IUBMB Enzyme Nomenclature

EC 1.1.3.13

Accepted name: alcohol oxidase

Reaction: a primary alcohol + O2 = an aldehyde + H2O2

Other name(s): ethanol oxidase

Systematic name: alcohol:oxygen oxidoreductase

Comments: The enzymes from the fungi Candida methanosorbosa and several Basidiomycetes species contain an FAD cofactor [1,3]. The enzyme from the phytopathogenic fungi Colletotrichum graminicola and Colletotrichum gloeosporioides utilize a mononuclear copper-radical mechanism [4]. The enzyme acts on primary alcohols and unsaturated alcohols, and has much lower activity with branched-chain and secondary alcohols.
