Until now, many drugs such as L-DOPA, a drug for Parkinson's disease, have been based on fossil carbon sources. Due to limited fossil carbon sources, it is an urgent goal to create new synthesis pathways based on sustainable resources. For this approach new catalysts have to be developed. This part of the project will focus on the combination of chemo- and biocatalysis to create an artificial metalloprotein (ArM). By combining the best properties of both worlds in terms of selectivity and activity, a new catalyst for the redox catalysis of biomass-derived alkenes will be developed.
