IUBMB Enzyme Nomenclature


Accepted name: carbonyl reductase (NADPH)

Reaction: R-CHOH-R' + NADP+ = R-CO-R' + NADPH + H+

Other name(s): aldehyde reductase 1; prostaglandin 9-ketoreductase; xenobiotic ketone reductase; NADPH2-dependent carbonyl reductase; ALR3; carbonyl reductase; nonspecific NADPH-dependent carbonyl reductase; carbonyl reductase (NADPH2)

Systematic name: secondary-alcohol:NADP+ oxidoreductase

Comments: Acts on a wide range of carbonyl compounds, including quinones, aromatic aldehydes, ketoaldehydes, daunorubicin and prostaglandins E and F, reducing them to the corresponding alcohol. Si--specific with respect to NADPH [cf. EC alcohol dehydrogenase (NADP+)].
