EC 1.1.3.40     
Accepted name: D-mannitol oxidase
Reaction: D-mannitol + O2 = D-mannose + H2O2
Other name(s): mannitol oxidase; D-arabitol oxidase
Systematic name: mannitol:oxygen oxidoreductase (cyclizing)
Comments: Also catalyses the oxidation of D-arabinitol and, to a lesser extent, D-glucitol (sorbitol), whereas L-arabinitol is not a good substrate. The enzyme from the snails Helix aspersa and Arion ater is found in a specialised tubular organelle that has been termed the mannosome.
