Eukaryotic 2-Cys peroxiredoxins (Prx) are abundant antioxidant enzymes whose thioredoxin peroxidase activity plays an important role in protecting against oxidative stress, aging, and cancer. Paradoxically, this thioredoxin peroxidase activity is highly sensitive to inactivation by peroxide-induced Prx hyperoxidation. However, any
