Cys thiol

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. WebOn the other hand, the sequential approach requires the use of orthogonal protecting groups for Cys side-chain thiols [54, 56]. In this case, each disulfide bond is formed sequentially from pairs ...
