On the problem of biosynthesis of the pyrrolidine ring in nicotine



On the problem of biosynthesis of the pyrrolidine ring in nicotine



Biokhimiia transl 26(1): 70-73



Translated from Biokhimiia 26(1) 82-85. 1961. Ranking the compounds tested on tobacco sprouts by the intensity of incorporation of their isotope into the nicotine, they may be listed in the following descending order: C14-glutamic acid, C14-arginine, 1-C14-leucine, C14-methionine, 2-C14-glycine, 1-C14-glycine. When feedings were made with 1-C14-glycine and 1-C14-leucine the maximum specific radioactivity of nicotine was observed in the 6-day-old sprouts. In the case of 2-C14-glycine, C14-arginine, C14-methionine, and C14-glutamic acid, this was seen in the 8 -day-old sp routs.
