Metabolite Identification

Common Name

17alpha,21-Dihydroxypregnenolone

Description

17alpha,21-Dihydroxypregnenolone is an intermediate in the human fetus at midpregnancy that is converted into cortisol (PMID: 4231965 ). It has also been found as an intermediate in alternative pathways in human adrenal steroidogenesis that take place under in vitro conditions. In normal adrenal slices from patients with hypernephroid kidney carcinomas these pathways bypass cholesterol, pregnenolone, and progesterone, and proceed to 21-hydroxypregnenolone (PMID: 6247575 ). 17alpha,21-Dihydroxypregnenolone is an intermediate in C21-Steroid hormone metabolism. 17alpha,21-Dihydroxypregnenolone is the 5th to last step in the synthesis of Cortol and is converted from 17alpha-Hydroxypregnenolone via the enzyme cytochrome P450 (EC 1.14.99.10). It is then converted to 11beta,17alpha,21-Trihydroxypregnenolone via the enzyme cytochrome P450 (EC 1.14.15.4).

Enzymes

Enzyme Details

1. Cytochrome P450 11B1, mitochondrial

General function:: Involved in monooxygenase activity
Specific function:: Has steroid 11-beta-hydroxylase activity. In addition to this activity, the 18 or 19-hydroxylation of steroids and the aromatization of androstendione to estrone have also been ascribed to cytochrome P450 XIB.
Gene Name:: CYP11B1
Uniprot ID:: P15538
Molecular weight:: 57572.44

Reactions

17alpha,21-Dihydroxypregnenolone + Reduced ferredoxin + Oxygen → 11b,17a,21-Trihydroxypreg-nenolone + Oxidized ferredoxin + Water	details

Enzyme Details

2. 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

Reactions

Cortexolone + Hydrogen Ion + NADH → 17alpha,21-Dihydroxypregnenolone + NAD	details
