WebbThe proton motive force drives the outer membrane transport of cobalamin in Escherichia coli Author C Bradbeer 1 Affiliation 1 Department of Biochemistry, School of Medicine, University of Virginia Health Sciences Center, Charlottesville 22908. PMID: 8387997 PMCID: PMC204637 DOI: 10.1128/jb.175.10.3146-3150.1993 Abstract WebbSuccinate-driven reverse electron transport (RET) is one of the main sources of mitochondrial reactive oxygen species (mtROS) in ischemia-reperfusion injury. RET is dependent on mitochondrial membrane potential (Δψ m) and transmembrane pH difference (ΔpH), components of the proton motive force (pmf); a decrease in Δψ m and

Webb5 juni 2003 · Oxidative phosphorylation involves the coupling of ATP synthesis to the proton-motive force that is generated typically by a series of membrane-bound electron transfer complexes, which ultimately reduce an exogenous terminal electron acceptor. This is not the case with Pyrococcus furiosus, an archaeon that grows optimally near 100°C. 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.
