The BAG groups 8 teams from 4 Marseille laboratories. Research themes deal with infection, health and biotechnology. For 81 projects within this proposal we foresee 11 MX and 2 SAXS shifts for the next 6 months. This is less of what we had asked for in previous years, given that data collection speed has largely increased and several projects are now being tackled by Cryo-EM. To be added that during the ESRF shutdown all the activities of the BAG have moved to Soleil and the moving back of activities to ESRF is affected by natural inertia. 2 shifts for 6 month at the BIOSAXS beamline, split up in two sessions, suit our needs. Two teams of the BAG combine structural biology with medicinal chemistry and beam time at MASSIF for large ligand-screening campaigns will mostly suit their research purposes. We are grateful to all ESRF staff for always being forthcoming with regard to scheduling, logistics and experiments, allowing the BAG to produce good Science in a comfortable setting.
