The linear peptide gramicidin forms prototypical ion channels specific for monovalent cations and has been extensively used to study the organization, dynamics and function of membrane-spanning channels. In recent times, the availability of crystal structures of complex ion channels has

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

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

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.

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.
