The trxA expression is not affected by inducer removal in the WT, whereas the amount of trxA decreased to undetectable levels in STXA2 relative to the WT (Figure 1, C and D). Western blot analysis showed that TrxA protein level was about 10% in STXA2 of that in the WT in the presence of inducer ( Figure 1, E and F ).To contrast, however, solubility of Mesorhizobium loti carbonic anhydrase was enhanced using the J23100 constitutive promoter in combination with a N-terminal TrxA fusion on a pSUM backbone and co-expression of GroEL/ES; this improvement was in comparison with a similar experimental design with pET28a and pET32a using an …Two thioredoxins have been described in Escherichia coli, TrxA and Trx2. Both thioredoxins are capable of reducing disulfide bonds using a conserved pair of cysteine residues present in a WCGPC motif.

In contrast, aptamer G1 did not show appreciable binding to its target GST protein in solution. These results again support the idea that aptamer affinity is often greatly influenced by the environmental factors and aptamers tend to perform the best in ...

Free TrxA was used in the serum dilution fluid to block any non-specific antibodies which might bind to TrxA (Fig. 5 A). A bead coupled with TrxA alone was used to monitor the presence and degree of remaining TrxA antibodies. Likewise, antibodies reactive with E. coli could be blocked by including E. coli lysate during the preincubation …

sion proteins, TrxA has been shown to aid in the crystallization of proteins. Though in most in-stances TrxA must be removed prior to structural characterization, TrxA when joined with the linker sequence GSAM aided crystallization of the U2AF homology motif domain of splicing factor Puf60 [41].
