As biocatalysts, enzymes accelerate many chemical reactions. Researchers at the Karlsruhe Institute of Technology (KIT) have now incorporated enzymes into metal-organic cages (MOFs). They then demonstrated for the first time that stabilization by these framework structures is sufficient for use of the enzymes in a continuously operated reactor. The authors, including Cluster Postdoctoral Researcher Tawheed Hashem and Principal Investigator Christof Wöll, report in the journal Angewandte Chemie.
