cholesterol + O2 = cholest-5-en-3-one + H2O2 | bifunctional enzyme, catalyzes both the oxidation of DELTA5-ene-3beta hydroxysteroids with a trans A-B ring junction to the corresponding DELTA5-3-ketosteroid with the reduction of oxygen to hydrogen peroxide, and the isomerization to the DELTA4-3-ketosteroid | Nocardia erythropolis |
