Common Name11b,21-Dihydroxy-5b-pregnane-3,20-dione
Description11beta,21-Dihydroxy-5beta-pregnane-3,20-dione is an intermediate in C21-Steroid hormone metabolism. 11beta,21-Dihydroxy-5beta-pregnane-3,20-dione is the 3rd to last step in the synthesis of 3alpha,20alpha,21-Trihydroxy-5beta-pregnane-11-one and is converted from Corticosterone via the enzyme 3-oxo-5beta-steroid 4-dehydrogenase (EC 1.3.99.6). It is then converted to Tetrahydrocorticosterone via the enzyme 3-alpha-hydroxysteroid dehydrogenase (EC 1.1.1.50).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20-alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route.
Gene Name:
AKR1C4
Uniprot ID:
P17516
Molecular weight:
37094.57
Reactions
Tetrahydrocorticosterone + NAD → 11b,21-Dihydroxy-5b-pregnane-3,20-dione + NADH + Hydrogen Iondetails
Tetrahydrocorticosterone + NADP → 11b,21-Dihydroxy-5b-pregnane-3,20-dione + NADPH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Efficiently catalyzes the reduction of progesterone, androstenedione, 17-alpha-hydroxyprogesterone and testosterone to 5-beta-reduced metabolites. The bile acid intermediates 7-alpha,12-alpha-dihydroxy-4-cholesten-3-one and 7-alpha-hydroxy-4-cholesten-3-one can also act as substrates.
