Auxiliary Activity Family 10

Activities in Family	AA10 (formerly CBM33) proteins are copper-dependent lytic polysaccharide monooxygenases (LPMOs); some proteins have been shown to act on chitin, others on cellulose; 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); lytic xylan monooxygenase / xylan oxidase (glycosidic bond-cleaving) (EC 1.14.99.-)
Mechanism	monooxygenase
Note	AA10 (formerly CBM33). The enzymes in this family were originally classified as chitin-binding proteins (CBM33); Vaaje-Kolstad et al. have shown that these proteins are in fact oxidative enzymes [PMID - 20929773]. They are now reclassified in the AA category of CAZy. Because a significant literature is associated with the old name CBM33, we recommend to describe these enzymes as "AA10 (formerly CBM33)".
