that OmpR binds directly to ssrB regulatory regions to affect their expression
Previous results from gene fusions suggest that regulation of ssrB by OmpR is distinct .
Previous results from gene fusions suggest that regulation of ssrB by OmpR is uncoupled .

Other examples of genes include ssrB known regulators of SPI-2 previously reported to be influenced by OmpR Figure 7 .

previous work in Salmonella has shown that phosphorylated OmpR can bind to either ssrB within SPI-2
In low-osmolarity conditions , OmpR and/or OmpR-P -LRB- phosphorylayted OmpR present in low levels -RRB- can bind to the upstream regions of ssrB genes .
Under low osmolality , the ssrB genes are transcriptionally activated by the binding of OmpR ~ P to their promoters whose levels are in turn .
Under acidic pH , the ssrB genes are transcriptionally activated by the binding of OmpR ~ P to their promoters whose levels are in turn .
The OmpR protein regulates the transcription of the ssrB genes , partly by acting there as a conventional TF .
The OmpR protein regulates the transcription of the ssrB genes , partly by acting there by acting as an anti-repressor .
For example , OmpR promotes SPI-2 expression by directly binding to both ssrB promoters .
