DE   3(or 17)alpha-hydroxysteroid dehydrogenase.
CA   (1) androsterone + NADP(+) = 5alpha-androstan-3,17-dione + H(+) + NADPH.
CA   (2) androsterone + NAD(+) = 5alpha-androstan-3,17-dione + H(+) + NADH.
CC   -!- Acts on the 3alpha-hydroxy group of androgens of the 5alpha-
CC       androstane series; and also, more slowly, on the 17alpha-hydroxyl
CC       group of both androgenic and estrogenic substrates (cf. EC 1.1.1.51).
