SYSTEMATIC NAME
IUBMB Comments
acyl-[acyl-carrier protein]:NADP+ oxidoreductase (Si-specific)
One of the activities of EC 2.3.1.86, fatty-acyl-CoA synthase, an enzyme found in yeasts (Ascomycota and the 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 1.3.1.39, enoyl-[acyl-carrier-protein] reductase (NADPH, Re-specific) and EC 1.3.1.104, enoyl-[acyl-carrier-protein] reductase (NADPH), which describes enzymes whose stereo-specificity towards NADPH is not known. See also EC 1.3.1.9, enoyl-[acyl-carrier-protein] reductase (NADH).
