Research Abstract |
Hydrophobic interactions are known to be essential for biomolecular recognition. In this project, our hypothesis that concerted bimolecular movements lead to stabilization of complexation was confirmed by experimental data. Fatty acid and fatty-acid binding proteins were subjected to the structural determination by X-ray analysis. The results clearly showed that fatty acids with an alkyl chain longer than C14 have highly flexible conformation around their terminal methyl group. These movements of alkyl chains hardly prevent high affinity of fatty acids, thus supporting that a rapid movements of ligand molecules do not always decrease bimolecular affinity but stabilize the ligand binding.
