Fluorinases offer an environmentally friendly alternative for selective fluorination under mild conditions. However, their diversity is limited in nature and they have yet to be engineered through directed evolution. Herein, we report the directed evolution of the fluorinase FlA1 for improved conversion of the non‐native substrate 5′‐chloro‐5′‐deoxyadenosine (5′‐ClDA) into 5′‐fluoro‐5′‐deoxyadenosine
