3(or 17)-alpha-hydroxysteroid dehydrogenase.
based on mapping to UniProt Q91WR5
Androsterone + NAD(P)(+) = 5-alpha-androstane-3,17-dione + NAD(P)H.
-!- Acts on the 3-alpha-hydroxy group of androgens of the 5-alpha- androstane series; and also, more slowly, on the 17-alpha-hydroxyl group of both androgenic and estrogenic substrates (cf. EC 1.1.1.51).
