Chitooligosaccharide oxidase

UniProtKB accession:  I1S2K2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the selective oxidation of C1 hydroxyl moieties on chitooligosaccharides with concomitant reduction of molecular oxygen to hydrogen peroxide. This results in the formation of the corresponding lactones, which typically undergo spontaneous hydrolysis. Chitooligosaccharides are homo- or heterooligomers of N-acetylglucosamine (GlcNAc) and D-glucosamine which are linked through beta-1,4-glycosidic bonds. For optimal substrate binding at least 2 GlcNAc units are needed, and chitooligosaccharide oxidase is most efficient on chitobiose, chitotriose and chitotetraose.
