Potassium channel selectivity filter dynamics revealed by single-molecule FRET, Published online: 04 March 2019; doi:10.1038/s41589-019-0240-7
Single-molecule FRET shows that a loop, which forms the selectivity filter in the bacterial inwardly rectifying K+ channel KirBac1.1, transitions between constrained and dilated conformations depending on ion occupancy of the filter.
