Abstract excerpt
The Salmonella typhimurium PhoP-PhoQ two-component regulatory system controls the expression of several genes, some of which are necessary for virulence. During a screening for PhoP-regulated genes, we identified the phoPQ operon as a PhoP-activated locus. beta-Galactosidase activity originating from phoPQ-lac transcriptional fusions required the presence of both the transcriptional regulator PhoP and its cognate...
