Abstract excerpt
The defensin sensitivities of Salmonella typhimurium strains with mutations in the phoP/phoQ two-component virulence regulon were tested by using purified defensins NP-1 and NP-2. Strains with mutations in either gene of the regulatory pair (phoP [transcriptional activator] or phoQ [membrane sensor kinase]) had increased sensitivities to defensin. The predicted periplasmic domain of the PhoQ protein contained a...
