Introduction of prnA, the halogenase gene from pyrrolnitrin biosynthesis, into Streptomyces coeruleorubidus resulted in efficient in situ chlorination of the uridyl peptide antibotic pacidamycin. The installed chlorine provided a selectably functionalizable handle enabling synthetic modification of the natural product using mild cross-coupling conditions in crude aqueous extracts of the culture broth.
