amide/glycine max

The free amino acid concentrations in cotyledons and axes of soybean (Glycine max [L.] Merr. cv. Wells) seedlings were determined by automated single column analysis after germination at 10 and 23 C. After 5 days germination at 10 C, glutamate and aspartate were in high concentration in both

The localization of urate oxidase (=uricase, E.C. 1.7.3.3) was determined cytochemically in nodules of Sesbania exaltata (Raf.) Cory, soybean (Glycine max [L.] Merr.) and alfalfa (Medicago sativa [L.] ), using the precipitation of peroxide (produced during the oxidation of urate) by cerium chloride.

Partially purified, cell-free extracts from nodules of cowpea (Vigna unguiculata L. Walp. cv. Caloona) and soybean (Glycine max L. Merr. cv. Bragg) showed high rates of de novo purine nucleotide and purine base synthesis. Activity increased with rates of nitrogen fixation and ureide export during

Nodulated and denodulated roots of adzuki bean (Vigna angularis), soybean (Glycine max), and alfalfa (Medicago sativa) were exposed to (14)CO(2) to investigate the contribution of nodule CO(2) fixation to assimilation and transport of fixed nitrogen. The distribution of radioactivity in xylem sap

Amide and ureide biogenic enzymes were measured in the plant fraction of soybean (Glycine max) nodules during the period 11 to 23 days after inoculation with Rhizobium japonicum (USDA 3I1b142). Enzymes involved in the initial assimilation of ammonia, i.e. glutamine synthetase, glutamate synthase,

This study aimed to estimate the proximate, phenolic and flavonoids contents and phytochemicals present in seeds of twenty four soybeans (Glycine max (L.) Merr) genotypes to explore their nutritional and medicinal values. Crude protein composition ranged between 35.63 and 43.13% in Argentinian and

The thermal denaturation behaviour of glycinin solutions has been studied in situ as a function of ionic strength using various spectroscopic methods. Changes in secondary structure occurred at temperatures above 60 degrees C, well before the onset of gelation. Even after heating to 95 degrees C,

BACKGROUND Cyclophilins (CYPs) belong to the immunophilin superfamily, and have peptidyl-prolyl cis-trans isomerase (PPIase) activity. PPIase catalyzes cis- and trans-rotamer interconversion of the peptidyl-prolyl amide bond of peptides, a rate-limiting step in protein folding. Studies have

Soybean (Glycine max) and pea (Pisum sativum) differ in the transport of fixed nitrogen from nodules to shoots. The dominant nitrogen transport compounds for soybean are ureides, while amides dominate in pea. A possible enzymic basis for this difference was examined.The level of enzymes involved in

N2-fixing root nodules of soybean (Glycine max L. Merr.) convert atmospheric N2 to ammonia(um) in an energy-intensive enzymatic reaction. These nodules synthesize large quantities of purines because nitrogen fixed by bacteria contained within this tissue is transferred to the shoots in the form of

Recently, we provided preliminary evidence for calcium (Ca2+)/calmodulin (CaM) stimulation of plant glutamate decarboxylase (GAD; EC 4.1.1.15). In the present study, a detailed characterization of the phenomenon is described. GAD was partially purified from various soybean (Glycine max L. Merr.)

The metabolism of d- and l-methionine by immature cotyledons of soybean (Glycine max, L. cv Elf) grown in culture has been investigated using solid-state (13)C and (15)N nuclear magnetic resonance. d-Methionine is taken up by the cotyledons and converted to an amide, most likely by N-malonylation.

The metabolism of allantoin by immature cotyledons of soybean (Glycine max L. cv Elf) grown in culture was investigated using solid state (13)C and (15)N nuclear magnetic resonance. All of the nitrogens of allantoin were incorporated into protein in a manner similar to that of each other and to the

Solid-state (15)N- and [(13)C] NMR have been used to measure quantitatively the utilization of glycine in the presence of glutamine for the synthesis of storage protein in immature cotyledons of soybean (Glycine max L. cv. Elf) in culture. The presence of an equal molar amount of glycine in the

Under conditions of controlled pH, nitrate and ammonium are equally effective in supporting the growth of young soybean (Glycine max var. Bansei) and sunflower (Helianthus annuus L. var., Mammoth Russian) plans. Soybean contains an active nitrate reductase in roots and leaves, but the low specific
