ID 1.1.3.6 DE Cholesterol oxidase. AN Cholesterol-O(2) oxidoreductase. CA Cholesterol + O(2) = cholest-5-en-3-one + H(2)O(2). CF FAD. 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 3-beta-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). PR PROSITE; PDOC00543; DR P22637, CHOD_BREST ; Q57307, CHOD_MYCTU ; P12676, CHOD_STRS0 ; //
