IntEnz Enzyme Nomenclature


Accepted name:
carbonyl reductase (NADPH)
Other names:
NADPH2-dependent carbonyl reductase
aldehyde reductase 1
carbonyl reductase
nonspecific NADPH-dependent carbonyl reductase
prostaglandin 9-ketoreductase
xenobiotic ketone reductase
Systematic name:
secondary-alcohol:NADP+ oxidoreductase



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+)].
