Structure of the pentameric assembly of α2 nAChR ECD in complex with epibatidine and comparison with related structures. (A) Side view and (B and C) top view of the α2-Epi structure; each subunit is colored differently; the epibatidine molecule is shown in orange spheres (B) or by the 2Fo-Fc electron density contoured at 1.4-σ level (C). (D) Superposition of the α2-Epi structure (green) with α7-AChBP chimera (cyan), Ac-AChBP (magenta), both in complex with epibatidine and Torpedo nAChR (blue).
