Figure 6. CdiA-CT536 is not translocated via known toxin-import pathways.
Wild-type E. coli X90 and the indicated mutants were treated with purified CdiA-CT536 where indicated (+CT), and cell growth was monitored by OD600 measurements. A) E. coli X90 (bamA+) and bamA101 mutants. B) E. coli X90 ΔtolA mutants. C) E. coli X90 ΔtonB mutants. D) E. coli X90 ΔtolA ΔtonB mutants.
