The Microbial Metalloenzymes laboratory engineers metalloenzymes to elucidate the underlying principles and mechanisms of metalloenzyme catalysis. The Rebelein group focuses on the activation of nitrogen and carbon dioxide by the enzyme nitrogenase. Harnessing theses insights, we engineer and design metalloenzymes to develop improved catalysts for the production of bulk chemicals, including fertilizers, hydrocarbons and hydrogen. The long-term goal is to develop semi-artificial metalloenzymes as building blocks for the construction of novel metabolic pathways in synthetic organisms. This synthetic biology approach will help us to construct microbes with artificial traits for the production of bulk chemicals, fuels and the sequestration of CO2.
