IUBMB Enzyme Nomenclature


Accepted name: long-chain acyl-[acyl-carrier-protein] reductase

Reaction: a long-chain aldehyde + an [acyl-carrier protein] + NAD(P)+ = a long-chain acyl-[acyl-carrier protein] + NAD(P)H + H+

Glossary: a long-chain aldehyde = a fatty aldehyde
acyl-carrier protein = ACP = [acp]

Other name(s): long-chain acyl-[acp] reductase; fatty acyl-[acyl-carrier-protein] reductase; acyl-[acp] reductase

Systematic name: long-chain-aldehyde:NAD(P)+ oxidoreductase (acyl-[acyl-carrier protein]-forming)

Comments: Catalyses the reaction in the opposite direction. This enzyme, purified from the cyanobacterium Synechococcus elongatus PCC 7942, catalyses the NAD(P)H–dependent reduction of an activated fatty acid (acyl-[acp]) to the corresponding aldehyde. Together with EC, octadecanal decarbonylase, it is involved in alkane biosynthesis. The natural substrates of the enzyme are C16 to C18 activated fatty acids. Requires Mg2+.
