These three entries focus on the binding mode and interactions in the proximity of the ligands. The medium to low resolution of the crystallographic data (3.3, 2.95 and 2.8 A) and the limited quality and extent of the available data, especially for entry 2fix, should be considered when trying to extract accurate interatomic distances between the ligands and the protein, at certain regions of the protein exposed to solvent.
