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 thanBy co-expressing GroELS in 21-GRC and 32-GRC, the soluble form of RcHemA or TrxA-RcHemA (represented by S) was increased (Fig. 2b). Additionally, when TrxA was fused on the upstream of RcHemA, the partner GroELS was very helpful in protein folding, suggesting that 32-GRC is the best strain for obtaining more functional proteins.Mehr 6, 1391 AP ...
