As OmpR also controls the expression of the acid-induced virulence operon ssrAB , acid shock induction of ompR was examined to gain insight into how Salmonella links virulence with survival at extreme acid-pH .
In this paper , we examine the details of ompR induction by the potential roles of alternative OmpR phosphodonors in acid tolerance .
OmpR _ serving as an activator of ompR transcription during P1 , transcript
OmpR _ serving as an activator of ompR transcription during the P2
OmpR _ serving as an activator of ompR transcription during acid shock
A radiolabelled ompR promoter DNA fragment were incubated with increasing quantities of OmpR -LRB- as indicated -RRB- for 2 h at room temperature .
A. Western blot analysis of OmpR was used to examine the effect of hns on the acid shock induction of ompR .

CadC interacts directly with OmpR Since S. enterica serovar Typhimurium OmpR response re-gulator was shown to induce its own synthesis by binding to its promoter ( Bang et al. , 2002 ) , we hypothesized that CadC could mediate the repression of ompR gene expression by direct interaction with OmpR , sterically hindering binding of OmpR to its own promoter or RNA polymerase .
