Compound as reactive (7)
testosterone + NADP+ ← androst-4-ene-3,17-dione + NADPH + H+
androst-4-ene-3,17-dione + NADPH + H+ + oxygen → H2O + testololactone + NADP+
androst-4-ene-3,17-dione + a reduced electron donor + oxygen → an oxidized electron donor + H2O + testololactone
2 a reduced ferredoxin [iron-sulfur] cluster + 2 H+ + androst-4-ene-3,17-dione + oxygen → 2 an oxidized ferredoxin [iron-sulfur] cluster + 1α-hydroxyandrost-4-ene-3,17-dione + H2O
5-β-androstane-3,17-dione + NADP+ ← androst-4-ene-3,17-dione + NADPH + H+
an oxidized electron donor + androst-4-ene-3,17-dione → androsta-1,4-diene-3,17-dione + a reduced electron donor
androst-4-ene-3,17-dione + oxygen → H2O + 19-hydroxyandrost-4-ene-3,17-dione
Compound as product (6)
testosterone + NAD(P)+ → androst-4-ene-3,17-dione + NAD(P)H + H+
an oxidized electron donor + 5α-androstane-3,17-dione → androst-4-ene-3,17-dione + a reduced electron donor
5-androstene-3,17-dione → androst-4-ene-3,17-dione
17-hydroxy-3-oxo-4-pregnane-20-carboxyl-CoA → androst-4-ene-3,17-dione + propanoyl-CoA
17-α-hydroxyprogesterone + NADPH + oxygen → androst-4-ene-3,17-dione + acetate + H2O + NADP+
17-α-hydroxyprogesterone → androst-4-ene-3,17-dione + acetaldehyde
Reversible reaction (1)
testosterone + NAD+ ↔ androst-4-ene-3,17-dione + NADH
