A nucleosidic antibiotic angustmycin C, which is an analogue of adenosine and which has an unusual hexose, psicofuranose, instead of ribose, was confirmed to be incorporated into RNA in Escherichia coli. After incubation of cells with tritiated angustmycin C, small but significant radioactivity was found in RNA fraction. When the RNA was hydrolyzed by an enzyme mixture of snake venom, pancreatic ribonuclease I and alkaline phosphatase, intact angustmycin C was recovered which indicated incorporation of the antibiotic intc the polyribonucleotide chain of RNA.
