X-RAY STRUCTURE OF ACETYLCHOLINE BINDING PROTEIN (ACHBP) IN COMPLEX WITH NICOTINE
Overview
Nicotinic acetylcholine receptors are prototypes for the pharmaceutically, important family of pentameric ligand-gated ion channels. Here we present, atomic resolution structures of nicotine and carbamylcholine binding to, AChBP, a water-soluble homolog of the ligand binding domain of nicotinic, receptors and their family members, GABAA, GABAC, 5HT3 serotonin, and, glycine receptors. Ligand binding is driven by enthalpy and is accompanied, by conformational changes in the ligand binding site. Residues in the, binding site contract around the ligand, with the largest movement in the, C loop. As expected, the binding is characterized by substantial aromatic, and hydrophobic contributions, but additionally there are close contacts, between protein oxygens and positively charged groups in the ...
