C-1027 is an enediyne antitumor antibiotic composed of four distinct moieties: an enediyne core, a deoxy aminosugar, a beta-amino acid, and a benzoxazolinate moiety. We now show that the benzoxazolinate moiety is derived from chorismate by the sequential action of two enzymes-SgcD, a 2-amino-2-deoxyisochorismate (ADIC) synthase and SgcG, an iron-sulfur, FMN-dependent ADIC dehydrogenase-to generate 3-enolpyruvoylanthranilate (OPA), a new intermediate in chorismate metabolism. The functional eluci ...[more]
