The Stockholm BAG is a constellation of seven research groups, whose PIs are affiliated to Karolinska Institutet (Adnane Achour, Jesper Haeggström, Luca Jovine and Robert Schnell) or Stockholm University (David Drew, Martin Hogböm, Pål Stenmark). Together, these groups are responsible for the large majority of the macromolecular crystallography research taking place in the Swedish capital. The scientific interests of the BAG encompass a broad variety of topics that include structural immunology, bacterial adhesion and toxicity, membrane proteins involved in inflammation and transport, fertilization, and enzymatic catalysis relevant to antibiotic production, green chemistry and cancer.
