Loop C of AcAChBP adopts different conformations. Ribbon representation of loop C segments with the bound agonist epibatidine (cyan, PDB entry 2byq; Hansen et al., 2005), antagonist strychnine (grey, PDB entry 5o8t; Dawson et al., 2019) and the AcAChBP–1 and AcAChBP–3 complexes (red and black, respectively). Compound 3 is shown and coloured with the following scheme: C, black; O, red; N, blue; F, dark green. The overlay was calculated using all Cα atoms of a single subunit. |
