Cholest-4-en-3-one 26-monooxygenase ( EC 1.14.13.141, CYP125, CYP125A1, cholest-4-en-3-one 27-monooxygenase) is an enzyme with systematic name cholest-4-en-3-one,NADH:oxygen oxidoreductase (26-hydroxylating). [1] [2] [3] [4] This enzyme catalyses the following chemical reaction

cholest-4-en-3-one + NADH + H+ + O2 26-hydroxycholest-4-en-3-one + NAD+ + H2O

Cholest-4-en-3-one 26-monooxygenase is a heme thiolate (P450) enzyme.
