In enzymology, a 3-oxoacyl-[acyl-carrier-protein] reductase is an enzyme that catalyzes the chemical reaction 3-oxoacyl-[acyl-carrier-protein] + NADPH + H+ ⇌ {\displaystyle \rightleftharpoons } -3-hydroxyacyl-[acyl-carrier-protein] + NADP+This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group as hydride donor with NAD+ or NADP+ as hydride acceptor.
