Thioredoxin reductase is essential for protection of Neisseria gonorrhoeae against killing by nitric oxide and for bacterial growth during interaction with cervical epithelial cells.

Abstract excerpt

In Neisseria gonorrhoeae, the MerR family transcription factor NmlR activates 3 operons in response to disulfide stress. In the present study, we show that trxB, a monocistronic operon under the control of NmlR, encodes a functional thioredoxin reductase. It is shown that neisserial TrxB has biochemical properties similar to those of its homologue from Escherichia coli. Analysis of a trxB mutant of N. gonorrhoeae...
