[Transmembrane electric potential as a regulator of functional activity of biomembranes].
The role of the transmembrane electric potential difference in producing structural tension of biological membranes is analysed. A suggestion is made that delta psi can optimize conditions of protein-protein interactions by ordering the membrane lipid. For energy-coupling membranes this makes it possible to explain the dependence of ATP synthesis on both electron transport and delta psi in terms of local bioenergetic coupling. The energized biomembrane is considered as a self-supporting structure, delta psi being a regulator of efficiency of molecular machines performing different membrane functions, including energization as well.
