I-Cholesterol oxidase(COD/CHOD)
Inkcazo
I-Cholesterol oxidase (CHOD) yenza inyathelo lokuqala kwi-cholesterol catabolism.Ezinye iibhaktheriya ezingekho kwi-pathogenic, ezifana ne-Streptomyces ziyakwazi ukusebenzisa i-cholesterol njengomthombo wekhabhoni.Iibhaktheriya ze-Pathogenic, ezifana ne-Rhodococcus equi, zifuna i-CHOD ukuba ihlasele i-macrophage yomninimzi.I-CHOD iyasebenza kabini.I-cholest-5-en-3-enye i-isomerized ukuya kwi-cholest-4-en3-one.I-reaction ye-isomerization inokuguqulwa ngokuyinxenye.Umsebenzi we-CHOD uxhomekeke kwiipropati ezibonakalayo ze-membrane apho i-substrate iboshiwe.
I-CHOD isetyenziselwa ukumisela i-cholesterol ye-serum.Yesibini i-enzyme esetyenziswa kakhulu kwizicelo zokuxilonga emva kwe-glucose oxidase.I-CHOD iphinda ifumane isicelo kwi-microanalysis ye-steroids kwiisampuli zokutya kunye nokuhlukanisa i-3-ketosteroids ukusuka kwi-3b-hydroxysteroids.Izityalo zeTransgenic ezibonisa i-cholesterol oxidase ziphandwa ekulweni ne-cotton boll weevil.I-Cholesterol oxidase nayo isetyenziswe njengeprobe ye-molecular ukucacisa izakhiwo ze-cellular membrane.
