Research Overview
The department Structural and Medicinal Biochemistry focuses on the elucidation of protein-protein and protein-ligand interactions using biochemical and biophysical strategies in addition to NMR as the main tool for the structure determination of biomolecules. Our research is geared towards predominantly human enzymes/proteins and their macromolecular complexes involved in posttranslational modification processes.
- Protein Structure Determination
- Biochemical Characterisation of Parvulins
- Biophysical studies on the interaction of synthetic supramolecular ligands and proteins

DFG fördert Studie zu Schilddrüsenhormonen Neue Therapien vermutet
[10.04.2024] Die Deutsche Forschungsgemeinschaft (DFG) fördert ein Wissenschaftsteam der Medizinischen Fakultät der Universität Duisburg-Essen (UDE) bei der Forschung an neuen therapeutischen Anwendungsgebieten für Schilddrüsenhormone. Dr. Sebastian Hönes von der Klinik für Endokrinologie, Diabetologie und Stoffwechsel des Universitätsklinikums Essen (UK Essen) leitet die klinische Studie. Die Erkenntnisse sollen potenziell zu neuen Behandlungsmethoden führen, beispielsweise bei Herzinfarkt, Schlaganfall oder Stoffwechsel-Erkrankungen. Für sein Vorhaben erhält Dr. Hönes von der DFG eine Förderung von knapp 300.000 Euro über einen Zeitraum von drei Jahren.
