- Position: Professor
His primary research interests lie at the intersection of enzymology and structural biology. He investigates the mechanisms of metalloenzymes, with a particular focus on reductive CO/CO₂ metabolism in bacteria. His work delves into molybdoenzymes, iron-sulfur clusters, and flavoenzymes, exploring how oxidation state influences biological host-guest recognition. A central technique in his research is X-ray crystallography, which he uses to visualize the atomic details of enzyme mechanisms and their reactive intermediates.
An analysis of his recent publications reveals a consistent focus on understanding the structure-function relationships in complex metalloenzymes. His work often employs a multidisciplinary approach, combining high-resolution structural data from crystallography with spectroscopic methods and biochemical assays. The articles cover a range of specific topics, including the catalytic mechanisms of carbon monoxide dehydrogenase, the dynamics of the photosystem II subunit PsbO, and the redox chemistry of molybdenum cofactors in formate dehydrogenase. This indicates a deep expertise in the structural enzymology of redox processes.
While no specific awards are mentioned in the provided text, his sustained leadership role in UniCat and his publication record in high-impact journals are strong indicators of his scientific standing. His research has significant implications for understanding fundamental biological processes related to energy metabolism and has potential applications in environmental science and biotechnology.
Professor Dobbek leads an active research group, as evidenced by his numerous collaborative publications with coworkers. His work is often conducted in collaboration with other leading scientists in the Berlin area, such as Athina Zouni and Peter Hildebrandt, forming a strong network in the field of bioenergetics and catalysis. His lab is equipped to handle the challenges of working with oxygen-sensitive metalloenzymes, a key aspect of his research on iron-sulfur and molybdenum-containing proteins.
