1) is well conserved in the K+ channel family. KcsA is a prokaryotic channel (LeMasurier et al., 2001) that has served as a much needed “user friendly” model system for potassium channel research. In the prototypical pore domain, two transmembrane helices (LeMasurier et al., 2001) ...
Ion channels catalyze the selective transfer of ions across the membrane in response to a variety of stimuli. These channels gate by controlling the access of ions to a centrally located water-filled pore. The crystal structure of theStreptomyces lividanspotassium channel (KcsA) has allowed a molec...
We have shown that bacterial K + -channel KcsA, which acts as a representative model for ion channels, forms salt-induced large conductive complexes in a particular environment. In the present study, we investigated the effects of point mutations in the selectivity filter of KcsA on intrinsic ...
Ion conduction and selectivity properties of KcsA, a bacterial ion channel of known structure, were studied in a planar lipid bilayer system at the single-channel level. Selectivity sequences for permeant ions were determined by symmetrical solution conductance (K(+) > Rb(+), NH(4)(+), Tl(...

Channel gating has been the subject of extensive research, and molecular explanations for gating have focused on two KcsA domains. One is the selectivity filter, where the K+-dependent backbone conformation of the filter and pH-dependent changes in the pore helix have been shown to influence the...
single channel currentAtomic resolution structures have provided significant insight into the gating and permeation mechanisms of various ion channels, including potassium channels. However, ion channels may also be regulated by numerous factors, including the physiochemical properties of the membrane in ...
