Iron-sulfur proteins of prokaryotes and eukaryotes
My group discovers and characterizes novel iron-sulfur proteins through a combination of bioinformatic, protein biochemical and spectroscopic approaches. Equally of interest are non-cysteine coordinated Fe/S proteins, catalytically active (dehydratase) Fe/S enzymes and Fe/S biogenesis in the cytosol of eukaryotes. Our results are of importance for a fundamental understanding of bioinorganic cofactors in Life and for biotechnological application.
In collaborative efforts with the laboratories of Prof. Dr. Matthias Boll (Freiburg), Prof. Dr. Gunhild Layer (Freiburg), Prof. Dr. Holger Dobbek, Dr. Berta Martins (both Humboldt University), Prof. Dr. Hans Heider (Philipps University, Marburg) and others we contribute by the determination of cluster type, amount, redox state and function via application of EPR spectroscopy in a wide range of Fe/S proteins from all kingdoms.
Within the TU Kaiserslautern the Schünemann group is our key collaborator for Mössbauer spectroscopy. We enjoy the collaboration with Dr. Ed Reijerse and Prof. Dr. Wolfgang Lubitz (MPI Müllheim) on pulsed EPR spectroscopies and the collaboration with Prof. Mario Piccioli and Prof. Dr. Simone Ciofi-Baffoni (CERM, Florence, Italy) on NMR spectroscopy.
In the Biology department we have ongoing collaborations with Jun. Prof. Dr. Sabine Filker, Prof. Dr. Thorsten Stoeck and Prof. Dr. Nicole Frankenberg-Dinkel.
Mass spectrometry is carried out with the MALDI-TOF mass spectrometer of physical chemistry group in our department (Prof. Dr. Gereon Niedner-Schattenburg) or with the Centre for Mass Spectrometry Analytics (Dr. Markus Raeschle, Prof. Dr. Michael Schroda) in the department of Biology.
