IUBMB Enzyme Nomenclature

EC 1.2.5.2

Accepted name: aldehyde dehydrogenase (quinone)

Reaction: an aldehyde + a quinone + H2O = a carboxylate + a quinol

Other name(s): aldehyde dehydrogenase (acceptor)

Systematic name: aldehyde:quinone oxidoreductase

Comments: Wide specificity; acts on straight-chain aldehydes up to C10, aromatic aldehydes, glyoxylate and glyceraldehyde. The enzymes contains a PQQ cofactor and multiple hemes that deliver the electrons to the membrane quinone pool.
