WebNov 25, 2024 · In the last two decades, redox proteomics has emerged as a powerful strategy to offer a global landscape of the cysteine-mediated redox network in biological systems 13. WebAnnexin A2 possesses a reactive cysteine residue (Cys-8) that is readily oxidized by H2O2 and subsequently reduced by the thioredoxin system, thereby enabling annexin A2 to participate in multiple redox cycles. Thus, a single molecule of annexin A2 can inactivate several molecules of H2O2.
