activity by hydrolytic cleavage of ester bonds, amylases activity involves hydrolysis of glycosidic linkages in polysaccharides, etc.
The term “enzyme stability” according to the current invention relates to the retention of enzymatic activity as a function of time during storage or operation. Retention of enzymatic activity as a function of time during storage is called “storage stability” and is preferred within the context of the invention.
To determine and quantify changes in catalytic activity of enzymes stored or used under certain conditions over time, the “initial enzymatic activity” is measured under defined conditions at time zero (100%) and at a certain point in time later (x%). By comparison of the values measured, a potential loss of enzymatic activity can be determined in its extent. The extent of enzymatic activity loss determines an enzyme’s stability or non-stability.
“Enzyme inhibitors” as used herein are compounds that slow down or halt enzymatic activity. Enzyme inhibitors frequently also stabilize the enzyme in its three-dimensional structure. Hence, enzyme inhibitors usually also act as “enzyme stabilizers”. “pH stability” refers to the ability of an enzyme to exert enzymatic activity after exposure to certain pH value.
The terms “thermal stability”, “thermostability” or “temperature-dependent activity” refer to the ability of an enzyme to exert catalytic activity or wash performance after exposure to elevated temperatures, preferably, at a temperature of 40 °C for 28 days, preferably 56 days, preferably in a detergent composition (preferably, in model ES1-C detergent), or at 92 °C for at least 10min. The terms “detergent stability” or “stability under storage in a detergent composition” refer to the ability of an enzyme to exert catalytic activity or wash performance after storage in a detergent composition, preferably, at a temperature of 40 °C or 50 °C for 28 days, preferably 56 days, in a detergent composition (preferably, in model ES1-C detergent).
“Improvement Factor” (IF) is the degree of improvement of an enzyme variant in a certain property, preferably over the respective parent enzyme. An improvement of the enzyme variant, preferably over the respective parent enzyme, is characterized by an Improvement Factor (IF) of >1 .0. The improvement factor can alternatively be expressed in percentages, e.g., and IF of 1.1 equals 110%.
As used herein, "wash performance" (also called herein “cleaning performance”) of an enzyme refers to the contribution of the enzyme to the cleaning performance of a detergent composition, i.e. the cleaning performance added to the detergent composition by the performance of the enzyme. The term “wash performance” is used herein similarly for laundry and hard surface cleaning. Wash performance is compared under relevant washing conditions. The term "relevant washing conditions" is used herein to indicate the conditions, particularly washing temperature, time, washing mechanics, sud concentration, type of detergent and water hardness, actually used in households in a detergent market segment. The term "improved wash performance" is used to indicate that a better end result is obtained in stain removal under relevant washing conditions, or that less enzyme, on weight basis, is needed to obtain the same end result relative to the corresponding control conditions.
As used herein, the term "specific performance" refers to the cleaning and removal of specific stains or soils per unit of active enzyme. In some embodiments, the specific performance is determined using stains or soils such as egg, egg yolk, milk, grass, minced meat blood, chocolate sauce, baby food, sebum, etc.
“Detergent composition”, “detergent formulation”, or “detergent” means compositions designated for cleaning soiled material. Detergent compositions according to the invention include detergent compositions for different applications such as laundry and hard surface cleaning. The term “detergent component” is defined herein to mean a type of chemical, which can be used in detergent compositions. A typical detergent component is a surfactant. "Surfactant" (synonymously used herein with “surface active agent”) means an organic chemical that, when added to a liquid, changes the properties of that liquid at an interface. According to its ionic charge, a surfactant is called non-ionic, anionic, cationic, or amphoteric. The term “effective amount of a detergent component” includes amounts of certain components to provide effective stain removal and/or effective cleaning conditions (e.g. pH, temperature, water hardness), amounts of certain components to effectively provide optical benefits (e.g. optical brightening, dye transfer inhibition, color care), and amounts of certain components to effectively aid the processing (maintain physical characteristics during processing, storage and use; e.g. rheology modifiers, hydrotropes, desiccants). The term “laundry” or “laundering” relates to both household laundering and industrial laundering and means the process of treating textiles and/or fabrics with a solution containing a detergent composition of the present invention. The laundering process may be carried out by using technical devices such as a household or an industrial washing machine. Alternatively, the laundering process may be done by hand.
