Auxiliary Activity Family 9

Activities in FamilyAA9 (formerly GH61) proteins are copper-dependent lytic polysaccharide monooxygenases (LPMOs); cleavage of cellulose chains with oxidation of various carbons (C-1, C-4 and C-6) has been reported several times in the literature;
Mechanism monooxygenase
NoteAA9 (formerly GH61). The enzymes in this family were originally classified as a glycoside hydrolases (GH61) based on very weak endo-1,4-b-D-glucanase activity in one family member. They are now reclassified in the AA category of CAZy. Because a significant literature is associated with the old name GH61, we recommend to describe these enzymes as "AA9 (formerly GH61)".
