In enzymology, an enoyl-[acyl-carrier-protein] reductase is an enzyme that catalyzes the chemical reaction acyl-[acyl-carrier-protein] + NADP+ ⇌ {\displaystyle \rightleftharpoons } trans-2,3-dehydroacyl-[acyl-carrier-protein] + NADPH + H+Thus, the two substrates of this enzyme are [[acyl-[acyl-carrier-protein]]] and NADP+, whereas its 3 products are [[trans-2,3-dehydroacyl-[acyl-carrier-protein]]], NADPH, and H+.
