What is it about?
We develop a new concept to impart new functions to biocatalysts by combining enzymes and metal−organic frameworks (MOFs). The proof-of-concept design is demonstrated by embedding catalase molecules into uniformly sized ZIF-90 crystals via a de novo approach. We have carried out electron microscopy, X-ray diffraction,

Why is it important?
Because catalase is immobilized and sheltered by the ZIF-90 crystals, the composites show activity in hydrogen peroxide degradation even in the presence of protease proteinase K. This proof of concept can be applied in several fields including biomolecular delivery, size-selective enzyme catalysis, and industrial wastewater treatment.
