Like marRAB , acrAB are positively regulated by MarA .
In S. enterica the global regu-2 MarA regulate the acrAB operon by binding to mar/sox boxes .
Expression of acrAB-tolC is regulated by the global regulator , MarA .
Other regulators of MarA did not contrib-ute to acrAB induction by indole in Salmonella .
In E. coli , the transcription of acrAB is controlled by the homologous proteins MarA .
In particular , the expression of acrAB is regulated by MarA .
For example , acrAB transcription in Salmonella is controlled by MarA .
At a global level , acrAB expression is regulated by MarA .
