Frontispiece: Exploring the Biocatalytic Potential of Fe/α‐Ketoglutarate‐Dependent Halogenases

Freestanding Fe/α‐ketoglutarate‐dependent halogenases are interesting development targets as they may serve as valuable tools for the synthesis of high‐value compounds. To date, a small number of indole alkaloid and amino acid halogenases have been identified and characterized. Initial enzyme engineering examples indicate that the accessible substrate range of these enzymes may be expanded whereas their throughout biophysical characterization continues to inform about the principles governing the halogenation mechanism.
