Figure 3. Docking of Cap-1 (A–C) and Cap+1 (D–F) reveals interacting channel residues and binding poses of agonists.
(A) Representative binding poses of CAP-1 inside the ligand-binding pocket. (B) Energy of predicted VDW and hydrogen bond for each ligand-binding pocket residues. (C) Concentration-response curves of WT and mutant channels in the presence of CAP-1. (D) Representative binding poses of CAP+1. (E) Energy of predicted VDW and hydrogen bond for each ligand-binding pocket residues. (F) Concentration-response curves of WT and mutant channels in the presence of CAP+1. Units of energy are R.E.U. (Rosetta Energy Unit). n = 3–5 cells.
