Consistent with OmpR have recently shown that OmpR regulates the acid induction of the ssrAB two-component signal transduction system located within the Spi2 pathogenicity island .
Consistent with OmpR have recently shown that OmpR regulates the acid induction of the ssrAB two-component signal transduction system located within the Spi2 pathogenicity island .
OmpR activates SPI-2 genes by binding to the promoter of the ssrAB operon to induce expression of SsrB proteins .
OmpR activates SPI-2 genes by binding to the promoter of the ssrAB operon to induce expression of SsrA proteins .
Further , as mentioned previously , OmpR is a direct transcriptional activator of ssrAB .