The term “textile” means any textile material including yarns (thread made of natural or synthetic fibers used for knitting or weaving), yarn intermediates, fibers, non-woven materials, natural materials, synthetic materials, as well as fabrics made of these materials such as garments, cloths and other articles. The terms “fabric” (a textile made by weaving, knitting or felting fibers) or “garment” (any article of clothing made of textile) as used herein, mean to include the broader term textile as well.
The term “fibers” includes natural fibers, synthetic fibers, and mixtures thereof. Examples of natural fibers are of plant (such as flax, jute and cotton) or animal origin, comprising proteins like collagen, keratin and fibroin (e.g. silk, sheep wool, angora, mohair, cashmere). Examples for fibers of synthetic origin are polyurethane fibers such as Spandex® or Lycra®, polyester fibers, polyolefins such as elastofin, or polyamide fibers such as nylon. Fibers may be single fibers or parts of textiles such as knitwear, woven or non-woven fabrics.
The term “hard surface cleaning” relates to both household hard surface cleaning and industrial hard surface cleaning and means the process of treating hard surfaces with a solution containing a detergent composition of the present invention. Hard surfaces may include any hard surfaces in the household or industry, such as floors, furnishing, walls, sanitary ceramics, glass, metallic surfaces including medical devices, cutlery, and dishes. A particular form of hard surface cleaning is dishwashing, manual dish washing (MDW) or automatic dishwashing (ADW). The term “dish wash” refers to all forms of washing dishes, e.g. by hand or automatic dish wash. Washing dishes includes, but is not limited to, the cleaning of all forms of crockery such as plates, cups, glasses, bowls, all forms of cutlery such as spoons, knives, forks and serving utensils as well as ceramics, plastics such as melamine, metals, china, glass and acrylics.
Cleaning performance is evaluated under relevant cleaning conditions. The term "relevant cleaning conditions" herein refers to the conditions, particularly cleaning temperature, time, cleaning mechanics, suds concentration, type of detergent and water hardness, actually used in laundry machines, automatic dish washers or in manual cleaning processes.
The term “medical device cleaning” refers to the cleaning step in reprocessing reusable medical devices. Medical device cleaning methods can be divided into two categories, manual and me- chanical/automated cleaning methods. Manual cleaning is used when mechanical units are not available or medical devices to be cleaned are too fragile or difficult to clean with a mechanical unit. Mechanical/automated cleaning methods remove soiling and microorganisms through an automated cleaning and rinsing process, this includes ultrasonic cleaning and washing.
In the field of detergency, usually the term “stains” is used with reference to laundry, e.g., cleaning for textiles, fabric, or fibers, whereas the term “soils” is usually used with reference to hard surface cleaning, e.g., cleaning of dishes and cutlery. However, herein the terms “stain” and “soil” shall be used interchangeably.
A “sequestering builder” as used herein is different from a precipitating builder in that no significant amount of precipitate is formed when the builder is used in an amount sufficient to combine with all of the calcium ions in an aqueous solution with 7 °dH hardness (German hardness) initially at neutral pH. A “strong builder” is classified as high efficiency chelators that can bind the divalent cations such as Ca2+ strongly with a logarithmic stability constant (Log KCa ) of the cat- ion/chelator complex of above 4, particular above 5, above 6 or above 7. The stability constants are determined at an ionic strength of 0.1 M and at a temperature of 25°C. A ..strong sequestering builder” combines both of the above-mentioned properties.
The term “low temperature” as used herein refers to a temperature range equal or below 40 °C, preferably 10-40 °C, more preferably 20-40 °C, more preferably 20-35 °C.
Detailed description
In the present invention new amylase enzymes are provided. More specifically, amylase variants, methods of making the amylase variants, compositions comprising the amylase variants, and methods of using the amylase variants or compositions comprising the amylase variants are provided. Amylase variant
The present invention is directed to an amylase variant of a parent amylase, wherein said variant comprises
(i) an amino acid substitution at position 25 according to the numbering of SEQ ID NO: 3,
(ii) an amino acid substitution at one or more, preferably two or more, amino acid positions corresponding to amino acid positions selected from the group consisting of 116, 176, 181 , 186, 195, 206, 225, 320, and 482 according to the numbering of SEQ ID NO: 3, and
(iii) at least 60%, preferably at least 91 % identity, but less than 100% sequence identity with SEQ ID NO: 1 , 3, 4, or in any of SEQ ID NO: 15-41 , preferably of SEQ ID NO: 1 or SEQ ID NO: 3, preferably SEQ ID NO: 1 , preferably wherein the parent amylase of the amylase variant is an amylase according to SEQ ID NO: 1 or SEQ ID NO: 3, preferably SEQ ID NO: 1.
