Enzymes

Enzyme Details
1. Aldo-keto reductase family 1 member C4
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,21-Dihydroxy-5b-pregnane-11,20-dione + NAD → 21-Hydroxy-5b-pregnane-3,11,20-trione + NADH + Hydrogen Iondetails
3a,21-Dihydroxy-5b-pregnane-11,20-dione + NADP → 21-Hydroxy-5b-pregnane-3,11,20-trione + NADPH + Hydrogen Iondetails
Enzyme Details
2. Corticosteroid 11-beta-dehydrogenase isozyme 2
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the conversion of cortisol to the inactive metabolite cortisone. Modulates intracellular glucocorticoid levels, thus protecting the nonselective mineralocorticoid receptor from occupation by glucocorticoids.
Gene Name:
HSD11B2
Uniprot ID:
P80365
Molecular weight:
44126.06
Enzyme Details
3. Corticosteroid 11-beta-dehydrogenase isozyme 1
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes reversibly the conversion of cortisol to the inactive metabolite cortisone. Catalyzes reversibly the conversion of 7-ketocholesterol to 7-beta-hydroxycholesterol. In intact cells, the reaction runs only in one direction, from 7-ketocholesterol to 7-beta-hydroxycholesterol (By similarity).
