title: Ion channels: a first view of K+ channels in atomic glory.
abstract: Crystal structures have been solved for the transbilayer pore domain of a bacterial K+ channel and the tetramerisation domain of voltage-gated K+ channel. These provide our first real structural insights into possible mechanisms of ion selectivity and permeation for K+ channels.
