Abstract
The identification of new cytosine glycosides and intermediates in the biosynthetic pathway of the antifungal antibiotic blasticidin S (1) was investigated using in vivo enzyme inhibition. Fermentations of Streptomyces griseochromogenes, the organism that produces 1, supplemented with the arginine analogue argininic acid or the argininosuccinate synthase inhibitor 2-methylaspartic acid were found to produce a new metabolite (7).
