Production of glycopeptide derivatives. (A) eDNA-derived glycopeptide gene cluster and scheme showing the creation of the ermE* promoter-driven tailoring enzyme construct. (B) Bioinformatically predicted functional group modifications encoded by this glycopeptide gene cluster. (C) Conjugation of the ermE* promoter-driven tailoring construct into S. toyocaensis:ΔStaL resulted in the production of three new glycopeptide derivatives (peaks 1–3) (A = dsA47934). (D) Structure for compound 1. Functional groups incorporated by eDNA-encoded tailoring enzymes are colored to match ORFs in A and predictions in B.
