Abstract

We demonstrate novel in vitro halogenation of peptides by halogenase enzymes, and identify the (G/S)GW motif (HaloTryp Tag) as a preferred substrate. We further derive PyrH halogenase mutants showing improved halogenation of the HaloTryp Tag, both as a free peptide and when genetically fused to model proteins.
