(a) Comparison of the conserved HHxxxDG region in the C domains of four reported fungal iterative NRPSs. The active site H residues are highlighted. (b) HPLC analysis of the in vitro reaction of C2(BbBEAS) with D-Hiv-SNAC (S1) and N-Me-L-Phe-SNAC (S2). (c) HPLC analysis of the in vitro reaction of C1(BbBEAS) with S1 and S2. (d) HPLC analysis of the in vitro reaction of C1(BbBEAS) with S1 and S4. (e) HPLC analysis of the products of C1-mutated BbBEAS and BbBSLS in S. cerevisiae BJ5464-NpgA.
