Peroxiredoxin (Prx) is an antioxidant enzyme detoxifying reactive oxygen species and has a cysteine at their active site. Prx enzymes modulate various receptor signaling pathways and protect cells from oxidatively induced death. Prx I to IV have two conserved Cys residues corresponding to Cys51 and Cys172 of mammalian Prx I. The active site cysteine (Cys51) is oxidized to cysteine sulfenic acid (Cys51-SOH) when a peroxide is reduced. Because Cys51-SOH is unstable, it forms a disulfide with Cys172-SH which comes from other subunit of the homodimer. The disulfide is then reduced back to the Prx active thiol form by the thioredoxin-thioredoxin reductase system. However, the formation of the disulfide is a slow process. Thus under oxidative stress condition, the sulfenic intermediate (Cys51-SOH) can be easily overoxidized to cysteine sulfinic acid (Cys-SO2H) or cysteine sulfonic acid (Cys-SO3H) before it is able to form a disulfide. Recent studies suggest that overoxidized Prx can be reduced back to the active form during recovery after oxidative stress. Anti-Prx-SO3 antibody recognizes both sulfinic and sulfonic forms of Prx and detects overoxidized Prx enzymes in H2O2-treated cells with high sensitivity and specificity.
