Our laboratory is interested in signal transduction and the regulation of gene expression in prokaryotes. In particular, we are studying the two-component regulatory system EnvZ/OmpR that regulates the expression of outer membrane proteins as well as many other genes. OmpR is involved in regulating the expression of virulence genes in many pathogens. Our present work focuses on how OmpR activates genes required for systemic infection (located on Salmonella pathogenicity island 2) in Salmonella enterica.
