Enzymes

Enzyme Details
1. 3-oxo-5-beta-steroid 4-dehydrogenase
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.
Gene Name:
AKR1D1
Uniprot ID:
P51857
Molecular weight:
32889.38
Reactions
7a,12a-Dihydroxy-5b-cholestan-3-one + NADP → 7a,12a-Dihydroxy-cholestene-3-one + NADPH + Hydrogen Iondetails
Enzyme Details
2. 3-oxo-5-alpha-steroid 4-dehydrogenase 2
General function:
Involved in 3-oxo-5-alpha-steroid 4-dehydrogenase activity
Specific function:
Converts testosterone (T) into 5-alpha-dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.

4. 7-alpha-hydroxycholest-4-en-3-one 12-alpha-hydroxylase
General function:
Involved in monooxygenase activity
Specific function:
Involved in bile acid synthesis and is responsible for the conversion of 7 alpha-hydroxy-4-cholesten-3-one into 7 alpha, 12 alpha-dihydroxy-4-cholesten-3-one. Responsible for the balance between formation of cholic acid and chenodeoxycholic acid. Has a rather broad substrate specificity including a number of 7-alpha-hydroxylated C27 steroids.
