Lytic polysaccharide mono-oxygenase, cellulose-degrading. This domain is found associated with a wide variety of cellulose binding domains. This is a family of two very closely related proteins that together act as both a C1- and a C4-oxidising lytic polysaccharide mono-oxygenase, degrading cellulose. This domain is also found in baculoviral spheroidins and spindolins, protein of unknown function.
lytic polysaccharide monooxygenase (LPMO) auxiliary activity family 10 (AA10). AA10 proteins are copper-dependent lytic polysaccharide monooxygenases (LPMOs), which may act on chitin or cellulose. The family used to be called CBM33. Activities in this family include lytic cellulose monooxygenase (C1-hydroxylating) (EC 1.14.99.54), lytic cellulose monooxygenase (C4-dehydrogenating) (EC 1.14.99.56), lytic chitin monooxygenase (EC 1.14.99.53), and lytic xylan monooxygenase/xylan oxidase (glycosidic bond-cleaving) (EC 1.14.99.-). Also included are viral chitin-binding glycoproteins such as fusolin and spheroidin-like proteins.
