C-N-Coupled Metabolites Yield Insights into Dynemicin A Biosynthesis.

Abstract excerpt

The biosynthesis of the three structural subclasses of enediyne antitumor antibiotics remains largely unknown beyond a common C16 -hexaene precursor. For the anthraquinone-fused subtype, however, an unexpected iodoanthracene γ-thiolactone was established to be a mid-pathway intermediate to dynemicin A. Having deleted a putative flavin-dependent oxidoreductase from the dynemicin biosynthetic gene cluster, we can...
