for the construction of chemical bonds. Here we show that Pseudomonas savastanoi ethylene-forming enzyme (PsEFE), a non-heme iron enzyme, can catalyze olefin aziridination and nitrene C-H insertion, and that these activities can be improved by directed evolution. The non-heme iron center allows for facile modification of the primary coordination sphere by addition of metal-coordinating molecules, enabling
