Application of ¹³C-NMR to the Biosynthetic Investigations. III. Incorporation of Propionate-3-¹³C into Aureothricin

Abstract

Incorporation of propionate into the propionamide of aureothricin (I) has been demonstrated as a result of a comparison of ¹³C-NMR spectra of I in natural abundance level and enriched, which was obtained by feeding sodium propionate [3-¹³C] to the culture of Streptomyces luteoreticuli.
