Energetics of discrete selectivity bands and mutation-induced transitions in the calcium-sodium ion channels family
I. Kaufman, D. G. Luchinsky, R. Tindjong +2
We use Brownian dynamics simulations to study the permeation properties of a generic electrostatic model of a biological ion channel as a function of the fixed charge at its…
Multi-ion conduction bands in a simple model of calcium ion channels
I. Kaufman, D. G. Luchinsky, R. Tindjong +2
We report self-consistent Brownian dynamics simulations of a simple electrostatic model of the selectivity filters (SF) of calcium ion channels. They reveal regular structure in th…
Charge fluctuations and their effect on conduction in biological ion channels
D. G. Luchinsky, R. Tindjong, I. Kaufman +2
The effect of fluctuations on the conductivity of ion channels is investigated. It is shown that modulation of the potential barrier at the selectivity site due to electrostatic am…
Ionic channels as electrostatic amplifiers of charge fluctuations
D. G. Luchinsky, R. Tindjong, I. Kaufman +2
Electrostatic interaction between ions in an ionic channel and the charge fluctuations in the channel mouth are considered. It is shown that the charge fluctuations can be enhanced…
