IUBMB Enzyme Nomenclature


Accepted name: formaldehyde dismutase

Reaction: 2 formaldehyde + H2O = formate + methanol

Other name(s): aldehyde dismutase; cannizzanase; nicotinoprotein aldehyde dismutase

Systematic name: formaldehyde:formaldehyde oxidoreductase

Comments: The enzyme contains a tightly but noncovalently bound NADP(H) cofactor, as well as Zn2+ and Mg2+. Enzyme-bound NADPH formed by oxidation of formaldehyde to formate is oxidized back to NADP+ by reaction with a second formaldehyde, yielding methanol. The enzyme from the bacterium Mycobacterium sp. DSM 3803 also catalyses the reactions of EC, alcohol dehydrogenase (nicotinoprotein) and EC, methanol dehydrogenase (nicotinoprotein) [3]. Formaldehyde and acetaldehyde can act as donors; formaldehyde, acetaldehyde and propanal can act as acceptors [1,2].
