soxR

Accession ARO:3000836
DefinitionSoxR is a sensory protein that upregulates soxS expression in the presence of redox-cycling drugs. This stress response leads to the expression many multidrug efflux pumps. In Pseudomonas aeruginosa, which lacks SoxS, SoxR is able to directly upregulate the expression of the MexGHI-OpmD efflux pump.
