Novartis Foundation symposium, 225, 93-107 (1999-09-03)
Can we use rate constants and state models to describe ion transport through gramicidin channels? Maybe, but only if rate constants are just proportionality constants between rates and probabilities of observing states of the channel. This approach is natural if

The linear gramicidins are peptide antibiotics that form cation-selective channels in lipid bilayers. Gramicidin channels have very well-defined functional characteristics, and the structure of membrane-spanning gramicidin A channels is known at atomic resolution. These features make the gramicidins well suited

Cl- is one of the major ionic constituents of cells and extracellular spaces. Intracellular Cl- plays an important role in regulating the cell volume and pH, in both salt secretion and reabsorption, in membrane excitability, and G-protein-dependent intracellular signal transduction.
