Webb5 apr. 2024 · In bacteria, the proton motive force (PMF), the electrochemical potential associated to protons, powers an impressive array of fundamental processes, from ATP production to motility. While far from equilibrium, it has classically been considered homeostatic in time and space. WebbThe CdiA effector extends from the surface of CDI(+) inhibitor cells, binds to receptors on neighbouring bacteria and delivers a toxin domain derived from its C-terminal region (CdiA-CT). Here, we show that CdiA-CT toxin translocation requires the proton-motive force (pmf) within target bacteria.

Webb24 nov. 2024 · November 24, 2024 by Yulios. In photosynthesis, proton motive force is used to produce ATP. ATP is used by cells to power many of their metabolic functions. Proton motive force is created by a proton gradient across a membrane. This gradient is created by the movement of protons from an area of high concentrations to an area of … WebbThe protonmotive force is not a vector force as defined in physics. This conflict is resolved by the generalized formulation of isomorphic, compartmental forces, ∆ tr F, in energy (exergy) transformations [2]. Protonmotive means that there is a potential for the movement of protons, and force is a measure of the potential for motion.
