Detergent compositions comprising a mannanase and a clay}
Field of invention
The present invention relates to laundry detergents and / or textile care compositions comprising mannanases and clays.
Background of the Invention
The performance of detergent products is determined by a variety of factors including decontamination ability, prevention of re-deposition of contamination, or contaminant products on the product during cleaning. Thus, detergent compositions currently comprise complex combinations of active ingredients that meet certain specific needs. In particular, recent detergent formulations generally include detergent and detergent enzymes that provide cleaning and fabric protection benefits. In addition, there is a need in the art for detergent compositions that exhibit not only good detergency but also fabric softening performance and other fabric protection benefits.
Softened clays are commonly used in recent laundry detergents and fabric protection compositions to provide a soft feel. EP-A 177 165 describes the use of softened clays with cellulase in detergent compositions. EP-A 495 258 describes detergent compositions comprising surfactants, extender systems, softening clays and cellulase.
Food and cosmetic stains / contaminations represent the majority of consumer-related stains / contaminations and often include food additives such as thickeners / stabilizers. Indeed, hydrocollide gums and emulsifiers are commonly used food additives. The term "gum" refers to a group of industrially useful polysaccharides (long chain polymers) or derivatives thereof that hydrate in hot or cold water to form viscous solutions, dispersions or gels. Black is classified into natural and modified. Natural black seaweed extract, plant extrudates, gums from seeds or roots and gums obtained by microbial fermentation. Modified (semisynthetic) gums include cellulose and starch derivatives and certain synthetic gums such as lower methoxyl pectin, propylene glycol alginate, and carboxymethyl and hydropropyl guar gum.

Baird, Kelco division of Merck.
Guar gum legumes used in these food and cosmetic stains are obtained from seed endosperm of Cyamopsis tetragonoloba. Guar gum (also called guaran) extracted from dicotyledonous seeds consists of 1-4, bD-mannopyranosyl unit backbones and is used as a thickening agent in dressing and frozen products and cosmetics [ Reference: H.-D.

Locus bean gum (also called carob bean gum or St Jon's bread) is also extracted from the seeds of evergreen trees used in the food industry and grown in the Mediterrannean region. Locus bean gum has a 1-4, b-D-mannopyranosyl backbone that is probably different from the structure of guar gum in that there are fewer D-galactosyl side chains. In legume seeds, water-soluble calactomannan is in some cases the main storage carbohydrate, accounting for less than 20% of the total dry weight. Galactomannans have α-galactose bound to O-6 of mannose residues and can also be acetylated to varying degrees for O-2 and O-3 of mannose residues.
However, clays do not blend with some hydrocolloid gums contained in these food and cosmetic stains. In the art, guar gums are recognized to induce precipitation of clay due to the potential for flocculation of clay or clay particles. Industrial Gum, second editions, R.L. Whistler pp 307, Academic Press, 1973, ISBN, 0-12-74-6252-x.
It is therefore an object of the present invention to provide laundry detergents and / or fabric protection compositions which exhibit optimal softening performance and in particular provide optimum stain removal and cleaning performance for cosmetic and food stains.
This object is achieved by preparing laundry detergents and / or fabric protection compositions comprising metnanase enzyme and clay as emollients.
It has further been found that the performance of the detergent compositions of the present invention is enhanced by adding laundry detergents and / or fabric protective ingredients selected from extenders, cellulase and / or cationic surfactants.

However, synthetic formulations of mannanases and clays for optimal softening performance in laundry detergents and / or fabric protection compositions and in particular for optimal stain removal and cleaning performance for cosmetic and food stains have never been recognized.
Summary of the Invention
The present invention relates to laundry detergents and / or fabric protection compositions comprising metnase and clay to provide optimum softening performance and in particular to optimal stain removal and cleaning performance for cosmetic and food stains.
Detailed description of the invention
In the art, clay is known to be incompatible with some hydrocolloid gums contained in, for example, food and cosmetic stains. Guar gum has been recognized to induce precipitation of clay due to its potential for flocculation of clay or clay particles [Industrial Gum, second editions, R.L. Whistler pp 307, Academic Press, 1973, ISBN, 0-12-74-6252-x.
