Abstract
Flavipin (I), a metabolic product of Aspergillus flavipes. has been biosynthesized in the presence of I-C14-acetate, 2-C14-acetate, and c14H3-L-methionine. The distribution of radioactivity incorporated into flavipin was determined by chemical degradation. The results obtained clearly indicate that the aromatic nucleus as well as the two formyl groups of flavipin are derived from acetate, in consistence with the acetate-polymalonate theory, while the nuclear methyl group of flavipin was found to be an "introduced" C1-unit.Keywords
