-   Contributes to oxidative stress resistance by reducing cysteine-sulfinic acid formed under exposure to oxidants in the peroxiredoxins [PMID: 15448164].
-   Reduction of cysteine sulfinic acid by sulfiredoxin is specific to 2-cys peroxiredoxins. May catalyze the reduction in a multi-step process by acting both as a specific phosphotransferase and a thioltransferase [PMID: 15590625].
-   Sufiredoxins (Srx) repair the inactivated forms of typical two-Cys peroxiredoxins (Prx) implicated in hydrogen peroxide-mediated cell signaling. The reduction of the cysteine sulfinic acid moiety within the active site of the Prx by Srx involves novel sulfur chemistry and the use of ATP and Mg(2+) [PMID: 15952770].
