Resolving Linear and Non-Linear Interactive Kinetic Mechanisms for Ions in Membrane Channels
Thallous ion in gramicidin channels displays the anomalous molefraction effect and other behavior that suggests its permeationmechanism might be more complicated than the mechanisms for sodiumor potassium ion ...

Charge dissociation and the rising phase of gating currents
Gating currents from voltage-sensitive channels are generally attributed to the translocation or redistribution of ionic charge associated with the channel molecule. Such charge moves in the direction of the a...

Cooperative denaturation kinetics of homogeneous polymers
The kinetics of denaturation of a homogeneous, helical biopolymer with nearest neighbor interactions are described, using a kinetic Ising model in which the configuration of its neighbors dictates the transiti...

Gating molecule interactions in K+ channels. A consistent explanation for cole-moore shifts and potential ramp experiments
The enhanced induction period of potassium channel currents in squid giant axon induced by hyperpolarizing prepulses (the Cole-Moore shift) is observed and analyzed for a range of depolarizing step potentials....

Properties of membrane stationary states. 2. The isobaric isothermal ensemble
A multi-state membrane transport system serves as the basic model for a comparison of equilibrium and stationary state distributions of ions within an ensemble of membrane channels. Transition probabilities fo...

Properties of membrane stationary states
The flux of permeant species through a membrane is examined using discrete state stochastic models for the transport process within the membrane. While a membrane flux is maintained due to a concentration grad...
