Like marRAB , acrAB are positively regulated by Rob .
While Rob appears to be an important positive regulator of acrAB in E. coli , we present data .
Rob has been demonstrated to directly regulate transcription of acrAB in E. coli .
Other regulators of Rob did not contrib-ute to acrAB induction by indole in Salmonella .
In E. coli , the transcription of acrAB is controlled by Rob .
the Rob protein _ involved in regulation of acrAB in E. coli
In particular , the expression of acrAB is regulated by Rob .
a high activity state _ allowing the activation of acrAB .18 Such a mechanism would be reminiscent of the binding of bile to the Rob protein 34
the Rob protein 34 _ involved in the regulation of acrAB in E. coli
For example , acrAB transcription in Salmonella is controlled by Rob .
