The expression of rob is negatively regulated by MarA in response to sodium salicylate and paraquat , respectively .
rob is negatively regulated by MarA The transcript levels of rob in the DsoxS strains were repressed after treatment with NaOCl as in the wild type .
rob is negatively regulated by MarA The transcript levels of rob in the DmarA strains were repressed after treatment with NaOCl as in the wild type .
MarA bind the promoter region of rob To determine whether the repression was due to a direct interaction between MarA with the promoter of rob , we performed a bioinformatic analysis .
other studies _ performed in E. coli where rob was shown to be negatively regulated by both MarA by a direct interaction with its promoter region
EMSAs _ demonstrating that MarA bind to the promoter region of rob , indicating that the repression exerted by MarA is due to a direct interaction with the DNA