The amylase variant of the present invention is a non-naturally occurring amylase. Preferably, the amylase variant is an alpha-amylase. Preferably, the amylase variant of the present invention is a purified, isolated, synthetic, and/or recombinant amylase variant. Preferably, the amylase variant of the present invention is a purified and recombinant amylase variant.
Amylases and amylase variants according to the invention have “amylolytic activity” or “amylase activity”. “Amylolytic activity” or “amylase activity” describes the capability for the hydrolysis of glucosidic linkages in polysaccharides. Amylase activity may be determined by assays for measurement of amylase activity which are known to those skilled in the art. Examples for assays measuring amylase activity are the Phadebas assay or the EPS assay (“Infinity reagent”). In the Phadebas assay amylase activity is determined by employing Phadebas tablets as substrate (Phadebas Amylase Test, supplied by Magle Life Science). Starch is hydrolyzed by the amylase giving soluble blue fragments. The absorbance of the resulting blue solution, measured spectrophotometrically at 620 nm, is a function of the amylase activity. The measured absorbance is directly proportional to the specific activity (activity/mg of pure amylase protein) of the amylase in question under the given set of conditions.
Alternatively, amylase activity can also be determined by a method employing the Ethyliden-4- nitrophenyl-alpha-D-maltoheptaosid (EPS). D-maltoheptaoside is a blocked oligosaccharide which can be cleaved by an endo-amylase. Following the cleavage, the alpha-glucosidase included in the kit to digest the substrate to liberate a free PNP molecule which has a yellow color and thus can be measured by visible spectophotometry at 405nm. Kits containing EPS substrate and alpha-glucosidase is manufactured for example by Roche Costum Biotech (cat. No. 10880078103). The slope of the time dependent absorption-curve is directly proportional to the specific activity (activity per mg enzyme) of the amylase in question under the given set of conditions.

Nucleic acid construct
The present invention also refers to a polynucleotide encoding the amylase variant of the present invention. Preferably, the polynucleotide is a codon-optimized polynucleotide for improving expression in a specific host cell, preferably a Bacillus cell.
The present invention thus also refers to a nucleic acid, preferably an isolated, a synthetic, and/or a recombinant nucleic acid comprising:
(a) a nucleic acid sequence having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 85.5%, at least 86%, at least 86.5%, at least 87%, at least 87.5%, at least 88%, at least 88.5%, at least 89%, at least 89.5%, at least 90%, at least 90.5%, at least 91 %, at least 91.5%, at least 92%, at least 92.5%, at least 93%, at least 93.5%, at least 94%, at least 94.5%, at least 95%, at least 95.5%, at least 96%, at least 96.5%, at least 97%, at least 97.5%, at least 98%, at least 98.5%, at least 99%, or at least 99.5%, but less than 100% identity to SEQ ID NO: 2, wherein the nucleic acid encodes an amylase variant having amylase activity described herein;
(b) a nucleic acid sequence encoding a polypeptide having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 81 %, at least 82%, at least 83%, at least 84%, at least 85%, at least 85.5%, at least 86%, at least 86.5%, at least 87%, at least 87.5%, at least 88%, at least 88.5%, at least 89%, at least 89.5%, at least 90%, at least 90.5%, at least 91 %, at least 91 .5%, at least 92%, at least 92.5%, at least 93%, at least 93.5%, at least 94%, at least 94.5%, at least 95%, at least 95.5%, at least 96%, at least 96.5%, at least 97%, at least 97.5%, at least 98%, at least 98.5%, at least 99%, or at least 99.5%, but less than 100% identity to SEQ ID NO: 1 , wherein the nucleic acid encodes an amylase variant having amylase activity described herein;
(c) a polynucleotide that hybridizes under high stringency conditions, preferably under very high stringency conditions, with the complement of
(i) a coding sequence of SEQ ID NO: 1 or a coding sequence of any amylase variant having amylase activity described herein; or
(ii) a polynucleotide shown in SEQ ID NO: 2; (d) a fragment of (a), (b), or (c), wherein the fragment encodes a polypeptide having amylase activity; or
(e) a nucleic acid sequence fully complementary to any of (a) to (d).
(f) a polynucleotide that differs from any of the nucleic acid sequences described in (a) to (e) merely by the degeneracy of the genetic code.
The present invention also refers to a nucleic acid construct, preferably an expression cassette, comprising the polynucleotide as described herein.
