[Effect of pH on the potential-dependent functioning of staphylococcal toxin channels in phosphatidylcholine bilayer].
Potential-dependence of staphylococcal toxin channels at neutral pH is poorly expressed and increases with the medium acidation. It is shown that the value of the translocating charge is practically unchanged, whereas the energy parameters of this process vary essentially. The data obtained indicate the asymmetrical disposition of ionogenic channel groups determining its behaviour in the electric field.
