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 ... WebJan 30, 2024 · Exogenous carbon-mediated inactivation by aminoglycoside antibiotics is attributed to elevated NADH and proton motive force (PMF) generation and increased antibiotic uptake ( 10 – 13 ), which is supported by metabolic modulation, including promotion of the tricarboxylic acid (TCA) cycle ( 11, 12 ).
