Strains deficient in SsrA-mediated proteolysis are only moderately sensitive to cell envelope stress. Uncomplemented LacZ− deletion mutants of ssrA (GSO294) (n = 4) as well as deletion mutants of ssrA-deficient mutants complemented with either a wild-type allele of ssrA [ssrA+ (GSO301)] (n = 6) or an ochre codon mutant [ssrAO (GSO302)] (n = 5) were evaluated against LacZ+ wild-type MG1655 cells. A deletion mutant of clpP (GSO303) was also evaluated against LacZ− (NM601) cells (n = 3). A CI was calculated for each experiment. The error bars represent 1 standard deviation from the mean.
