(R) 3 hydroxyacid ester dehydrogenase

In enzymology, a (R)-3-hydroxyacid-ester dehydrogenase (EC 1.1.1.279) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ethyl (R)-3-hydroxyhexanoate and NADP⁺, whereas its 3 products are ethyl 3-oxohexanoate, 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 ethyl-(R)-3-hydroxyhexanoate:NADP⁺ 3-oxidoreductase. This enzyme is also called 3-oxo ester (R)-reductase.
