Figure 2.
Doubling time of E. coli ΔssrA or ΔsmpB mutants expressing SmpBHp WT, SsrAHp WT or mutants. Doubling times were calculated for E. coli strains expressing SmpBHp, SsrAHp and different mutant versions of SsrAHp from plasmids. Doubling times (g values) correspond to the mean generation time. As a control, growth complementation of the E. coli ΔssrA with Ec-ssrA is presented. Empty vector corresponds to a vector without insert.
