Accepted name: acetaldehyde dehydrogenase (acetylating)
Reaction: acetaldehyde + CoA + NAD+ = acetyl-CoA + NADH + H+

Other name(s): aldehyde dehydrogenase (acylating); ADA; acylating acetaldehyde dehyrogenase; DmpF; BphJ
Systematic name: acetaldehyde:NAD+ oxidoreductase (CoA-acetylating)
Comments: Also acts, more slowly, on glycolaldehyde, propanal and butanal. In several bacterial species this enzyme forms a bifunctional complex with EC, 4-hydroxy-2-oxovalerate aldolase. The enzymes from the bacteria Burkholderia xenovorans and Thermus thermophilus also perform the reaction of EC, propanal dehydrogenase (propanoylating). Involved in the meta-cleavage pathway for the degradation of phenols, methylphenols and catechols. NADP+ can replace NAD+ but the rate of reaction is much slower [3].
