Fig. 4: 1PBC binding site.
From: Inhibition mechanism of the chloride channel TMEM16A by the pore blocker 1PBC
a Position of 1PBC in the binding pocket viewed from the extracellular side. Molecular boundaries are represented as green surface. b Detailed view of residues in contact distance to 1PBC. A putative salt bridge between Lys 603 and the 1PBC hydroxyl is indicated. c Schematic contact map between 1PBC and selected surrounding residues.
