title: Cation-binding location and hydrogen-exchange sites for gramicidin in SDS micelles using NOESY NMR.
abstract: The site of monovalent cation binding and sites of hydrogen exchange between amide protons and water molecules in the gramicidin A and Phe-1 gramicidin A channels incorporated into SDS micelles have been determined using a NOESY NMR technique. The cation-binding pocket was found to involve residues 10-15 of the peptide.
