This BAG application gathers many danish esrf users with the area of structural biochemistry (including both crystallography, cryoEM and SAXS). Some of the work focuses on carbohydrate active enzymes of all classes, with particular focus on biotechnological applications. Several 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 work on non membrane proteins which are also potential drug targets or in some way known to potentially be involved in disease - enzymes, bacterial antibiotic resistance and survival, DNA binding proteins and other regulators, immune system components. One crystallographic method development project is also included as are two principally bioSAXS projects. BioSAXS in addition contributes to several of the other projects, and infact we ask in this round for less Xtal beamtime and more bioSAXS beamtime.
