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