WebThe aerobic electron transport chains generate the cellular proton motive force (pmf), which in turn drives ATP synthesis via ATP synthase. The pmf is also used to power flagella … WebHere, we show that CdiA-CT toxin translocation requires the proton-motive force (pmf) within target bacteria. The pmf is also critical for the translocation of colicin toxins, which exploit the energized Ton and Tol systems to cross the outer membrane. However, CdiA-CT translocation is clearly distinct from known colicin-import pathways because ...
