l-Arginine and l-Canavanine Metabolism in Jack Bean, Canavalia ensiformis (L.) DC. and Soybean, Glycine max (L.) Merr.
Studies have been conducted with the arginase (l-arginine amidinohydrolase, EC 3.5.3.1) of two legumes: jack bean, Canavalia ensiformis (L.) DC., a l-canavanine-containing plant and soybean, Glycine max, a canavanine-free species. Analyses of the arginase obtained from gradient-purified mitochondria of these legumes revealed that the arginine-dependent (ADA) and canavanine-dependent activities ...
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 کاملl-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 کاملAn Ontogenetic Study of Canavanine Formation in the Fruit of Jack Bean, Canavalia ensiformis (L.) DC.
An ontogenetic study of canavanine formation in the fruit of jack bean, Canavalia ensiformis (L.) DC. was conducted. Evidence was presented to show that the ovary wall is the reservoir for seed canavanine. The testa possesses sufficient canavanine to account for the continued elevation in seed canavanine after the pod senesces. The seed canavanine concentration is not constant inasmuch as the c...
متن کاملSoybean [Glycine max (L.) Merr].
In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...