Without wishing to be bound by theory, these aggregated clays have been found to reduce the softening effect. In addition, clay and contamination from wash loads have been observed to re-deposit into guar gum residues to stain. Surprisingly, the metase enzyme has been found to hydrolyze hydrocolloid gums, in particular guar gum. This enzymatic hydrolysis leads to the absence of guar gum during washing. Thus, no clay aggregates and clays have full fabric protection potential. In addition, since there is no guar gum residue remaining on the fabric, there is no redeposition and subsequent staining of clay and contamination with the following wash load.
Metase enzyme
An essential component of the laundry detergent and / or textile care composition of the present invention is a metase enzyme.
Three mannanase degrading enzymes are included in the present invention: EC 3.2.1.25:: β-mannosidase, EC 3.2.1.78: endo-1,4-β-mannosidase (hereinafter “mannanase”) And EC 3.2.1.100: 1,4-β-mannobiosidase (IUPAC Taxonomy-Enzyme Nomenclature, 1992 ISBN 0-12-227165-3 Academic Press).
More preferably, the laundry detergent and / or fabric protection composition of the present invention comprises β-1,4-mannosidase (E.C. 3.2.1.78), referred to as a metnanase. The term "mannase" or "galactomannanase" is officially referred to as met endo-1,4-beta-mannosidase and has the alternative names beta-mannase and endo-1,4-mannanase. Refers to a mannanase enzyme defined according to the art which catalyzes the random hydrolysis of 1,4-beta-D-mannodic bonds in galactomannan, glucomannan and galactoglucomannan.
In particular, mannanases (EC 3.2.1.78) constitute a group of polysaccharides that break down mannans and are capable of breaking down the polysaccharide chains containing mannose units, ie mannan, glucomannan, galactomannan and galactogluco- Refers to an enzyme capable of breaking down glycosidic bonds in mannan. Mannan is a polysaccharide with a backbone consisting of β-1,4-linked mannose, glucomannan is a polysaccharide with a backbone or somewhat regular alteration of β-1,4-linked mannose and glucose, and calactomannan And galactoglucomannan are mannan and glucomannan with α-1,6-linked galactose side chains. These compounds can be acetylated.
The degradation of galactomannan and galactoglucomannan is facilitated by complete or partial removal of galactose side chains. In addition, the degradation of acetylated mannan, glucomannan, galactomannan and galactoglucomannan is facilitated by complete or partial deacetylation. Acetyl groups can be removed by alkali or met acetylesterases. The oligomers released from the mannase or by the combination of the mannase with α-galactosidase and / or met acetyl esterase are further degraded and freed by β-mannosidase and / or β-glucosidase. Tods may be released.
Metases are found in some Bacillus organisms. See, eg, Talbot et al., Appl. Environ. Microbiol., Vol. 56, No. 11, pp. 3505-3510 (1990) describe beta-mannanases derived from Bacillus stearotermophilus in the form of dimers having a molecular weight of 162 kDa and an optimal pH of 5.5 to 7.5. It is. See Mendoza et al., World J. Microbiol. Biotech., Vol. 10, No. 5, pp. 551-555 (1994) describe beta-mannanases derived from Bacillus Subtilis having a molecular weight of 38 kDa, optimal activity at pH 5.0 and 55 C, and a pI of 4.8. JP-0304706 describes beta-mannanases derived from Bacillus species with molecular weights of 373 kDa, optimum pH of 8 to 10 and pi of 5.3 to 5.4, as determined by gel filtration. JP 63056289 discloses, for example, alkaline thermostable beta-mannanases that hydrolyze beta-1,4-D-mannopyranoside bonds of mannan and produce manno-oligosaccharides. Manufacturing is described. Document JP 63036774 relates to Bacillus microorganism FERM P-8856, which produces beta-mannanase and beta-mannosidase at alkaline pH. Document JP 08051975 describes alkaline beta-mannanases from alkalophilic Bacillus species AM-001. Purified mannanases from Bacillus amyloliquefaciens useful for bleaching pulp and paper and methods for their preparation are described in WO 97/11164. WO 91/18974 describes hemicellulases such as glucanase, xylanase or mannanase that are active at extreme pH and temperature. WO 94/25576 describes enzymes from Aspergillus aureatus, CBS 101.43, which exhibit mannanase activity that may be useful for the degradation or modification of plant or algal cell wall material. WO 93/24622 describes mannanases isolated from Trichoderma leshi useful for bleaching lignocellulosic pulp.

