Function
Catalyzes the selective oxidation of C1 hydroxyl moieties on mono-, oligo- and polysaccharides with concomitant reduction of molecular oxygen to hydrogen peroxide. This results in the formation of the corresponding lactones, which typically undergo spontaneous hydrolysis. Carbohydrate oxidase is able to oxidize a variety of substrates including D-glucose, D-galactose, D-xylose, D-maltose, D-cellobiose, and lactose. In addition, among various oligosaccharides, the enzyme preferred tetrameric dextrins, indicating a favorable interaction of four linked glucose units with the substrate binding pocket.
