Molecular dynamics studies of AChBP with nicotine and carbamylcholine: the role of water in the binding pocket.
The acetylcholine-binding protein (AChBP) is homologous to the ligand-binding domain of the nicotinic acetylcholine receptor (nAChR) and other members of the Cys-loop family of neurotransmitter receptors. The high-resolution X-ray structures of AChBP mean it has been used as a model from which to understand agonist and antagonist binding to nAChRs. We present here a molecular dynamics (MD) study of AChBP with nicotine and carbamylcholine bound. Our results suggest that the ligand imposes rigi...Expand abstract
