Academic interests

The protein crystallography group of Ute Krengel uses X-ray crystallography to determine the molecular structures of proteins at atomic resolution.The main focus is on proteins of medical interest and in particular on protein-carbohydrate interactions.

Significance of the Scientific Problem and Potential Applications

Protein-carbohydrate interactions are central to many biological processes (e.g. cell-cell interaction, cellular signaling and differentiation, immune response) that are at the core of important diseases. Understanding the roles of carbohydrates in these processes and how they interact with proteins is expected to have a large impact on the development of new treatments against many human diseases.

The work involves the close collaboration with research groups of different specializations (e.g.biochemists, molecular modelers, bioinformaticians, NMR and mass spectrometrists), thus warranting that the structural characterization of the chosen research targets can be pursued hand in hand with protein engineering and carbohydrate binding studies, microcalorimetry and molecular modeling.

Main targets currently under investigation

Legume and mushroom lectins, adhesins, toxins, mucins, and anti-cancer antibodies.
