Definitions

  • the present invention relates to newly identified lytic polysaccharide monooxygenases (LPMOs) and their use in detergent compositions, in particular as enhancers of enzyme detergency benefits in detergents, as well as detergent compositions comprising said LPMOs, optionally in combination with other enzymes.
  • the invention also relates to a process of washing a fabric or hard surface using the LPMOs alone or in combination with one or more enzymes and/or with the detergents of the present invention.
  • a further aspect of the invention relates to the isolated LPMO polypeptides and isolated polynucleotides encoding the polypeptides as well as to vectors and host cells comprising the polynucleotides and methods of producing the polypeptides.
  • Lytic polysaccharide monooxygenases belong to a class of proteins that assist in the degradation of crystalline polymeric carbohydrate substrates (EC 1.14.99.53/54/55/56). They are copper-de- pendent enzymes that catalyze oxidative cleavage of glycosidic bonds in polysaccharides such as chitin, cellulose, and starch in the presence of a reductant and oxygen.
  • LPMOs can utilize a vast variety of electron donors (reductants), including small phenolic compounds and partner enzymes such as cellobiose dehydrogenase (Stepnov, A. A., Forsberg, Z., Sorlie, M. et al.
  • LPMOs act on highly crystalline substrate surfaces, rather than on isolated polysaccharide chains within amorphous regions. LPMOs are classified in the Carbohydrate-Active EnZymes database (CAZy) into eight auxiliary activity (AA) families including AA9 (formerly glycosyl hydrolase family 61 , GH61), AA10 (formerly carbohydrate-binding module family 33, CBM33), AA11 and AA13-AA17 enzymes. In insects the gene family encoding LPMO-like proteins has been identified recently and determined to belong to the AA15 family (LPMO15) (Sabbadin et al, NATURE COMMUNICATIONS (2016) 9:756).
  • CAZy Carbohydrate-Active EnZymes database
  • LPMOs are known to play a pivotal role in the breakdown of polysaccharides such as cellulose and chitin, by catalyzing the oxidative, as opposed to hydrolytic, cleavage of glycosidic bonds. In this way, the initial chemical and physical recalcitrance of the polysaccharide is overcome, thereby making the substrate tractable to hydrolases.
  • LPMOs belonging to the AA9 familiy have been widely used in industry, e.g., in baking (WO 04/031378), in the conversion of cellulosic feedstock into ethanol (WO 07/089290) and the use in laundry detergent has also been proposed (WO 2011/080267).
  • the present invention concerns lytic polysaccaharide monooxygenase that in addition to LPMO activity also have keratinase activity, and to their use, in particular use in detergents.
  • LPMOs of the present invention belong to the AA15 enzymes and the inventors of the present invention have surprisingly found that these new LPMOs not only act on polymeric carbohydrates, such as chitin, but also on protein making them very useful in detergents that are applied for the removal various types of stains, such as proteins, starch, mannan and (hemi)cellulose.
  • stains such as proteins, starch, mannan and (hemi)cellulose.
  • Keratin is a protein that helps form hair, nails and the skin's outer layer and is easily accumulate on clothes.
  • Alpha-keratin is a fibrous structural protein made up of amino acids that form a repeating secondary structure.
  • the secondary structure of alpha-keratin provides a tightly wound structure and makes it one of the strongest biological materials and very hard to break down.
  • the LPMOs of the present invention open the fibrious structure of the keratin making it accessible to the further breakdown of the protein to smaller polypeptides by proteases.
  • the LPMOs of the present invention also have activity on polysaccharides, such as chitin, and are believed to work in a similar way as described for the activity on protein, i.e. making the glycosidic substrate accessible to glycoside hydrolases, such as cellulases and mannanases as well as amylases.
  • the LPMOs of the present invention thus have a dual activity as they act both on proteins and carbohydrates that otherwise are hard to access, allowing for the further breakdown of the substrate by hydrolytic enzymes such as proteases, amylases and glycosyl hydrolases making them beneficial in the removal of stains from objects (e.g. fabrics and hard surfaces).
  • hydrolytic enzymes such as proteases, amylases and glycosyl hydrolases making them beneficial in the removal of stains from objects (e.g. fabrics and hard surfaces).

  • the LPMO polypeptide used in the present invention has a cysteine activity of at least 0.01 absorbance units after 23 hours incubation with SEQ ID NO: 11 compared to SEQ ID NO: 11 alone (control).
  • Enzymes were added to each bottle according to Table 2 below. Wash was started by closing the bottle lids and placing closed bottles within Wascator FOM71 CLS (Electrolux) which used 25 L water to exercise the closed bottles during the wash time.
  • wash performance is expressed as a delta remission measured value (ARem).
  • ARem delta remission measured value
  • Delta remission values for individual swatches are calculated by subtracting the remission value at 460 nm of the control swatch from the remission value at 460 nm of the washed swatch. Calculating the enzyme effect is done by taking the measurements from washed swatches with enzymes and subtract with the measurements from washed without enzyme for each stain. The total enzyme performance is calculated as the average of individual ARem.
  • Table 2 Wash effects of LPMO on Consumertec sebum swatches. Delta values are based on subtracting the wash effects of the detergent alone.
  • Example 6 Enzymatic effects on sebum removal during wash in the presence of ascorbic acid and enzyme blend
  • Example 5 The same test conditions as in Example 5 above was applied, except that ascorbic acid was added as electron donor and the effect of combination of LPMO and commercially available enzyme blend Medley Brilliant 100L was added.
  • Table 3 Wash effects of LPMO on Consumertec sebum swatches. Delta values are based on subtracting the wash effects of the detergent alone. Ascorbic acid is added as a reductant. Commercially available enzyme blend Medley Brilliant 100L (available from Novozymes A/S) is added to assist removal of sebum.
  • Medley Brilliant 100L is a commercially available enzyme blend of protease (subtilisin), alpha-amylase, pectate lyase, mannanase (mannan endo- beta-1 , 4-mannosidase), cellulase and lipase enzymes from Novozymes A/S.
