Schematic diagram of the structure of a K+ channel (KvAP) from Streptomyces lividans. A single K+ is shown in a large aqueous cavity inside the
membrane interior. Two helical regions of the channel protein are oriented with their carboxylate ends pointing to where the K+ is located. The channel is
lined by carboxyl oxygen. (Modified, with permission, from Doyle DA, et al: The structure of the potassium channel: molecular basis of K+ conduction and
selectivity. Science 1998;280:69. Reprinted with permission from AAAS.)
