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 acyl-carrier-protein reductase (ambiguous); enoyl-ACP reductase (ambiguous); acyl-[acyl-carrier-protein]:NADP+ oxidoreductase (B-specific); acyl-[acyl-carrier protein]:NADP+ oxidoreductase (B-specific); enoyl-[acyl-carrier-protein] reductase (NADPH, B-specific)
Systematic name: acyl-[acyl-carrier protein]:NADP+ oxidoreductase (Si-specific)
Comments: One of the activities of EC 126.96.36.199, fatty-acyl-CoA synthase system, an enzyme found in yeasts (Ascomycota and Basidiomycota). Catalyses the reduction of enoyl-acyl-[acyl-carrier protein] derivatives of carbon chain length from 4 to 16. The yeast enzyme is Si-specific with respect to NADP+. cf. EC 188.8.131.52, enoyl-[acyl-carrier-protein] reductase (NADPH, Re-specific) and EC 184.108.40.206, enoyl-[acyl-carrier-protein] reductase (NADPH), which describes enzymes whose stereo-specificity towards NADPH is not known. See also EC 220.127.116.11, enoyl-[acyl-carrier-protein] reductase (NADH).
