Ion binding sites occupancy of the MthK SF as a function of the channel opening. A given site (a S1, b S2, c S3, and d S4) can be occupied by a K+ ion (purple), water (red), or be vacant (not shown), summing up to the total occupancy of 1. The openings for which the highest currents were recorded are shown as vertical lines. Error bars represent 95% confidence intervals. Source data are available as a Source Data file.
