Abstract excerpt
The alternative sigma factor sigma(E) is critical for envelope stress response and plays a role in pathogenicity of a variety of different bacteria. We previously identified several critical nucleotides in the Salmonella enterica serovar Typhimurium (S. Typhimurium) sigma(E)-dependent rpoEp3 promoter that corresponded to the most conserved nucleotides in the sigma(E) consensus sequence of the -10 and -35 promoter...
