The phosphinothricin model was restrained to match small-molecule structure solutions (see article). Some of the closely spaced waters are most likely a MPD molecule, such as O61 & O28. A BULK SOLVENT CORRECTION and an anisotropic B-factor correction was applied to the data set (see XPLOR 3.843). Alternate conformations B reflect the movements of catalytic loops upon phosphinothricin binding in the active site, whereas alternate conformations A reflect a native structure. See article for details.
