Our research focus: Understanding the motion of proteins at atomic resolution and the link to molecular function

Understanding protein function at atomic level requires the characterization of protein structure, dynamics and interaction at atomic resolution. While the knowledge of the three-dimensional structures of biomolecules is an important step towards this understanding, many interesting biomolecular processes require that biomolecules dynamically explore a range of different conformational states.

Our main research interest is the characterization of proteins that rely on motion to perform their function. In particular, we are interested in understanding the mechanisms by which membrane proteins transport metabolites through the phospholipid bilayer, and furthermore the modes of action of chaperones interacting with aggregation-prone molecules. We use Nuclear Magnetic Resonance spectroscopy, both in the solid-state and in solution-state to probe structure interactions and dynamics in these systems. In parallel and complementary to these studies of biomolecular function, we actively develop and improve NMR techniques, in particular solid-state NMR approaches, which provide insight into biomolecular dynamics at increasing level of detail.

How does the crystal packing influence protein dynamics? Our latest study is out in Nature Communications

Crystallography is based on the inherent assumption that the crystal has only minor effects on the protein, but how well justified is this assumption? Do proteins undergo the same types of motions in solution and in crystals? Are proteins able to undergo slow conformational changes involving the simultaneous reorientation of groups of residues? And is the time scale of such motions altered by the crystal packing? And do the protein molecules as a whole undergo overall-motions?
In our latest study we answer these questions in detail, using three different crystal forms of the same molecule. We show that both the local and the global motion differ in different crystal lattices. Find more in the paper

Native nanodiscs as a tool for membrane protein studies

Atomic-resolution studies of membrane proteins generally suffer from the need to extract the protein from its native lipid environment, which can introduce perturbations of structure and dynamics. We show that the use of a polymer allows to extract directly a patch of native membrane with the protein embedded, and this type of native nanodiscs enable high-resolution solid-state NMR studies, opening possibilities for probing structure, interactions and dynamics of membrane proteins in a near-native environment.

Sensitive solid-state NMR of large proteins through methyl labeling

Studying very large protein complexes is enabled by selective methyl labeling. We recently showed that CH3 labeling provides highly sensitive spectra of protein assemblies from several hundred kilodaltons to a megadalton.
