Function and Biology Details

Reactions catalysed:
A 3-alpha-hydroxysteroid + NAD(P)(+) = a 3-oxosteroid + NAD(P)H
Testosterone + NAD(+) = androstenedione + NADH
Indan-1-ol + NAD(P)(+) = indanone + NAD(P)H
Trans-1,2-dihydrobenzene-1,2-diol + NADP(+) = catechol + NADPH
(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 + NADP(+) = androst-4-ene-3,17-dione + NADPH
