EC number
1.1.3.40
Accepted name
D-mannitol oxidase

D-mannitol + O2 = D-mannose + H2O2
Other name(s)
mannitol oxidase, D-arabitol oxidase
Systematic name
mannitol:oxygen oxidoreductase (cyclizing)
CAS registry number
73562-29-5
Comment
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.
