This BAG application gathers most danish esrf users with the area of structural biochemistry (including both crystallography, cryoEM and SAXS). 4 PIs work with carbohydrate active enzymes of all classes, with particular focus on biotechnological applications and gut microbiota. 6 PIs work in the important membrane proteins area, with both receptors and transporters as main focus, almost all potential or current drug targets. Other groups (5 PIs) work on non membrane proteins which are also potential drug targets or anyway systems potentially involved in disease - enzymes, bacterial antibiotic resistance and survival, DNA binding proteins and other r egulators, immune system components. One crystallographic method development project is also included (1 PI), as are two bioSAXS projects (2 PIs) regarding fibrillation and formulation. Some PIs in the BAG work of course in several of these main research areas.
