Aug 11, 2021 · The expression of soluble TrxA 6 × His -AnCra1 was highest when induced at 19 °C, therefore, temperature had the greatest effect on the expression of soluble tagged fusion protein. To purify the TrxA, 6 × His -AnCra1 fusion protein, the extract soluble cell lysate was loaded onto a Ni–NTA-affinity column and eluted. Since both these genes are annotated as trxA in the F. tularensis LVS genome, we designated FTL_0611 as trxA1 and FTL_1224 as trxA2. The TrxA1 exhibits structural and regulatory features characteristic of bacterial thioredoxins, including the CxxC motif, but lacks two additional N-terminal CxxC motifs present in Trx2 of E. coli.
