When thioredoxin is expressed from plasmid vectors in E. coli, it can accumu-late to 40% of the …H. pylori also contains two genes that encode Trx, trxA and trxC. TrxA expression in H. pylori is induced by stress agents, and it is the electron donor for antioxidant enzymes [24, 30]. TrxC acts as a chaperone and transforms denatured arginase into its active form . There are three thioredoxin in the E. piscicida genome, TrxA, TrxC, …The resulting TrxA/ssTorA chimeras were expressed at a level comparable to TrxA chimeras carrying N-terminal ssTorA (cf. Fig. 4a, lane 4, c, lane 1). Furthermore, very similar to the N-terminal ssTorA (Fig. 4a, lane 5), the C-terminal fusion appeared to render TrxA mostly insoluble using an IB sedimentation assay (Fig. 4c, lane 2).
