Directed evolution rendered P450BSβ capable of β-hydroxylating unactivated C−H bonds in aliphatic carboxylic acids with broad substrate scope and excellent chemo-, regio-, and enantioselectivity. The crystal structure of the evolved variant rationalizes the improved reactivity and selectivity. This study demonstrates the potential of exploring biocatalysts to fulfill reactions that are otherwise elusive
