Reaction: ethyl (R)-3-hydroxyhexanoate + NADP+ = ethyl 3-oxohexanoate + NADPH + H+
Other name(s): 3-oxo ester (R)-reductase
Systematic name: ethyl-(R)-3-hydroxyhexanoate:NADP+ 3-oxidoreductase
Comments: Also acts on ethyl (R)-3-oxobutanoate and some other (R)-3-hydroxy acid esters. The (R)- symbol is allotted on the assumption that no substituents change the order of priority from O-3 > C-2 > C-4. A subunit of yeast fatty acid synthase EC 184.108.40.206, fatty-acyl-CoA synthase system. cf. EC 220.127.116.110, (S)-3-hydroxyacid ester dehydrogenase.
