We also docked HEPES to the receptors, since this ligand was found in the crystal structure of AChBP.
Previous reports have shown on other systems that a single-residue mutation in a receptor is sufficient for the development of specific ligands [ 13 14 ] . Based on the recent crystal structure of AChBP, we could propose a detailed description of the structural variations of nAChR subtypes.
Low-energy conformations were found only in the absence of water molecule, and the calculated binding energies (Table 1- bottom) suggest that HEPES is a poor ligand for nAChRs, and AChBP, and was observed in the crystal structure because of its high concentration (100 mM) in the crystallization condition [ 6 ] .
R91, E106, F107, W183 and several residues adjacent to the M1 region have all been demonstrated to alter the action of 5-HT and/or m CPBG [ 20 21 25 26 ] . Within the crystal structure of the AChBP, homologous residues are located in the apparent binding site [ 24 ] . The effects of agonist on the 5-HT 3 R are mediated by their interaction with these binding site residues, resulting in stable receptor conformations, including the channel open state.
Surprisingly, the ester moiety of acetylcholine does not seem to interact with the cys-loop of the receptor, as previously suggested by photoaffinity labeling [ 12 ] , but is engaged in similar type of interaction as that observed with the acidic group of HEPES in the AChBP crystal structure [ 6 ] . It is possible that the reactive di-azo group of the photosensitive agonist used in photoaffinity labeling would extend towards the cys-loop, while the conformation of the bound agonist remains in agreement with our model.
