EC 1.2.1.87 Details
EC number
1.2.1.87
Accepted name
propanal dehydrogenase (CoA-propanoylating)
Reaction
propanal + CoA + NAD+ = propanoyl-CoA + NADH + H+
Other name(s)
BphJ
Systematic name
propanal:NAD+ oxidoreductase (CoA-propanoylating)
Comment
The enzyme forms a bifunctional complex with EC 4.1.3.43, 4-hydroxy-2-oxohexanoate aldolase, with a tight channel connecting the two subunits [1,2,3]. Also acts, more slowly, on glycolaldehyde and butanal. In Pseudomonas species the enzyme forms a bifunctional complex with EC 4.1.3.39, 4-hydroxy-2-oxovalerate aldolase. The enzymes from the bacteria Burkholderia xenovorans and Thermus thermophilus also perform the reaction of EC 1.2.1.10, acetaldehyde dehydrogenase (acetylating). NADP+ can replace NAD+ with a much slower rate [3].
