In order to understand its pathogenic mechanism, additional new virulence factors need to be identified. The bacterial thioredoxin system is a major disulfide reductase system, but its function is largely unknown in E. piscicida.In this study, we investigated …

Since the trxA gene is located downstream of groEL and co-organized as an operon, it is possible that the control of trxA expression depends not only on the trxA-self promoter but also on the CtsR regulation system. Therefore, we examined transcriptional profiles under the treatment of heat shock and disulfide stress by Northern blot.

Jun 28, 2017 · Abstract. Microbes employ the thioredoxin system to defend against oxidative stress and ensure correct disulfide bonding to maintain protein function. Listeria monocytogenes has been shown to encode a putative thioredoxin, TrxA, but its biological roles and underlying mechanisms remain unknown. 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. A number of unique structural and regulatory features distinguish the Trx2 subfamily from the much larger TrxA family. The Trx2 subfamily has an additional N-terminal domain of ± 30 residues ...