Justice
Before discussing the invention in more detail, the following terms are first defined.
The term "ortholog" (or "spologue") refers to a polypeptide or protein obtained from one species that is similar to a similar polypeptide or protein from a different species.
The term "paralog" refers to a polypeptide or protein obtained from a given species that is similar to a unique polypeptide or protein from the same species.
The term “expression vector” refers to a linear or cyclic DNA molecule comprising a fragment encoding a polypeptide of interest operably linked to additional fragments provided for transcription. Such additional fragments may include promoter and terminator sequences, and may optionally include one or more origins of replication, one or more optional markers, enhancers, polyadenylation signals, and the like. Expression vectors are generally derived from plasmid or viral DNA or may contain elements of both. The expression vector of the present invention can be any expression vector for convenience in recombinant DNA processes, and the choice of vector can often depend on the host cell into which the vector is introduced. Thus, the vector may be a spontaneous replication vector, ie, a vector, such as a plasmid, in which the replication exists as an extra chromosomal entity that is separate from chromosomal replication. In addition, the vector may be one that, when introduced into the host cell, replicates with the chromosome (s) integrated and integrated into the host cell genome.
The term "recombinant expression" or "recombinant expression" as used herein in the context of expression of a polypeptide or protein is defined according to standard definition in the art. Recombinant expression of the protein is generally performed by using the expression vector defined immediately above.
The term "isolated" means that when applied to a polynucleotide molecule, the polynucleotide is removed from its natural genetic environment so that it does not contain another exogenous or unwanted coding sequence and is intended for use in a genetically operated protein production system. Refers to a suitable form. Such isolated molecules are molecules isolated from their natural environment and include cDNA and genomic clones. Isolated DNA molecules of the invention typically do not contain another gene to which they are associated, but may include naturally occurring 5 'and 3' untranslated regions such as promoters and terminators. Identification of related areas will be apparent to those skilled in the art (Dynan and Tijan, Nature 316: 774-78, 1985).
The term “isolated polynucleotide” may also be referred to as “cloned polynucleotide”. When applied to a protein / polypeptide, the term “isolated” indicates that the protein is found under conditions other than its natural environment. In a preferred form, the isolated protein is substantially free of another protein, especially another analogous protein (ie, "similar impurities" (see below)). It is preferred to provide the protein in at least 40% pure form, more preferably in at least 60% pure form. Even more preferably, as determined by SDS-PAGE, the protein is in highly purified form, ie, at least 80% pure form, more preferably at least 95%, even more preferably at least 99% pure form. It is desirable to provide.
The term “isolated protein / polypeptide” may also be referred to as “purified protein / polypeptide”.
The term “similar impurities” means all impurities that arise from the similar cell from which the polypeptide of the invention is originally obtained (eg, another polypeptide other than the polypeptide of the invention). The term "obtained from" as used herein in connection with a particular microbial source means that the polynucleotide and / or polypeptide is produced by a cell that is inserted by a particular source or into a gene from the source.
When referring to a DNA fragment, the term “operably linked” means that the fragment is aligned such that, for example, transcription begins at the promoter and proceeds to the terminator through the coding fragment so that the fragment functions in accordance with its intended purpose. .
The term "polynucleotide" refers to a single- or double-helix polymer of deoxyribonucleotide or ribonucleotide base that is read from the 5 'to 3' end. Polynucleotides include RNA and DNA and can be isolated from natural sources and synthesized in vitro or produced in combination with natural and synthetic molecules.
The term “complement of polynucleotide molecule” refers to a polynucleotide molecule having a complementary base sequence and a reversible orientation compared to a reference sequence. For example, the sequence 5 'ATGCACGGG 3' is complementary to 5 'CCCGTGCAT 3'.
