3-oxoacyl-(acyl-carrier-protein) reductase

In enzymology, a 3-oxoacyl- reductase () is an enzyme that catalyzes the chemical reaction

(3R)-3-hydroxyacyl- + NADP⁺ <math>rightleftharpoons</math> 3-oxoacyl- + NADPH + H⁺

Thus, the two substrates of this enzyme are -3-hydroxyacyl- and NADP⁺, whereas its 3 products are 3-oxoacyl-, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (3R)-3-hydroxyacyl-:NADP+ oxidoreductase. Other names in common use include beta-ketoacyl-(ACP) reductase, beta-ketoacyl acyl carrier protein (ACP) reductase, beta-ketoacyl reductase, beta-ketoacyl thioester reductase, beta-ketoacyl-ACP reductase, beta-ketoacyl-acyl carrier protein reductase, 3-ketoacyl acyl carrier protein reductase, NADPH-specific 3-oxoacyl-reductase, and 3-oxoacyl-reductase. This enzyme participates in fatty acid biosynthesis and polyunsaturated fatty acid biosynthesis.
