3 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 2

Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity 3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids.