The term “synonymous nucleotide sequence” refers to a sequence of nucleotides comprising one or more synonymous codons (as compared to a reference polynucleotide molecule encoding a polypeptide). Synonymous codons contain different triplets of nucleotides, but encode the same amino acid residues (ie, the GAU and GAC triplets each encode Asp).
The term “promoter” refers to a portion of a gene containing a DNA sequence provided for binding of RNA polymerase and initiation of transcription. Promoter sequences are typically found in the 5 'noncoding region of a gene, but not always.
The term “secretory signal sequence” refers to a DNA sequence that, as a component of a larger polypeptide, encodes a polypeptide (“secretory peptide”) that is directly linked to the larger polypeptide through the secretory pathway of the cell from which the polypeptide is synthesized. Larger peptides are typically degraded to remove secretory peptides while passing through the secretory pathway.
Methods of Obtaining Another Related Sequence Using Sequences of the Invention:
The sequence information described herein in relation to the polynucleotide sequence encoding the metase of the present invention can be used as a tool to identify another similar metase. For example, polymerase chain reaction (PCR) can be used to amplify a sequence encoding another similar mannanase from various microbial sources, especially from different Bacillus species.

Biol. 224: 899-904, 1992; Wlodaver et al., FEBS Lett. 309: 59-64, 1992. In addition, the identity of essential amino acids can be deduced from analysis of identity with polypeptides related to polypeptides according to the invention.
Multi-amino acid substitutions are known methods of reorganization involving mutagenesis, recombination and / or corresponding screening methods, for example Reidhaar-Olson and Sauer (Science 241: 53-57, 1988), Bowie and Saucer (Proc. Natl. Acad. Sci. USA 86: 2152-2156, 1989), WO 95/17413 or WO 95/22625, can be performed and tested. In summary, these authors describe methods for randomizing two or more positions in a polypeptide at the same time, or for recombination / recombination of different mutants [WO 95/17413, WO 95/22625] following functional polypeptides. Following selection, a method of sequencing the mutated polypeptide to determine the spectrum of acceptable substitutions at each position is described. Another method that can be used is phage display [Lowman et al., Biochem. 30: 10832-10837, 1991; Ladner et al., US Pat. No. 5,223,409; Huse, WIPO Publication WO 92/06204] and region-specific mutagenesis (Derbyshire et al., Gene 46: 145, 1986; Ner et al., DNA 7: 127, 1988].
Mutagenesis / reorganization methods as described above can be combined with high throughput automated screening methods to detect the activity of cloned and mutated polypeptides in host cells. Mutated DNA molecules encoding active polypeptides can be regenerated from host cells and rapidly sequenced using modern devices. These methods allow for the rapid determination of the importance of individual amino acid residues in a desired polypeptide and can be applied to polypeptides of unknown structure. Using the methods described above, one of ordinary skill in the art can identify and / or prepare a variety of polypeptides substantially similar to residues 32 to 343 of SEQ ID NO: 2 and maintain the metase activity of the wild type protein.
Protein manufacturing:
Proteins and polypeptides of the invention, including full length proteins, fragments thereof and fusion proteins, can be prepared in host cells genetically operated according to conventional techniques. Suitable host cells are cell types that can be transformed or transfected using exogenous DNA and grown in media, including bacteria, fungal cells, and cultured highly eukaryotic cells. Preferred are bacterial cells, especially cultured cells of gram-positive microorganisms. Gram-positive cells from Bacillus spp. Are particularly preferred, for example Bacillus subtilis, Bacillus lentus, Bacillus brevis, Bacillus stearotermophilus, Bacillus alcalophilus. alkalophilus, Bacillus amyloquefaciens, Bacillus coagulans, Bacillus circulans, Bacillus lautus, Bacillus thuringiensis, Bacillus richeni Bacillus licheniformis and Bacillus agaradherens, in particular Bacillus agaradherens.
