The catalytic cycle of PrxIIF consists of three steps ( Figure 3 ): (1) the nucleophilic attack of the peroxide by the conserved peroxidatic Cys (Cys-S P H) that is oxidized to sulfenic acid (Cys-S P OH), (2) the formation of the disulfide by attack of the free thiol of the resolving Cys (Cys-S R H) to release water, and (3) the regeneration of the thiol form by mitochondrial Trx o, Grx and GSH as electron donors (Finkemeier et al., 2005
