Molecular Recognition and Catalysis

Marcus Hartmann

Our mission is to understand and manipulate macromolecular machines and systems. For their understanding, we follow a holistic approach, in which we integrate a variety of structural methods with biochemical, biophysical and computational approaches. For their manipulation, we exploit our findings for drug discovery and development, often in collaboration with medicinal chemists.

Research focus

Our group maintains two main lines of research. The first line focusses on basic research on the spatial organization, functional dynamics, and druggability of biomolecular interactions in metabolic pathways, molecular signaling processes and macromolecular complexes. The second line focusses on individual pharmacological targets, with a strong emphasis on targeted protein degradation via the repurposing of E3 ubiquitin ligases.

Investigational approach

We generally rely on the integration of complementary methods to obtain insight into dynamics and to overcome technical artifacts of individual methods. For structural characterization, we routinely employ X-ray crystallography, SAXS, and - in collaboration - NMR and Cryo-EM, which we complement with computational approaches. For drug targets, we dissect the structure-activity relationship of small molecules using X-ray crystallography and develop bespoken biophysical assays.
