S B Hladky
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

Nihon yakurigaku zasshi. Folia pharmacologica Japonica, 113(6), 339-347 (1999-10-19)
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.
R E Koeppe et al.
Novartis Foundation symposium, 225, 44-55 (1999-09-03)
Mutations and chemical substitutions of amino acid side chains and backbone atoms have proved vital for understanding the folding, structure and function of gramicidin channels in phospholipid membranes. The channel's pore is lined by peptide backbone groups; their importance for
T A Cross
Methods in enzymology, 289, 672-696 (1997-01-01)
The method of using orientational constraints derived from solid-state NMR for structural characterization of polypeptides in heterogeneous environments has now been demonstrated. A very high resolution structure has been achieved that has led to greater functional understanding of this channel.
Benoît Roux
Accounts of chemical research, 35(6), 366-375 (2002-06-19)
Ion channels are highly specific membrane-spanning protein structures which serve to facilitate the passage of selected ions across the lipid barrier. In the past decade, molecular dynamics simulations based on atomic models and realistic microscopic interactions with explicit solvent and
