DE   3alpha-hydroxysteroid dehydrogenase (Re-specific).
AN   3alpha-hydroxysteroid dehydrogenase.
AN   3alpha-hydroxysteroid dehydrogenase (A-specific).
CA   (1) a 3alpha-hydroxysteroid + NAD(+) = a 3-oxosteroid + H(+) + NADH.
CA   (2) a 3alpha-hydroxysteroid + NADP(+) = a 3-oxosteroid + H(+) + NADPH.
CC   -!- The enzyme acts on multiple 3alpha-hydroxysteroids.
CC   -!- Re-specific with respect to NAD(+) or NADP(+) (cf. EC 1.1.1.50).
CC   -!- Enzymes whose stereo-specificity with respect to NAD(+) or NADP(+) is
CC       not known are described by EC 1.1.1.357.
