Accepted name: 3(or 17)β-hydroxysteroid dehydrogenase

Reaction: testosterone + NAD(P)+ = androstenedione + NAD(P)H + H+

Glossary: androstenedione = androst-4-ene-3,17-dione

Other name(s): β-hydroxy steroid dehydrogenase; 17-ketoreductase; 17β-hydroxy steroid dehydrogenase; 3β-hydroxysteroid dehydrogenase; 17β-hydroxy steroid dehydrogenase; 3β-hydroxy steroid dehydrogenase

Systematic name: 3(or 17)β-hydroxysteroid:NAD(P)+ oxidoreductase

Comments: Also acts on other 3β- or 17β-hydroxysteroids. cf. EC 3(or 17)α-hydroxysteroid dehydrogenase.
