| Abstract: | reaction: see text] The incorporation of (15)N, (18)O]-isobutylhydroxylamine into the antibiotic valanimycin by Streptomyces viridifaciens has been shown to proceed with loss of the (18)O label, thereby demonstrating that the azoxy oxygen atom of valanimycin is not derived from the oxygen atom of isobutylhydroxylamine. |
