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.
