WebJul 1, 2015 · Cys is incorporated into protein as the thiol (RSH) form, with apparently no exception. Thiols are oxidized to sulfenic acids (RSO −) intermediate to formation of disulfides (RSSR) and higher oxidation states (e.g., RSO 2− ). WebProtein Cys thiols (–SH) are intrinsically reactive and susceptible to oxidation by hydrogen peroxide (H 2 O 2), the most stable among the reactive oxygen species (ROS).The reaction between thiols and H 2 O 2 initially forms sulfenic acid (R-SOH; S-sulfenylation), a transient OxiPTM that either can be reversed or can serve as a gateway toward other OxiPTM types. WebDec 23, 2024 · The proteomic compendium of active mitochondrial thiol switches that we have generated demonstrates that a large number of proteinaceous Cys thiols cannot only be reduced in vitro (33–37), but are operated in the intact mitochondrion linked to metabolic activity.
