TrxA reduces oxidized substrate using two vicinal Cys residues in the active center, and the oxidized form of TrxA is reduced by TrxR using NADPH .

capsulatus the trxA gene of R. sphaeroides shows a strong response to diamide. It increases about sixfold after addition of t-BOOH and two- to threefold after exposure to paraquat or H 2 O 2 (Li et al. 2003b). Apparently, glutathione depletion (induced by t-BOOH) is a stronger stimulus for trxA expression in R. sphaeroides than
