Common Name

21-Hydroxypregnenolone

Description

21-hydroxypregnenolone is an essential intermediate in corticosterone synthesis. The hydrolysis of 21-hydroxypregnenolone of fetal origin by steryl-sulfatase (SOS, EC 3.1.6.2), may be important in the biosynthesis of deoxycorticosterone, which is present in the plasma of pregnant women in high concentration. 21-hydroxypregnenolone has been identified in follicular fluid from follicles of women. Pregnenolone is transformed to 21-hydroxypregnenolone by human adrenal microsomal preparations, suggesting the involvement of alternative paths via 17a,21-dihydroxypregnenolone in human.

Enzymes

Enzyme Details

1. 3 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 1

General function:: Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity
Specific function:: 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. Efficiently catalyzes the transformation of pregnenolone to progesterone, 17-alpha-hydroxypregnenolone to 17-alpha-hydroxyprogesterone, DHEA to 4-androstenedione, dihydrotestosterone to 5-alpha-androstane-3 beta,17 beta-diol, dehydroepiandrosterone to androstenedione and 5-alpha-androstan-3 beta,17 beta-diol to 5-alpha-dihydrotestosterone.
Gene Name:: HSD3B1
Uniprot ID:: P14060
Molecular weight:: 42251.25