Typically, the expression cassette comprises three elements: a promoter sequence, an open reading frame, and a 3' untranslated region that, in eukaryotes, usually contains a polyadenylation site. Additional regulatory elements may include transcriptional as well as translational enhancers. An intron sequence may also be added to the 5' untranslated region (UTR) or in the coding sequence to increase the amount of the mature message that accumulates in the cytosol. The expression cassette may be part of a vector or may be integrated into the genome of a host cell and replicated together with the genome of its host cell. The expression cassette usually is capable of increasing or decreasing expression.
The present invention also refers to an expression vector comprising the polynucleotide or the nucleic acid construct as described herein. The expression vector can be a low copy number vector or high copy number vector.
A vector as used herein may provide segments for transcription and translation of a foreign polynucleotide upon transformation into a host cell or host cell organelles. Such additional segments may include regulatory nucleotide sequences, one or more origins of replication that is required for its maintenance and/or replication in a specific cell type, one or more selectable markers, a polyadenylation signal, a suitable site for the insertion of foreign coding sequences such as a multiple cloning site etc. One example is when a vector is required to be maintained in a bacterial cell as an episomal genetic element (e.g., plasmid or cosmid molecule). Non-limiting examples of suitable origins of replication include the f1 -ori and colE1.
A vector may replicate without integrating into the genome of a host cell, e.g., as a plasmid in a bacterial host cell, or it may integrate part or all of its DNA into the genome of the host cell and thus lead to replication and expression of its DNA.
The polynucleotide encoding the amylase variant may be introduced into a vector by means of standard recombinant DNA techniques. Once introduced into the vector, the polynucleotide comprising a coding sequence may be suitable to be introduced (transformed, transduced, transfected, etc.) into a host cell or host cell organelles. A cloning vector may be chosen suitable for expression of the polynucleotide sequence in the host cell or host cell organelles. Host cell
The present invention also refers to a host cell comprising the polynucleotide encoding the amylase variant as described herein, the nucleic acid construct as described herein, or the expression vector as described herein. In one embodiment of the invention, a vector is used for transformation of a host cell.
The polynucleotide encoding the amylase variant as described herein may be transiently or stably introduced into a host cell and may be maintained non-integrated, for example, as a plasmid. Usually, stable transformation is due to integration of nucleic acid comprising a foreign coding sequence into the chromosomes or as an episome (separate piece of nuclear DNA). Usually, transient transformation is due to nucleic acid comprising a foreign nucleic acid sequence is not integrated into the chromosomes or as an episome. Alternatively, the polynucleotide encoding the amylase variant as described herein may be integrated into the host genome.
The introduction of nucleic acid into a host cell may, for instance, but not limited thereto, be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979, Molecular General Genetics 168: 111-115), by using competent cells (see, e.g., Young and Spizizen, 1961 , Journal of Bacteriology 81 : 823-829, or Dubnau and Davidoff-Abelson, 1971 , Journal of Molecular Biology 56: 209-221), by electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742- 751), or by conjugation (see, e.g., Koehler and Thorne, 1987, Journal of Bacteriology 169: 5271-5278). Specific transformation protocols are known in the art for various types of host cells (see, e.g., for E. coli protoplast transformation see Hanahan, 1983, J. Mol. Biol. 166: 557-580). Various host cells can be used for expressing the nucleic acid construct described herein. Host cells comprising the genetic constructs described herein can be obtained by one of the methods described herein for introducing the polynucleotides into such host cells.

A preferred embodiment of the present invention is a method of obtaining an amylase variant of a parent amylase comprising the steps of: a) introducing into a parent amylase, preferably into SEQ ID NO: 1 or SEQ ID NO: 3, preferably SEQ ID NO: 1 ,
(i) an amino acid substitution at position 25 according to the numbering of SEQ ID NO: 3,
(ii) an amino acid substitution at one or more, preferably two or more, amino acid positions corresponding to amino acid positions selected from the group consisting of 116, 176, 181 , 186, 195, 206, 225, 320, and 482 according to the numbering of SEQ ID NO: 3, b) preferably introducing a deletion at two or more positions in the parent amylase selected from positions 181 , 182, 183, and 184 according to the numbering of SEQ ID NO: 3; and thereby providing an amylase variant of said parent amylase, wherein said variant has at least 80%, but less than 100% sequence identity to the amino acid sequence to the polypeptide of SEQ ID NO: 1 , and wherein said amylase variant has amylase activity and preferably wherein the amylase variant has an improved property, preferably relative to said parent.
