アプリケーション
Cholesterol oxidase has been used in a study to improve treatment of oxysterol-mediated cytotoxicity. Cholesterol oxidase has also been used in a study that determined that cholesterol depletion impairs coupling between channel opening and vesicle release by allowing voltage-gated calcium channels to move further from release sites.
Cholesterol oxidase has been used in a study to improve treatment of oxysterol-mediated cytotoxicity. Cholesterol oxidase has also been used in a study that evaluated the effects of cholesterol depletion. This study reported that cholesterol depletion impairs the coupling between channel opening and vesicle release. Additionally, cholesterol oxidase is used to determine serum cholesterol levels. The enzyme also finds application in the microanalysis of steroids in food samples. It has also been used for distinguishing 3-ketosteroids from 3β-hydroxysteroids. Transgenic plants expressing cholesterol oxidase have been investigated in the fight against the cotton boll weevil. CHOD has also been used as a molecular probe to elucidate cellular membrane structures.
生物化学的／生理学的作用
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. The pH optimum of the enzyme is 7.0 to 7.5 and temperature optimum is 50 °C. The pH stability is 5.7-7.8. Hg2+, Ag+, and ionic detergents inhibit the enzyme activity. Molecular mass of the enzyme is 62 kDa. Pathogenic bacteria require CHOD to infect a host′s macrophage.

Pathogens hijack host endocytic pathways to force their own entry into eukaryotic target cells. Many bacteria either exploit receptor-mediated zippering or inject virulence proteins directly to trigger membrane reorganisation and cytoskeletal rearrangements. By contrast, extracellular C. trachomatis elementary bodies (EBs)
