Extended Data Fig. 7: Pseudo-N terminus scanning of the tyrocidine sequence.
From: Non-ribosomal peptide cyclase-directed chemoenzymatic synthesis of lariat lipopeptides

The structure of the d-Phe1′-l-Lys dipeptide unit, the branched EG substrates (18–26), and the cyclization/hydrolysis conversion mediated by TycC-TE are shown.
