Cisapride low-energy binding mode (a) Structure of the Cisapride-bound channel side view with the extracellular side on the top and 90° rotated extracellular view. (b) A zoomed-in view of the cisapride bound to the central cavity. (c) A 2D representation of cisapride interactions with the residues in the central cavity. (Numbers show the distance between the two groups in angstrom). SF selectivity filter, CC central cavity.
