Common Name11b,21-Dihydroxy-3,20-oxo-5b-pregnan-18-al
Description11beta,21-Dihydroxy-3,20-oxo-5beta-pregnan-18-al is an intermediate in C21-Steroid hormone metabolism. 11beta,21-Dihydroxy-3,20-oxo-5beta-pregnan-18-al is converted from Aldosterone via the enzyme 3-oxo-5beta-steroid 4-dehydrogenase (EC:1.3.99.6). It is then converted to 3alpha,11beta,21-Trihydroxy-20-oxo-5beta-pregnan-18-al 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
3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al + NAD → 11b,21-Dihydroxy-3,20-oxo-5b-pregnan-18-al + NADH + Hydrogen Iondetails
3a,11b,21-Trihydroxy-20-oxo-5b-pregnan-18-al + NADP → 11b,21-Dihydroxy-3,20-oxo-5b-pregnan-18-al + 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.
