The peroxiredoxins (Prx) are ubiquitous thiol peroxidases, which play a central role in the physiology of hydrogen peroxide. A subclass of Prx called "typical 2-Cys-Prx" has a unique property to hyperoxidize the catalytic Cys into the sulfinic acid form, which acts as a regulation mechanism of their functions, as peroxidase, peroxide sensor or protein chaperone. The reduction of the overoxidized form is catalyzed by sulfiredoxin (Srx), an ATP-dependent sulfinyl reductase whose catalytic constant is about 1-2 min-1, a low value that must be correlated to the role of Srx in redox regulation. The aim of this study was to analyze the enzymology of the regulation of the Prx/Srx system at three diffrents points of control: the hyper-oxidation pro...
