Beamstops and beamstop shadows can lead to erroneous reflection measurements in crystallographic diffraction experiments, which is a common problem in data processing. Here, a method is presented that combines crystallographic statistics with machine learning to robustly detect such reflections.

Crystal structures of a β-glucosidase from the thermophilic bacterium C. saccharolyticus (Bgl1) and its complex with glucose were determined at 1.47 and 1.95 Å resolution, respectively. Comparison of Bgl1 with sequence or structural homologues showed that Bgl1 is quite similar except for two regions, one of which seems to be a unique insertion of residues that is only present in Bgl1.

A description is given of new deep-learning tools that analyse experimental micrographs of crystallization experiments to enable the automation of outcome classification, crystal detection and determination of locations to dispense compounds for fragment-based drug discovery at Diamond Light Source.
