Figure 2

Side view of ChTX in complex with a KcsA potassium channel surrogate. ChTX backbone is shown in yellow and the side chains of K11′, K27′, R25′, and R34′ residues involved in the binding are explicitly shown. Two of the four monomers in KcsA (B and D) are shown clearly. The monomer A is removed and C is shown as a shadow for clarity. The carbonyl groups in the filter and the side chains of D80 and D64 residues are explicitly indicated. The water molecules in the filter and two K+ ions (one at the S4 binding site and one in the cavity) are also shown.
