General description
Type II cholesterol oxidase containing FAD cofactor covalently linked to the enzyme.
Application
Cholesterol oxidase has been used in a study to demonstrate that microheterogeneity in hydrophobic-hydrophilic block copolymer systems can be exploited for immobilizing enzymes and to carry out enzymatic reactions. Cholesterol oxidase has also been used in a study that concluded that amphipaths that activate cholesterol might be useful in treating NPC disease.
Cholesterol oxidase is used to determine serum cholesterol.[1][2] The enzyme also finds application in the microanalysis of steroids in food samples and in distinguishing 3-ketosteroids from 3β-hydroxysteroids.[3] Transgenic plants expressing cholesterol oxidase are being investigated in the fight against the cotton boll weevil.[4] CHOD has also been used as a molecular probe to elucidate cellular membrane structures.[5][6]
Biochem/physiol Actions
Cholesterol oxidase (CHOD) is a monomeric flavoprotein containing FAD that catalyzes the first step in cholesterol catabolism. This bifunctional enzyme oxidizes cholesterol to cholest-5-en-3-one in an FAD-requiring step, which is then isomerized to cholest-4-en-3-one with the release of H2O2.[7]
Physical form
Supplied as a lyophilzed powder containing sucrose
Other Notes
One unit will convert 1.0 μmole of cholesterol to 4-cholesten-3-one per min at pH 7.5 at 25 °C. Note: 4-cholesten-3-one may undergo isomerization.
