Compound as reactive (1)
3'-phosphoadenylyl-sulfate + 3-β-hydroxyandrost-5-en-17-one → adenosine 3',5'-bisphosphate + 3-β-hydroxyandrost-5-en-17-one 3-sulfate + H+
Compound as product (2)
2 NADPH + 2 H+ + 17-α-hydroxypregnenolone + oxygen → 2 H2O + 2 NADP+ + acetaldehyde + 3-β-hydroxyandrost-5-en-17-one
H2O + 3-β-hydroxyandrost-5-en-17-one 3-sulfate → 3 H+ + 3-β-hydroxyandrost-5-en-17-one + sulfate
Reversible reaction (3)
NAD+ + 3-β-hydroxyandrost-5-en-17-one ↔ 5-androstene-3,17-dione + NADH + H+
androsterone + NADP+ ↔ NADPH + 3-β-hydroxyandrost-5-en-17-one + H+
an oxidized electron donor + androsterone ↔ a reduced electron donor + 3-β-hydroxyandrost-5-en-17-one
