Nature Catalysis, Published online: 03 November 2025; doi:10.1038/s41929-025-01436-0The creation of artificial metalloenzymes compatible with complex biological settings could enable broad applications. Now a de novo-designed artificial metalloenzyme containing an abiological ruthenium cofactor is reported and optimized for ring-closing metathesis in the cytoplasm of whole cells.
