IUBMB Enzyme Nomenclature


Accepted name: enoyl-[acyl-carrier-protein] reductase (NADPH, Re-specific)

Reaction: an acyl-[acyl-carrier protein] + NADP+ = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADPH + H+

Other name(s): acyl-ACP dehydrogenase; enoyl-[acyl carrier protein] (reduced nicotinamide adenine dinucleotide phosphate) reductase; NADPH 2-enoyl Co A reductase; enoyl-ACp reductase; enoyl-[acyl-carrier-protein] reductase (NADPH2, A-specific); acyl-[acyl-carrier-protein]:NADP+ oxidoreductase (A-specific); enoyl-[acyl-carrier-protein] reductase (NADPH, A-specific); acyl-[acyl-carrier protein]:NADP+ oxidoreductase (A-specific)

Systematic name: acyl-[acyl-carrier protein]:NADP+ oxidoreductase (Re-specific)

Comments: This enzyme completes each cycle of fatty acid elongation by catalysing the stereospecific reduction of the double bond at position 2 of a growing fatty acid chain, while linked to an acyl-carrier protein. It is one of the activities of EC, fatty-acid synthase system. The mammalian enzyme is Re-specific with respect to NADP+. cf. EC, enoyl-[acyl-carrier-protein] reductase (NADPH, Si-specific) and EC, enoyl-[acyl-carrier-protein] reductase (NADPH).
