The Finnish BAG encompasses 24 groups active in crystallography in Finland. The projects vary widely and include membrane proteins and protein complexes, other proteins involved in disease and antibiotics and drug development and discovery (endoplasmic regulation and protein secretion, ADP-ribosylation and several oncogenic proteins including kinases, biocatalysis) and several pathogen proteins and various enzyme targets and e.g. studies on phytochrome photoreceptors and complexes involved in actin dynamics regulation. Overall the BAG serves the national needs for highly variable projects, with different biological and biotechnological applications. Several project will benefit from microfocus beam lines and tunable wavelength options for phasing, others benefit from quick robust screening by MASSIF. Biology lab is needed for SAXS experiments.
