pmrA(Con) confers pmrHFIJKL-dependent EGTA and polymyxin resistance on msbB Salmonella by decorating lipid A with phosphoethanolamine.

Journal of bacteriology - 1 Jul 2007

Abstract excerpt

Mutations in pmrA were recombined into Salmonella strain ATCC 14028 msbB to determine if pmrA-regulated modifications of lipopolysaccharide could suppress msbB growth defects. A mutation that functions to constitutively activate pmrA [pmrA(Con)] suppresses msbB growth defects on EGTA-containing media. Lipid A structural analysis showed that Salmonella msbB pmrA(Con) strains, compared to Salmonella msbB strains,...
