Accepted name: enoyl-[acyl-carrier-protein] reductase (NADPH)
Reaction: an acyl-[acyl-carrier protein] + NADP+ = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADPH + H+
Other name(s): acyl-ACP dehydrogenase (ambiguous); enoyl-[acyl carrier protein] (reduced nicotinamide adenine dinucleotide phosphate) reductase; NADPH 2-enoyl Co A reductase; enoyl-ACP reductase (ambiguous); fabL (gene name)
Systematic name: acyl-[acyl-carrier protein]:NADP+ oxidoreductase
Comments: The 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 the acyl-carrier protein, in an NADPH-dependent manner. This entry stands for enzymes whose stereo-specificity with respect to NADP+ is not known. [cf. EC enoyl-[acyl-carrier-protein] reductase (NADPH, Re-specific), EC, enoyl-[acyl-carrier-protein] reductase (NADPH, Si-specific) and EC, enoyl-[acyl-carrier-protein] reductase (NADH)].
