Dynamic Control of Metabolic Networks
Dr. Hannes Link
Metabolic networks respond rapidly to internal and external perturbations by changing fluxes, metabolite concentrations and enzyme levels. Our group is interested in the regulation of these responses and their functional relevance in microbes. Therefore, we investigate known metabolic control circuits, map novel regulatory interactions and engineer synthetic metabolic regulation. The ultimate goal is to improve metabolically engineered strains by enabling self-optimization of overproduction pathways for chemicals.
