Our main area of interest and expertise is how protein structure relates to function, in particular in proteins that utilize redox active metal cofactors or radicals for catalysis.



The focus of my research lies on oxygen-activated metalloenzymes. These enzymes facilitate challenging chemical reactions by using the ability of a metal to reversibly assume different redox states. Class I Ribonucleotide reductase produces dNTPS, the building blocks of DNA, by utilizing radical chemistry with the help of a dinuclear metal centre and molecular oxygen. I investigate this enzyme with the help of classical steady-state crystallography, serial-femtosecond crystallography, and spectroscopic methods like UV-VIS spectroscopy and total reflection X-ray fluorescence spectroscopy next to classical biochemical characterization. Methods with these enzymes often require an anaerobic environment, so I am also familiar with setting up an experimental setup in an anaerobic chamber.
