Raw diffraction images of 4-Methoxybenzamidine-bound trypsin

Trypsin is an enzyme in the first section of the small intestine that starts the digestion of protein molecules by cutting these long chains of amino acids into smaller pieces. We used datasets to investigate the protocol of detecting polymorphs using Hierarchical clustering (Acta D., submitted). All diffraction data were collected at BL32XU, SPring-8, using an automated data collection system <em>ZOO</em>. Data were acquired from four crystals of 4-Methoxybenzamidine -bound trypsin. All datasets were collected using a continuous helical scan scheme for 360º oscillation with the following experimental parameters; Beam size: 10 µm × 15 µm, Wavelength: 1.0000 Å, Total dose/crystal: 10 MGy, Detector: EIGER X 9M (DECTRIS Co. Ltd.). All crystals belonged to space group P212121 with unit cell parameters roughly corresponding to a=54.6, b=58.6, c=66.7 Å.
