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+.
This enzyme belongs to the family of oxidoreductases, to be specific, those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is acyl-[acyl-carrier-protein]:NADP+ oxidoreductase (A-specific). Other names in common use include acyl-ACP dehydrogenase, enoyl-[acyl carrier protein] (reduced nicotinamide adenine, dinucleotide phosphate) reductase, NADPH 2-enoyl Co A reductase, enoyl-ACp reductase, and enoyl-[acyl-carrier-protein] reductase (NADPH2, A-specific).