Techniques for manipulating cloned DNA molecules and introducing exogenous DNA into various host cells are described in Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, 1989; Ausubel et al., (Eds.), Current Protocols in Molecular Biology, John Wiley and Sons, Inc., NY, 1987; and "Bacillus subtilis and Other Gram-Positive Bacteria", Sonensheim et al., 1993, American Society for Microbiology, Washington D.C. In general, the DNA sequences encoding the metases of the present invention are operably linked to other genetic elements generally required for their expression, including transcriptional promoters and terminators, in expression vectors. Although those skilled in the art can recognize that within a particular system a selectable marker can be provided for a separate vector and that replication of exogenous DNA can be provided by integration into the host cell genome, the vector It may also typically contain one or more selectable markers and one or more origins of replication. The selection of promoters, terminators, selectable markers, vectors and other elements is a matter of routine design within the level of those skilled in the art. Many of these elements are described in the literature and are available from commercial suppliers.
In order to direct the polypeptide to the secretory pathway of the host cell, a secretory signal sequence (also known as leader sequence, prepro sequence or pre sequence) is provided in the expression vector. The secretory signal sequence can be the sequence of a polypeptide, or can be derived from another secreted protein or newly synthesized. Many suitable secretory signal sequences are known in the art and are described in detail in "Bacillus subtilis and Other Gram-Positive Bacteria", Sonensheim et al., In particular for further description of secretory signal sequences suitable for secretion in Bacillus host cells. , 1993, American Society for Microbiology, Washington DC; And Cutting, S.M. (eds.) "Molecular Biological Methods for Bacillus", John Wiley and Sons, 1990. Secretory signal sequences are involved in the DNA sequence in the correct reading frame. Although specific signal sequences can be located anywhere in the DNA sequence of interest, secretory signal sequences are typically located 5 'to the DNA sequence encoding the polypeptide of interest. Welch et al., US Pat. No. 5,037,743 number; Holland et al., US Pat. No. 5,143,830].
Transformed or transfected host cells are cultured according to conventional methods in a culture medium containing nutrients and other ingredients necessary for the growth of the selected host cell. Various suitable media, including defined media and complex media, are known in the art and generally include carbon sources, nitrogen sources, essential amino acids, vitamins, and minerals. In addition, the medium may contain ingredients such as growth factors or serum, if necessary. In general, growth media is deficient in essential nutrients supplemented with selectable markers performed on, for example, drug selection or expression vectors, or cotransfected into host cells, to cells containing exogenously added DNA. Can be selected.
Protein Isolation:
If the expressed recombinant polypeptide is secreted, the polypeptide can be purified from the growth medium. Preferably, the expression host cell is removed from the medium (eg, by centrifugation) prior to purification of the polypeptide.
If the expressed recombinant polypeptide is not secreted from the host cell, the host cell is preferably degraded and the polypeptide is released into an aqueous “extract” which is the first step in this purification technique. Preferably, the expression host cell is recovered from the medium (eg, by centrifugation) prior to cell degradation.
Cytolysis can be performed by conventional techniques such as lysosomal digestion or pressing of cells via high pressure. For further explanation of these cell lysis techniques, see Robert K. Scobes, Protein Purification, Second edition, Springer-Verlag.
Depending on whether the expressed recombinant polypeptide is secreted or not, it can be fractionated and / or purified using conventional purification methods and media.
Ammonium sulfate precipitation and acid or chaotrope extraction can be used for fractionation of the samples. Exemplary tableting steps can include hydroxyapatite, size extrusion, FPLC, and reversible phase high performance liquid chromatography. Suitable anion exchange media include derivatized dextran, agarose, cellulose, polyacrylamide, special silica and the like. PEI, DEAE, QAE and Q derivatives are preferred, DEAE Fast-Flow Sepharose (PharmaPharma, Piscataway, NJ) is particularly preferred. Exemplary chromatographic media are media derived using phenyl, butyl or octyl groups, for example phenyl-sepharose FF from Pharmacia, Toyopearl butyl 650 from Toso Haas, Montgomeryville. , PA], octyl-sepharose [manufacturer; Pharmacia] and the like; Or polyacrylic acid resins such as Amberchrom CG 71 (Toso Haas) and the like. Suitable solid supports include glass beads, silica-based resins, cellulosic resins, agarose beads, crosslinked agarose beads, polystyrene beads, crosslinked polyacrylamide resins, and the like, which are insoluble under the conditions used. These supports may be modified using reactive groups that allow for the attachment of proteins by amino groups, carboxyl groups, sulfhydryl groups, hydroxy groups and / or carbohydrate moieties. Examples of coupling chemicals include carboxyl for cyanogen bromide actives, N-hydroxysuccinimide actives, epoxide actives, sulfhydryl actives, hydrazide actives, and carbodiimide coupling chemicals. And amino derivatives. These and other solid media are well known and widely used in the art and are available from commercial suppliers.
