In contrast to vancomycin biosynthesis where halogenation occurred after peptide assembly, substrate selectivity of the teicoplanin and balhimycin NRPS condensation domains would likely dictate that only halogenated tyrosine would proceed along the peptide assembly line for further elongation

Saturation and diminishing returns: Beyond certain dose, additional peptide provides minimal incremental benefit as receptors become saturated or downstream pathways maximally activated
