This periplasmic binding protein, part of the oligopeptide permease system of Gram negative bacteria, has evolved to bind and enclose small peptides of widely varying sequences. The peptides used in this study have the sequence Lys-X-Lys, where X is any of the 20 commonly occurring amino acids. The various side-chains found at position 2 on the ligand fit into a hydrated pocket. The majority of side-chains are restrained to particular conformations within the pocket. Water molecules act as flexible adapters, matching the hydrogen-bonding requirements of the protein and ligand and shielding charges on the buried ligand. This use of water by OppA to broaden the repertoire of its binding site is not unique, but contrasts sharply with other proteins which use water to help bind ligands highly selectively. Predicting the thermodynamics of binding from the structure of the complexes is highly complicated by the influence of water on the system."xsd:string |