The choice of a particular method is a matter of everyday design and is in part determined by the nature of the chosen support. Reference: Affinity Chromatography: Principles & Methods, Pharmacia LKB Biotechnology, Uppsala, Sweden, 1988.

In addition to an enzyme core comprising a catalytic moiety, the enzyme of the present invention includes a cellulose binding moiety (CBD), a cellulose binding moiety of an enzyme that is possibly bound, and an enzyme core (catalytically active moiety). The cellulose binding site (CBD) can be present as an integral part of the encoded enzyme or CBD from another origin can be introduced into the enzyme to form an enzyme hybrid. As used herein, the "cellulose binding site" is described by Peter Tomme et al. In "Cellulose-Binding Domains: Classification and Properties" in "Enzyme Degradation of Insoluble Carbohydrates", John N. Saddler and Michael H. Penner. (Eds.), ACS Symposium Series, No. 618, 1996]. In this definition, 120 cellulose-binding sites are classified into 10 species (IX) and CBD is found in various enzymes such as cellulase, xylanase, mannanase, arabinofuranosidase, acetyl esterase and chitinase. Indicates. CBD has also been found in egg ash (e.g., red agar porphyra pulpurea as a non hydrolyzable polysaccharide-binding protein) (Tomme et al., Op.cit.). However, most CBDs are from cellulase and xylanase and CBDs are found at or inside the N and C termini of the protein. Enzyme hybrids are known in the art (see WO 90/00609 and WO 95/16782), and in the presence or absence of a binder, one or more DNAs encoding cellulose binding sites bound to a DNA sequence encoding a mannase enzyme. DNA constructs comprising fragments can be prepared by transforming host cells and growing host cells to express the fused gene. Enzyme hybrids are of the formula CBD-MR-X, where CBD is the N-terminal or C-terminal portion of the amino acid sequence corresponding at least to the cellulose-binding site; MR is the middle region (conjugate), and is bound or preferably carbon number About 2 to about 100, more preferably a short bond group of 2 to 40 carbon atoms, or preferably about 2 to about 100 amino acids, more preferably 2 to 40 amino acids; It is N-terminal or C-terminal region of the enzyme).
The enzymes described above may be present in any of the suitable origins, such as plant, animal, bacterial, fungal and yeast origin. The origin may further be mesophilic or cryogenic (frozen, non-cold, thermophilic, hypertonic, alkaline, eosinophil, basophilic, etc.). Such enzymes in purified or unpurified form may be used. Recently, modification of wild-type enzymes through protein / genetic engineering techniques is generally practiced to optimize performance efficiency in the cleaning compositions of the present invention. For example, variants can be designed to increase the compatibility of enzymes with components generally present in such compositions. Alternatively, the variant can be designed to suit the particular cleaning application by adjusting the optimum pH, bleaching or chelate stability, catalytic activity, etc. of the enzyme variant.
In particular, in the case of bleaching stability, the surface charge for amino acid and surfactant compatibility that is sensitive to oxygen should be focused. The isoelectric point of such enzymes can be modified by substitution of some charged amino acids, for example increasing the isoelectric point can help to increase the compatibility with anionic surfactants. The stability of the enzyme can be further enhanced, for example, by the formation of additional metal binding sites to increase salt binding and chelate stability.

In addition, the stability of the enzyme can be enhanced by, for example, generating additional salt bridges or strengthening calcium binding sites to increase the stability of the chelating agent. Most cellulase has a separate binding region (CBD), so special attention should be paid to the cellulase. These regions can be altered to change the properties of these enzymes.
The enzyme is generally incorporated into the laundry detergent and / or fabric protection composition in a pure enzyme in an amount of 0.0001% to 2% by weight of the laundry detergent and / or fabric protection composition.
