Metallo-enzymes and Cells for Green Environmental Alternatives

ongoing

"""By far, nature is the best chemist of all time"" according to Nobel Prize winner Frances Arnold. McGEA will develop nature inspired strategies to help avert the pending climate catastrophe. We will discover, characterize, engineer and exploit metalloenzymes as potent biocatalysts to efficiently perform chemically challenging reactions of high environmental impact. Specifically, we will use metalloenzymes to tackle three burning issues that fall squarely in the remit of the EU Green Deal action plan: CO2 capture, (bio)hydrogen production, and wastewater monitoring and remediation. These challenges will be addressed using purified metalloenzymes incorporated into hybrid materials and live bacterial cells as self-regenerating catalytic metalloenzyme carriers. Implementation of these two strategies will proceed with research activities across the full pipeline of metalloenzyme development. This will include i) the assembly of the metallic co-factors, as a prerequisite for establishing protocols for efficient metalloenzyme production, ii) rational redesign, directed evolution and in silico strategies to develop enzyme variants that show improved catalytic activity and stability, and iii) the incorporation of the enzymes into matrices that allow for enzyme reusability, stabilization, or their self-assembly into multi-enzymatic nanostructures for substrate channeling. The execution of this program relies on a strong interdisciplinary and intersectoral team. The McGEA brings together 6 research groups from EU and 2 research groups from overseas, all of them internationally recognized for their scientific excellence, and 3 EU companies that will join forces to accelerate the transition to a climate-neutral Europe. The consortium is designed to provide a diverse portfolio of skills through staff secondments to achieve integration from the stages of fundamental scientific discovery to the development of metalloenzyme-based processes and prototype devices."
