The long-range goal of our research is to advance an understanding of the interactions between pathogens and hosts, in order to describe mechanisms of pathogen engagement of target cells and to provide a basis for vaccine and drug design. We study viruses as well as bacterial pathogens. We use protein crystallography, in combination with other structural approaches and associated biochemical techniques, to establish the three-dimensional structures and function of bacterial and viral proteins, often in complex with cognate ligands such as cellular receptors or substrates.
A particular emphasis is placed on understanding basic principles of protein-protein and protein-carbohydrate interactions. Many such interactions are well characterized at a functional level, yet poorly understood at the molecular or atomic level. However, such knowledge is needed to develop compounds that are able to modulate or block biological interactions. For example, by studying the determinants of viral attachment to host cells and establishing principles of attachment, one can develop molecules that interfere with binding. Likewise, unravelling the structures and mechanisms of bacterial enzymes enables us to interfere with reactions that are critical for bacterial survival and fitness.
