ID 1.1.3.6 DE cholesterol oxidase. AN cholesterol-O2 oxidoreductase. CA cholesterol + O2 = cholest-5-en-3-one + H2O2. CC -!- Cholesterol oxidases are secreted bacterial bifunctional enzymes that CC catalyze the first two steps in the degradation of cholesterol. CC -!- The enzyme catalyzes the oxidation of the 3beta-hydroxyl group to a CC keto group, and the isomerization of the double bond in the oxidized CC steroid ring system from the Delta(5) position to the Delta(6) CC position (cf. EC 5.3.3.1). DR P22637, CHOD_BREST ; P9WMV8, CHOD_MYCTO ; P9WMV9, CHOD_MYCTU ; DR P12676, CHOD_STRS0 ; //
