Expression of CtrA-dependent promoters in wild-type and YB3558 strains. β-galactosidase assays were performed on exponentially growing cultures as described in the Methods. CtrA-dependent promoters of essential cell process genes show little-to-no change between wild-type and YB3558, while the pilA promoter shows a drastic difference in expression between the strains.
