The relative proton stoichiometries of the mitochondrial proton pumps are independent of the proton motive force.
Several different proton pumps were used to generate a proton motive force (delta p, proton motive force across the mitochondrial inner membrane) in isolated rat liver mitochondria, and the relationship between delta p and pump rate was investigated by titrating with various inhibitors of the pumps. It was found that this relationship was the same for mitochondria respiring on succinate irrespe...
متن کاملEnergizing porters by proton-motive force.
It is generally accepted that the chemistry of water was the most crucial determinant in shaping life on earth. Among the more important chemical features of water is its dissociation into protons and hydroxyl ions. The presence of relatively high proton concentrations in the ambient solution resulted in the evolution of proton pumps during the dawn of life on earth. These proton pumps maintain...
متن کاملTransport of amino acids in Lactobacillus casei by proton-motive-force-dependent and non-proton-motive-force-dependent mechanisms.
Lactobacillus casei 393 cells which were energized with glucose (pH 6.0) took up glutamine, asparagine, glutamate, aspartate, leucine, and phenylalanine. Little or no uptake of several essential amino acids (valine, isoleucine, arginine, cysteine, tyrosine, and tryptophan) was observed. Inhibition studies indicated that there were at least five amino acid carriers, for glutamine, asparagine, gl...
متن کاملMembrane deinsertion of SecA underlying proton motive force-dependent stimulation of protein translocation.
The proton motive force (PMF) renders protein translocation across the Escherichia coli membrane highly efficient, although the underlying mechanism has not been clarified. The membrane insertion and deinsertion of SecA coupled to ATP binding and hydrolysis, respectively, are thought to drive the translocation. We report here that PMF significantly decreases the level of membrane-inserted SecA....
متن کاملA bestrophin‐like protein modulates the proton motive force across the thylakoid membrane in Arabidopsis
During photosynthesis, photosynthetic electron transport generates a proton motive force (pmf) across the thylakoid membrane, which is used for ATP biosynthesis via ATP synthase in the chloroplast. The pmf is composed of an electric potential (ΔΨ) and an osmotic component (ΔpH). Partitioning between these components in chloroplasts is strictly regulated in response to fluctuating environments. ...
