ENZYME entry: EC 1.1.3.6

Accepted Name
Cholesterol oxidase.
Alternative Name(s)
Cholesterol-O(2) oxidoreductase.
Reaction catalysed
Cholesterol + O(2) <=> cholest-5-en-3-one + H(2)O(2)
Cofactor(s)
FAD.
Comment(s)
  • Cholesterol oxidases are secreted bacterial bifunctional enzymes that catalyze the first two steps in the degradation of cholesterol.
  • The enzyme catalyzes the oxidation of the 3-beta-hydroxyl group to a keto group, and the isomerization of the double bond in the oxidized steroid ring system from the Delta(5) position to the Delta(6) position (cf. EC 5.3.3.1).
