Figure 2. Binding of (A) α-conotoxin Vc1.1 (orange) at the α9(+)-α9(−) interfaces of the human α9α10 nAChR, with the binding sites of positions 4 (B), 6 (C), 10 (D) and 11 (E) magnified. Only the side chains of selected residues on the subunit of the α9(+)-α9(−) binding sites are shown. Hydrogen bonds are shown as yellow dashed
