glutamate dehydrogenase/glycine max

The growth yields of three strains of Rhizobium japonicum (CB 1809, CC 723, CC 705) in culture solutions containing L-glutamate were about twice those grown with ammonium. The activities of glutamine synthetase (GS; EC 6.3.1.2) and glutamate dehydrogenase (GDH; EC 1.4.1.4) were dependent on the

Glutamate dehydrogenase (EC 1.4.1.2) is a multimeric enzyme that catalyzes the reversible amination of α-ketoglutarate to form glutamate. We characterized cDNA clones of two Glycine max sequences, GmGDH1 and GmGDH2, that code for putative α- and β-subunits, respectively, of the NADH dependent

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

Proteins in extracts from cotyledons, hypocotyls, and roots of 5-d-old, dark-grown soybean (Glycine max L. Merr. cv Williams) seedlings were separated by polyacrylamide gel electrophoresis. Three isoforms of glutamate dehydrogenase (GDH) were resolved and visualized in gels stained for GDH activity.

Bacteroids in ineffective (nitrogenase negative) nodules of Glycine max, infected with Rhizobium japonicum 61-A-24, as compared to those in effective nodules are characterized by reduced specific activities of alanine dehydrogenase to 15%, of 3-hydroxybutyrate dehydrogenase to 50%, and an increase

The subcellular distribution of l-glutamate dehydrogenase (GDH, EC 1.4.1.3.) was studied in SB3 soybean (Glycine max) cells using subcellular fractionation techniques. Compounds that inhibit protein synthesis either on 80s or 70s ribosomes were also used to give a preliminary idea of which

The pattern of assimilation of NH(4) (+) by Alnus glutinosa, a N(2)-fixing, nonleguminous angiosperm, was examined. Detached nodules, roots, and nodulated roots of intact plants were exposed to (13)NH(4) (+) for up to 15 minutes. Glutamine was the most highly labeled compound at all times; the only

The effect of various day temperatures on NADH-nitrate reductase, NADH- and NADPH-glutamate dehydrogenases, nitrate, protein and leaf area, measured at intervals during the ontogeny of the first trifoliolate soybean leaf, was determined. At 32.5 C and 25 C, nitrate concentration, nitrate reductase,

The enzymes involved in the assimilation of ammonia by free-living cultures of Rhizobium spp. are glutamine synthetase (EC. 6.o.I.2), glutamate synthase (L-glutamine:2-oxoglutarate amino transferase) and glutamate dehydrogenase (ED I.4.I.4). Under conditions of ammonia or nitrate limitation in a

Primary roots of soybean [Glycine max (L.), cv Harosoy 63] seedlings were inoculated with zoospores from either race 1 (incompatible, host resistant) or race 3 (compatible, host susceptible) of Phytophthora megasperma f. sp. glycinea (Pmg) and the activities of phenylalanine ammonia-lyase (PAL),

The influences of low root temperature on soybeans (Glycine max [L.] Merr. cv. Wells) were studied by germinating and maintaining plants at root temperatures of 13 and 20 C through maturity. At 42 days from the beginning of imbibition, 13 and 20 C plants were switched to 20 and 13 C, respectively.

The specific activities of glutamate synthase|EC 2.6.1.53, l-glutamine: alpha-ketoglutarate amino transferase (NADPH-oxidising)| and glutamine synthetase|EC 6.3.1.2, l-glutamate: ammonia ligase (ADP-forming)| extracted from soybean (Glycine max L.) cells grown in modified B5 medium were found to

Soybean (Glycine max L. cv. Mandarin) and wheat (Triticum monococcum L.) cells were grown in media with NO3 (-) plus NH4 (+) (B5) and NO3 (-) without NH4 (+) (B5-NH4) as nitrogen sources. Changes in pH, [NO3 (-)] and [NH4 (+)] in media, and dry weight, protein content, nitrate reductase (NR) and

Ultraviolet-B (UV-B, 280-320 nm) radiation has seriously affected the growth of plants. Finding the technology/method to alleviate the damage of UV-B radiation has become a frontal topic in the field of environmental science. The pretreatment with rare earth elements (REEs) is an effective method,

Nitrogen metabolism is not only one of the basic processes of plant physiology, but also one of the important parts of global chemical cycle. Plant nitrogen assimilation directly takes part in the synthesis and conversion of amino acid through the reduction of nitrate. During this stage, some key
