l-Canavanine Transport and Utilization in Developing Jack Bean, Canavalia ensiformis (L.) DC. [Leguminosae].
l-Canavanine, the guanidinooxy structural analog of l-arginine, is an important nonprotein amino acid of many leguminous plants with nitrogen storage a major proported role. l-[Guanidinooxy-(14)C]canavanine, [(14)C] urea, and [(15)N]urea were injected separately into the fleshy, green cotyledons of 9-day old jack bean plants, Canavalia ensiformis (L.) DC. [Leguminosae]. There was significant tr...
متن کاملl-Canavanine Metabolism in Jack Bean, Canavalia ensiformis (L.) DC. (Leguminosae).
l-Canavanine, a highly toxic arginine antimetabolite, is the principal nonprotein amino acid of many leguminous plants. Labeled-precursor feeding studies, conducted primarily with [(14)C]carbamoyl phosphate, and utilization of the seedlings of jack bean, Canavalia ensiformis (L.) DC. (Leguminosae), have provided evidence for l-canavanine biosynthesis from l-canaline via O-ureido-l-homoserine. T...
متن کاملCanavanine resistance in Cryptococcus neoformans.
All of the isolates of Cryptococcus neoformans var. gattii which we tested were resistant to greater than or equal to 3.5 mM canavanine. All of the serotype D isolates and 28% of the serotype A isolates of C. neoformans var. neoformans tested were susceptible to less than or equal to 18 microM canavanine, whereas the remaining 72% of the serotype A isolates were as resistant as the C. neoforman...
متن کاملInvestigations of Canavanine Biochemistry in the Jack Bean Plant, Canavalia ensiformia (L.) DC: I. Canavanine Utilization in the Developing Plant.
An ontogenetic study of the canavanine and soluble protein pools in the developing jack bean plant, Canavalia ensiformis (L.) DC., was conducted. Evidence was presented which clearly established the conversion of canavanine to canaline and urea as the principal pathway of canavanine utilization. The catabolic reactions of certain bacteria involving the formation of guanidine or hydroxyguanidine...
متن کاملAlkaloids of the Australian Leguminosae*
Many species of Acacia have been tested by Mr. E. P. White for the presence of alkaloids in plants grown in New Zealand. He identified tryptamine, phenylethylamine, and N-methylphenylethylamine. Acacia kettlewelliae Maiden was found by White1 to oontain about 1.5% base in its leaves and stems, 92% of which was 2-phenylethylamine. A sample of leaves collected at Creswick, Victoria, gave 0.9% bas...
