WebApr 1, 2024 · Cys thiol-based OxiPTMs and feedback regulation The regulatory functions of ROS/RNS/RSS are largely exerted by through oxidative post-translational modifications (OxiPTMs) of proteins [ 4, 8, 9, 11 ]. In plants, H 2 O 2, NO, and H 2 S are the most studied ROS/RNS/RSS. WebJan 7, 2014 · The deprotonated Cys provides a strong thiolate “push” that enables heterolytic O—O bond cleavage by P450 enzymes ( 1 ). Protonation of the native thiolate ligand to a neutral thiol has been suggested as a mechanism of P450 deactivation yielding the infamous P420 species ( 11 ).

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.
