KEGG   ENZYME: 1.1.1.279
Entry
EC 1.1.1.279                Enzyme                                 
Name
(R)-3-hydroxyacid-ester dehydrogenase;
3-oxo ester (R)-reductase
Class
Oxidoreductases;
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
Sysname
ethyl-(R)-3-hydroxyhexanoate:NADP+ 3-oxidoreductase
Reaction(IUBMB)
ethyl (R)-3-hydroxyhexanoate + NADP+ = ethyl 3-oxohexanoate + NADPH + H+ [RN:R04105]
Reaction(KEGG)
R04105
Substrate
ethyl (R)-3-hydroxyhexanoate [CPD:C03864];
NADP+ [CPD:C00006]
Product
ethyl 3-oxohexanoate [CPD:C02975];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
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 2.3.1.86, fatty-acyl-CoA synthase system. cf. EC 1.1.1.280, (S)-3-hydroxyacid ester dehydrogenase.
History
EC 1.1.1.279 created 1990 as EC 1.2.1.55, transferred 2003 to EC 1.1.1.279, modified 2018
