'''Pyranose oxidase''' or '''pyranose 2-oxidase''' (P2O) catalyzes the conversion of D-glucose and molecular oxygen to 2-dehydro-D-glucose and H<sub>2</sub>O<sub>2</sub>. It is abundant in lignin-degrading white rot fungi. P2O is a <scene name='70/708805/Cv/2'>tetramer</scene> flavoprotein containing the <scene name='70/708805/Cv/3'>prosthetic group FAD in each monomer</scene>. P2O oxidizes several aldopyranoses with the preferred electron donors being D-glucose, D-xylose and D-sorbose<ref>PMID:11152063</ref>. | '''Pyranose oxidase''' or '''pyranose 2-oxidase''' (P2O) catalyzes the conversion of D-glucose and molecular oxygen to 2-dehydro-D-glucose and H<sub>2</sub>O<sub>2</sub>.
