The biosynthesis of the vancomycin aglycone involves three oxidativephenolcouplingreactions, each catalyzed by a discrete cytochrome P450-like enzyme. Studies on the mechanism and specificity of the enzyme (called OxyB) catalyzing the first coupling, require access to suitable linear peptide precursors, each conjugated as a thioester to a peptide carrier domain of the vancomycin non-ribosomal peptide
