(a) A Cα trace of the AcAChBP pentamer. Different colors distinguish the subunits. The positions of the orthosteric sites are indicated by (−)-hosieine-A depicted as van der Waals spheres with C atoms in gray, O atoms in red and N atoms in blue. (b) A schematic showing the loops and key residues of the orthosteric site formed between the yellow (+) and green (−) subunits, which contribute the principal and complementary sides, respectively. |
