HSD3B2 iso2 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. Belongs to the 3-beta-HSD family. Expressed in adrenal gland, testis and ovary. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
