Metabolite Identification
Common Name11b,17a,21-Trihydroxypreg-nenolone
Description11beta,17alpha,21-Trihydroxypregnenolone is an intermediate in C21-Steroid hormone metabolism. 11beta,17alpha,21-Trihydroxypregnenolone is the 4th to last step in the synthesis of Cortol and is converted from 17alpha,21-Dihydroxypregnenolone via the enzyme cytochrome P450 (EC:1.14.15.4). It is then converted to Cortisol via the enzyme 3beta-hydroxy-delta5-steroid dehydrogenase (EC 1.1.1.145) and the enzyme steroid delta-isomerase (EC 5.3.3.1).

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 + Waterdetails
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.