Ways of introducing amino acid alterations, e.g., a substitution or a deletion, into protein sequence are well known in the art. The variants may be prepared using any mutagenesis procedure known in the art, such as site-directed mutagenesis, synthetic gene construction, semisynthetic gene construction, random mutagenesis, shuffling, etc.
The obtained amylase variant can be produced in an industrial scale and subsequently purified. Industrial production of enzymes usually is done by cultivating a host cell (also called fermentation) which expresses the enzyme. Suitable host cells are described herein. A nucleic acid sequence encoding the amylase variant described herein can be transformed into the host cell, which is subsequently cultivated under conditions suitable for the host cell to produce the amylase variant. In a preferred embodiment, the amylase variant is purified from the host cell.
Hence, in yet another embodiment, the present invention is directed to a method of producing an amylase variant, comprising the steps of
(a) providing a host cell comprising a heterologous nucleic acid construct comprising a polynucleotide encoding the amylase variant described herein by introducing the nucleic acid construct comprising the polynucleotide encoding the amylase variant as described herein into the host cell;
(b) cultivating the recombinant host cell of step (a) under conditions conductive for the expression of the polynucleotide; and
(c) optionally, recovering the amylase variant encoded by the polynucleotide.
Cultivation of the host cell normally takes place in a suitable nutrient medium allowing the recombinant cells to grow and express the desired protein. At the end of fermentation, the fermentation broth is collected and may be further processed, wherein the fermentation broth comprises a liquid fraction and a solid fraction. The enzyme of interest may be further purified from the fermentation broth.
The amylase variant described herein may be secreted (into the liquid fraction of the fermentation broth) or may not be secreted from the microbial cells (and therefore is comprised in the cells of the fermentation broth). Depending on this, the amylase variant may be recovered from the liquid fraction of the fermentation broth or from cell lysates. Preferably, the amylase variant is secreted from the cell into the fermentation broth, preferably by means of a secretion signal peptide added to the terminus of the amino acid sequence of the amylase variant. Recovery of the amylase variant can be achieved by methods known to those skilled in the art. Suitable methods for recovery of proteins from fermentation broth include but are not limited to collection, centrifugation, filtration, extraction, and precipitation. If the product of interest precipitates or crystallizes in the fermentation broth or binds at least in part to the particulate matter of the fermentation broth additional treatment steps might be needed to release the protein of interest from the biomass or to solubilize protein of interest crystals and precipitates. W00043502A1 , W02008110498 A1 , and WO2017097869A1 describe a method for recovering a protein of interest, which precipitates and/or crystallizes during fermentation, from the fermentation broth. In case the desired protein is comprised in the cells of the fermentation broth release of the product of interest from the cells might be needed.

Examples
General methods:
Amylase Expression
Genes coding for the amylases were cloned by restriction-ligation based standard protocols into a gram-positive expression vector comprising a promoter sequence, a sequence coding for a secretion signal peptide, and a ribosome binding site. Post reaction, the plasmid assembly mixtures were transformed into B. subtilis PY79 by established natural-competency transformation methods. Successful transformations were selected by plating on LB agar plates supplemented with 20 pg/ml kanamycin sulfate and incubating overnight at 37 degrees C. After the overnight selection, individual colonies were obtained which were then grown in a rich medium (e.g., LB broth) with 20 pg/ml kanamycin sulfate overnight at 37 degrees with shaking at 250 rpm. The following morning, cells were pelleted by centrifugation, and plasmid DNA was isolated by alkaline lysis method with a Macherey-Nagel NucleoSpin kit. The isolated DNA could then be transformed into electrocom petent Bacillus licheniformis cells.
The B. licheniformis cells were made electrocompetent by standard gram-positive electrocom- petent cell preparation techniques. As an example, the cells were prepared by growing the B. licheniformis strain in an osmolyte-dense rich medium (e.g., LB broth with 0.5 M D-sorbitol) and harvesting the cells in early exponential growth phase. Cells were harvesting by chilling on ice and pelleting by centrifugation. Following the harvest, cells were washed to remove salts with an osmolyte-rich washing buffer (e.g., 10% glycerol with 0.5M D-sorbitol and 0.5M D-mannitol) by 3 cycles of suspension and pelleting by centrifugation. Finally, cells were concentrated by resuspending in the washing buffer at 1 to 10% of the original culture volume.
