Anti-Peroxiredoxin 1 (PRDX1)

Human Peroxiredoxin1 (Prx-1, also known as Thioredoxin peroxidase 2) is a 22kD antioxidant enzyme that belongs to the typical 2-Cys class of the THP/ahpC family of proteins. The molecule is 199aa in length and has two catalytic cysteines, one at Cys52 and a second at Cys173. Prx-1 is an obligate homodimer. In its inactive state, Prx-1 is apparently noncovalently associated. Upon peroxide binding to Cys52 of subunit 1, the Cys173 of subunit 2 interacts with Cys52 of subunit 1 to complete the antioxidation, generating a disulfide bond between Cys52 and Cys173. Subsequent reduction restores the subunits to the basal state. There are apparently two additional isoforms, one shows a premature truncation after aa171, while the second shows a deletion of aa21-121. Human Prx-1 is 96% aa identical to mouse Prx-1.
