Functional Role and Affinity of Inorganic Cations in Stabilizing the Tetrameric Structure of the KcsA K(+) Channel
Crystal structures of the tetrameric KcsA K(+) channel reveal seven distinct binding sites for K(+) ions within the central pore formed at the fourfold rotational symmetry axis. Coordination of an individual K(+) ion by eight protein oxygen atoms within the selectivity filter suggests that ion-subun...