Once prepared, plasmid DNA was added the B. licheniformis electrocompetent cells in a 0.2 cm Bio-Rad electroporation cuvette. The cells were electroporated with a Bio-Rad Gene Pulser Xcell per manufacturer’s instructions. Cells were immediately rescued after the shock by addition of 1 ml of the osmolyte-dense rich medium. After two hours for of recovering at 37 degrees C, the successful transformants were then selected by plating on LB agar plates supplemented with 20 pg/ml kanamycin sulfate and incubating overnight at 37 degrees C.
Amylase expression and protein quantification
Single colonies of the expression strains were picked into 60 pL of rich medium (e.g. LB broth) supplemented with 20 pg/mL kanamycin sulfate in a 96-well plate (GE Life Sciences part 28403943). The cultures were grown at 37 degrees C for 16 hours, then 15 pL of culture was used to inoculate 600 pL of defined glucose-mineral media and 20 pg/mL kanamycin sulfate in a 96 well plate. The cultures were grown at 37 degrees C for 48 hours, after which the supernatant was harvested by pelleting the cells with centrifugation and removing the residual culture liquid. Larger amounts were created by combing the supernatant of identical clones. The expression levels (concentration in mg/mL) of alpha-amylases activity were identified by LabChip (LC) analysis to allow equal dosing in laundry detergent.
Amylase activity measurements q-amylase activity can be determined by a method employing the Ethyliden-4-nitrophenyl-a-D- maltoheptaosid (EPS) as substrate. D-maltoheptaoside is a blocked oligosaccharide which can be cleaved by an endo-amylase. Following the cleavage, the a-glucosidase included in the kit to digest the substrate to liberate a free PNP molecule which has a yellow color and thus can be measured by visible spectophotometry at 405nm. Kits containing EPS substrate and a-gluco- sidase is manufactured by Roche Costum Biotech (cat. No. 10880078103) or Thermo Scientific (TR25421). The slope of the time dependent absorption-curve is directly proportional to the specific activity (activity per mg enzyme) of the a-amylase in question under the given set of conditions. The residual activity was calculated by dividing the activity after storage time with the activity of the sample at time point zero. The residual activity was compared to the residual activity of the reference given in the example below.
Example 1 : Storage stability in builder-containing detergent at 40 °C for up to 84 days.

Figure imgf000124_0001
(*) Amylase variant of SEQ ID NO: 1 with the mutations given in the numbering of SEQ ID NO: 3.
The amylases were formulated in a liquid model detergent (ES1-C) and tested for their residual activity after 84 days of storage at 40°C. Final dosing was 0.1 g/L of amylase. To assess the stability of the amylases in presence of strong chelators, HEDP and/or CaCh was supplemented as indicated in the table. No additional Ca2+ was supplemented by the enzymes.
Table 3: ES1-C formulation:
Figure imgf000124_0002
After indicated timepoints sample were taken and residual activity was measured using EPS as substrate as indicated above. The residual activity was calculated by dividing the activity after storage time with the activity of the sample at time point zero. The residual activity was compared to the residual activity of a reference amylase (SEQ ID NO: 33).
Table 4:

As can be derived from the table above, an amylase variant of the present invention is more stable than the reference amylase. Example 2: Wash performance of improved amylases
Determination of the wash performance was performed using a Launder-o-meter: Several soiled swatches were washed together with cotton ballast fabric and 20 steel balls at 40 °C in a liquid laundry formulation. After the wash, the fabrics were rinsed, spin-, and air- dried. The washing performance was determined by measuring the Cl ELab values of the soiled fabrics before and after wash using the MACH5 multi area color measurement. For data evaluation, AE was calculated between unwashed and washed stains and AAE was calculated between detergent with enzymes and detergent without enzymes. The data represent average values of two separate experiments.

As can be derived from the table above, an amylase variant of the present invention provides better cleaning result compared to the reference amylase.
Determination of Wash Performance in Full Scale washing machines:
A multi-stain monitor was washed in full scale washing machines in presence with cotton ballast fabric at 40 °C in a liquid laundry formulation with different amylases. Each stain was washed in quadruplicates (2 machines with two pieces per stain per machine). After the wash, the stain monitor was air-dried. The washing performance was determined by measuring the CIELab values of the soiled fabrics before and after wash using the MACH5 multi area color measurement. For data evaluation mean values were determined, AY was calculated between unwashed and washed stains and AAY was calculated between detergent with enzymes and detergent without enzymes.
