Effect of the protease activity of Prc on serum survival of E. coli. (A) Survival of WT-RS218 preincubated with or without the inhibitor peptide GRGYALAA in NHS. (B) Survival of WT-RS218 preincubated with or without the inhibitor peptide in HI-NHS. For panels A and B, the results of serum survival are presented as the survival rates of the original inoculums. (C) Survival of Δprc-RS218 strains that were complemented with plasmid pTR147 or pTR163 after incubation in 60% NHS for 15 min. The results of serum survival are presented as relative survival rates compared to the survival rates of WT-RS218. All of the data shown are representative of three independent experiments performed in triplicate. The results are shown as the means ± standard deviations. *, P values of <0.05; ***, P values of <0.001.
