General annotation (Comments)

Function

Catalyzes the conversion of aldehydes and ketones to alcohols. Catalyzes the reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ) and the oxidation of 9-alpha,11-beta-PGF2 to PGD2. Functions as a bi-directional 3-alpha-, 17-beta- and 20-alpha HSD. Can interconvert active androgens, estrogens and progestins with their cognate inactive metabolites. Preferentially transforms androstenedione (4-dione) to testosterone By similarity.

Catalytic activity

Trans-1,2-dihydrobenzene-1,2-diol + NADP(+) = catechol + NADPH.

Androsterone + NAD(P)(+) = 5-alpha-androstane-3,17-dione + NAD(P)H.

(5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate + NADP(+) = (5Z,13E)-(15S)-9-alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate + NADPH.

Testosterone + NAD(+) = androst-4-ene-3,17-dione + NADH.

Testosterone + NADP(+) = androst-4-ene-3,17-dione + NADPH.

Sequence similarities

Belongs to the aldo/keto reductase family.
