Pyrrolo[1,4]benzodiazepine antibiotics. Biosynthesis of the antitumor antibiotic 11-demethyltomaymycin and its biologically inactive metabolite oxotomaymycin by Streptomyces achromogenes.
11-Demethyltomaymycin, an antitumor antibiotic produced by Streptomyces achromogenes, and its biologically inactive metabolite oxotomaymycin are biosynthesized from L-tyrosine, DL-tryptophan, and… Expand
Pyrrolo[1,4]benzodiazepine antibiotics. Biosynthesis of the antitumor antibiotic sibiromycin by Streptosporangium sibiricum.
The biosynthesis of the antitumor antibiotic sibiromycin by Streptosporangium sibiricum requires the construction of four units: the amino sugar from glucose; the anthranilate ring from DL-tryptophan… Expand
