Figure 6:

Comparison of force vs. time of linker-stretched hairpin structure and BamA β-barrel with EspP passenger domain. The black line shows the average force vs. time of the secretion of linker stretched hairpin structure from three replicas and the green line shows that of the BamA β-barrel with the EspP passenger domain from three replicas. Both lines are running average of the raw data taken over 10 ns. The error bars for linker-stretched hairpin structure and BamA β-barrel with EspP passenger domain are shown in blue and red, respectively.
