WebbThey comprise a broad range of diseases caused by microorganisms, chemicals, toxins, radioactivity, or even physical agents present in ingested food or water. Foodborne illnesses constitute a public health problem since they boost morbidity and mortality, causing a significant number of hospitalisations and deaths [ 5, 12, 13 ]. WebbProton motive force is the force which results from an electrochemical gradient of protons across a membrane and which can be used to drive ATP synthesis and certain other …
WebbThe proton-motive force created by the pumping out of protons by the respiratory chain complexes is in the mitochondria of most tissues mainly used to translocate protons … WebbThe 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 ΔtolA ΔtonB target cells are fully sensitive to CDI.
