Oxidativephenolcouplingreactions are required to establish the cross‐linked heptapeptide backbone of vancomycin. The first cross‐linking reaction, catalyzed by the P450 enzyme OxyB, is dramatically slower when a chlorine substituent is present in the hexapeptide‐S‐PCP substrate and is abolished when chlorine is introduced into a potential heptapeptide‐S‐PCP substrate.
