Disulfide daim ntawv cog lus tsim thiab isomerization yog catalyzed cov txheej txheem hauv ob qho tib si prokaryotes thiab eukaryotic kab mob, thiab cov enzymes lub luag haujlwm hu ua "disulfide bond (Dsb) enzymes" rau lawv lub peev xwm cuam tshuam. tsim thiab isomerization ntawm disulfide bonds.

Cov txuas hniav disulfide nyob qhov twg?

Disulfide daim ntawv cog lus feem ntau tshwm sim hauv lub endoplasmic reticulum los ntawm oxidation. Yog li no disulfide bonds feem ntau pom muaj nyob rau hauv extracellular, secreted thiab periplasmic proteins, txawm hais tias lawv muaj peev xwm kuj tsim nyob rau hauv cytoplasmic proteins nyob rau hauv tej yam kev mob ntawm oxidative kev nyuaj siab.
