New catalytic reactions by directed enzyme evolution
Our research group combines methods from organic chemistry, enzymology and directed evolution to design, evolve, apply and understand new enzyme function. We aim to develop biocatalysts for synthetic organic chemistry catalyzing fundamental C-C, C-N and C-O bond formations that do not have a good catalytic solution. These new enzymes will be applied in synthesis, increase our understanding in enzymology and can expand the metabolism in living organisms.
