Cholesterol oxidase(COD/CHOD)
Tlhaloso
Cholesterol oxidase (CHOD) e hlohlelletsa mohato oa pele oa k'holeseterole ea catabolism.Libaktheria tse ling tse se nang pathogenic, joalo ka Streptomyces, li khona ho sebelisa k'holeseterole joalo ka mohloli oa khabone.Libaktheria tsa pathogenic, tse kang Rhodococcus equi, li hloka hore CHOD e tšoaetse macrophage ea motho ea amohelang baeti.Cholest-5-en-3-one e isomerized ho cholest-4-en3-one. Boitšoaro ba isomerization bo ka fetoha ka mokhoa o itseng.Mosebetsi oa CHOD o itšetlehile ka thepa ea 'mele ea lera eo substrate e tlamisoang ho eona.
CHOD e sebelisoa ho khetholla serum cholesterol.Ke enzyme ea bobeli e sebelisoang haholo lits'ebetsong tsa tlhahlobo ka mor'a glucose oxidase.CHOD e boetse e fumana ts'ebetso ho microanalysis ea steroid ka lisampole tsa lijo le ho khetholla 3-ketosteroids ho tloha 3b-hydroxysteroids. Limela tsa Transgenic tse hlalosang k'holeseterole oxidase li ntse li batlisisoa ntoeng khahlanong le k'hothone ea boll weevil.Cholesterol oxidase le eona e 'nile ea sebelisoa e le probe ea limolek'hule ho hlakisa libopeho tsa lisele tsa cellular.

Cholesterol + O2 →△4-Cholesten-3-one + H2O2
