WebApr 1, 2024 · Bacteria also utilize their membrane potential as a means of signaling and processing information. By depolarizing the membrane potential, bacteria can enter a 'persister' state wherein they are more resistant to antibiotics. Homeostasis of pH is controlled by proton pumps, which maintain a PMF, and is thus dependent on the … WebSep 7, 2024 · To test this hypothesis, we determined the PMF in bacteria after. exposure to increasing concentrations of BEN by monitoring the fluorescence changes of.

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 ). Webpmf on protein localization is widespread among bacteria. Effect on Protein Localization Is Not Restricted to CCCP. To exclude that the observed changes in cellular localization patterns were caused by an unspecific (pmf unrelated) influence of CCCP, we tested other ionophores that are known to dissipate the pmf.
