The Chemistry of Biological Processes chair develops research at the interface of chemistry and biology, which forms the basis of its lectures. In particular, this involves studying the structure and mechanism of complex enzymatic systems involved in metabolic and biosynthetic pathways, such as RNA modification or ubiquinone biosynthesis, as well as metalloenzymes of bioenergetic metabolism such as hydrogenases, which catalyze the reduction of water to hydrogen. Questions of catalysis for energy storage, in the field of artificial photosynthesis, are addressed by multiple approaches in synthetic chemistry, electrochemistry and photochemistry, combining bioinspired molecular chemistry, solid-state chemistry and hybrid chemistry (combining molecular components with organic-inorganic solids). New catalysts are being developed for the oxidation of water (catalysts for the anode of electrolyzers), the reduction (catalysts for the cathode of electrolyzers) of protons to hydrogen and of carbon dioxide to organic compounds of economic interest, notably hydrocarbons such as ethylene or alcohols such as ethanol.
