>cd02971 PRX_family Peroxiredoxin (PRX) family; composed of the different classes of PRXs including many proteins originally known as bacterioferritin comigratory proteins (BCP), based on their electrophoretic mobility before their function was identified. PRXs are thiol-specific antioxidant (TSA) proteins also known as TRX peroxidases and alkyl hydroperoxide reductase C22 (AhpC) proteins. They confer a protective antioxidant role in cells through their peroxidase activity in which hydrogen peroxide, peroxynitrate, and organic hydroperoxides are reduced and detoxified using reducing equivalents derived from either TRX, glutathione, trypanothione and AhpF. They are distinct from other peroxidases in that they have no cofactors such as metals or prosthetic groups. The first step of catalysis, common to all PRXs, is the nucleophilic attack by the catalytic cysteine (also known as the peroxidatic cysteine) on the peroxide leading to cleavage of the oxygen-oxygen bond and the formation of a
