However, rapid folding of TrxA after translation prevents it from crossing the plasma membrane (Huber et al. 2005).

The Escherichia coli K-12 trxA gene, the gene encoding thioredoxin, has been cloned and sequenced. The DNA sequence includes 280 base pairs upstream and 46 base pairs downstream of the coding region.

Although TrxC is a thioredoxin secondary to TrxA in bacteria, deletion of trxC clearly suppressed the reduction in the transcript at a longer time point , implying that TrxC functions at least as an SqrR-induced polysulfide homeostasis system. Thus, although TrxA and TrxC play essentially redundant physiological roles, each also exerts specific ...The TrxA protein, which is about 11 kDa in size, can be used with larger target proteins, but it is most suitable for enhancing the solubility of proteins that contain disulfide bonds [23].
