Pyranose 2-oxidase (P2O, EC 1.1.3.10) is a GMC-type (glucose–methanol–choline) oxidase. The enzyme catalyzes the oxidation of d-glucose and other aldopyranoses at the C2 position, yielding the corresponding ketoaldoses. Pyranose 2-oxidase has been isolated from a number of wood-degrading white-rot basidiomycetes.[‌102‌] The native enzyme is a homotetramer of 280 kDa, with each subunit containing one molecule of flavin adenine dinucleotide (FAD), which is covalently linked to a histidine residue.[‌103‌]
