Common Name17a,21-Dihydroxy-5b-pregnane-3,11,20-trione
Description17alpha,21-Dihydroxy-5beta-pregnane-3,11,20-trione is an intermediate in C21-Steroid hormone metabolism. 17alpha,21-Dihydroxy-5beta-pregnane-3,11,20-trione is the second to last step in the synthesis of Cortolone and is converted. from Cortisone via the enzyme Delta4-3-oxosteroid 5beta-reductase (EC 1.3.1.3). It is then converted to Urocortisone 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
Tetrahydrocortisone + NAD → 17a,21-Dihydroxy-5b-pregnane-3,11,20-trione + NADH + 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.
