Effect of Local Binding on Stochastic Transport in Ion Channels
I. Kh. Kaufman, W. A. T. Gibby, D. G. Luchinsky +1
Ionic Coulomb blockade (ICB) is an electrostatic phenomenon recently discovered in low-capacitance ion channels/nanopores. Depending on the fixed charge that is present, ICB strong…
Statistical Theory of Selectivity and Conductivity in Biological Channels
D. G. Luchinsky, W. A. T. Gibby, I. Kaufman +2
We present an equilibrium statistical-mechanical theory of selectivity in biological ion channels. In doing so, we introduce a grand canonical ensemble for ions in a channel's sele…
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…
