>cd03015 PRX_Typ2cys Peroxiredoxin (PRX) family, Typical 2-Cys PRX subfamily; PRXs are thiol-specific antioxidant (TSA) proteins, which confer a protective role in cells through its peroxidase activity by reducing hydrogen peroxide, peroxynitrite, and organic hydroperoxides. The functional unit of typical 2-cys PRX is a homodimer. A unique intermolecular redox-active disulfide center is utilized for its activity. Upon reaction with peroxides, its peroxidatic cysteine is oxidized into a sulfenic acid intermediate which is resolved by bonding with the resolving cysteine from the other subunit of the homodimer. This intermolecular disulfide bond is then reduced by thioredoxin, tryparedoxin or AhpF. Typical 2-cys PRXs, like 1-cys PRXs, form decamers which are stabilized by reduction of the active site cysteine. Typical 2-cys PRX interacts through beta strands at one edge of the monomer (B-type interface) to form the functional homodimer, and uses an A-type interface (similar to the dimeric
