Glutamine synthetase (GS; EC: 6.3.1.2, L-glutamate: ammonia ligase ADP-forming) is a key enzyme in ammonium assimilation and metabolism of higher plants. The current work was undertaken to develop a more comprehensive understanding of molecular and biochemical features of GS gene family in poplar, and to characterize the developmental regulation of GS expression in various tissues and at various times during the poplar perennial growth. The GS gene family consists of 8 different genes exhibiting all structural and regulatory elements consistent with their roles as functional genes. Our results indicate that the family members are organized in 4 groups of duplicated genes, 3 of which code for cytosolic GS isoforms (GS1) and 1 which codes for the choroplastic GS isoform (GS2). Our analysis shows that Populus trichocarpa is the first plant species in which it was observed the complete GS family duplicated. Detailed expression analyses have revealed specific spatial and seasonal patterns of GS expression in

The cereals, including maize (Zea mays), wheat (Triticum aestivum), and rice (Oryza sativa), account for 70% of worldwide food production (http://apps.fao.org; Shewry and Jones, 2005). When such crops are grown for protein content, they require large quantities of nitrogenous fertilizers to attain maximal yields. In the past few years, there has been considerable interest in nitrogen use efficiency, which can be defined as the kernel yield per unit of nitrogen (N) in the soil and the N utilization efficiency, which is the yield per N taken up (Good et al., 2004; Hirel and Lemaire, 2005). A number of physiological and agronomic studies have been undertaken to identify which are the limiting steps in the control of N uptake, assimilation, and recycling during plant growth and development (Jeuffroy et al., 2002; Lawlor, 2002), including cereals such as maize (Hirel et al., 2001, 2005b; Gallais and Hirel, 2004), rice (Yamaya et al., 2002), and wheat (Kichey et al., 2006; Lopes et al., 2006).

Glutamine synthetase (GS) is one of the key enzymes involved in the assimilation of ammonia into organic nitrogen in plants. It is important in legume root nodules where ammonia, produced by the Rhizobium-legume symbiosis, is converted to organic nitrogen before it can be transported to other parts of the plant. In Phaseolus vulgaris three cytosolic and one plastidic GS polypeptide have been identified. One or more of these polypeptides assemble to form distinct octameric GS isoenzymes. GS activity increases significantly in P. vulgaris during nodulation and this is associated with the Increased (or repressed) expression of the three cytosclic polypeptide genes jln-a, gln-β and gln-γ. The temporal and spatial pattern of mRNA and protein distribution of these genes has been investigated using in situ hybridation and immunocytochemistry. An in situ hybridization protocol has been established using photobiotinylated cRNA probes, visualised with alkaline phosphatase, or streptavidin gold with ...

Makennas favorite sport is basketball. She loves soccer too but right now she would choose basketball over soccer. She is excited for camp to start this fall. Its only a week-long but she seems to enjoy it. I think maybe a couple of the other kids will do it too. They have wanted a basketball hoop for a while now and we were just waiting until something came available. Occasionally she would go to our neighbors behind us and play there... they would even play with her sometimes. But the other day someone we know offered theirs to us since they dont use it anymore. So we took them up on it and now we have a basketball hoop. The last few days she has been obsessed with going out to play. And of course the others too but Im sure that will die down soon. She just loves to go out there and shoot hoops! Oh and try some tricks! Maybe we have a basketball star on our hands ...

Growth of cells of Escherichia coli in nitrogen-limited medium induces the formation of glutamine synthetase, product of the glnA gene, and of other proteins that facilitate the assimilation of nitrogen-containing compounds. Transcription from the glnAp2 promoter of the glnALG operon requires the phosphorylation of nitrogen regulator I (NRI) and, for optimal transcription, the binding of NRI-phosphate to two sites that can be over 1,000 base pairs from the binding site for RNA polymerase. In other procaryotic genes, placement of an activator-binding site further upstream from the start site of transcription diminishes expression. To determine how NRI-phosphate activates transcription and why NRI-dependent transcription differs from activation in other systems, we constructed recombinant plasmids with small alterations between the binding sites for NRI-phosphate and RNA polymerase and between the two high-affinity NRI-binding sites. We demonstrate that tightly bound NRI-phosphate activated ...

In cyanobacteria, nitrogen assimilation is a genuine photosynthetic process that requires ATP and reducing equivalents generated in the light. Both nitrate and nitrite are reduced to ammonium in the presence of photosynthetically reduced ferredoxin as the physiological electron donor. Ammonium is incorporated, through the glutamine synthetase-glutamate synthase pathway, into glutamate to yield glutamine by an ATP-dependent ligation reaction catalyzed by glutamine synthetase, and glutamate synthase transfers the amido group of glutamine to 2-oxoglutarate to regenerate glutamate in the presence of reduced ferredoxin. Nitrogen assimilation is tightly regulated in response to environmental cues. Nitrate and nitrite are taken up and reduced only in the absence of ammonium and under CO2 fixation conditions, and the level of glutamine synthetase protein is severely reduced in the presence of ammonium (12).. In the unicellular Synechococcus sp. strain PCC 7942, which does not fix molecular nitrogen, the ...

Abstract: Broccoli (Brassica oleracea L. cv. Hartland) cDNA clone coding the enzyme glutamine synthetase (GS; EC 6.3.1.2.) was isolated from a cDNA library prepared from broccoli head using reverse transcription-polymerase chain reaction (RT-PCR). The partial cDNA clone encodes an mRNA of 695 bp and the derived amino acid sequence is highly homologus to GS from rice cytosol, maize and European grape. GS has a central role in plant nitrogen metabolism and a key enzyme in the assimilation of ammonia. Broccoli head quality deteriorates rapidly after harvest and is associated with an increase in the ammonia content of the floret portions. In order to define the factors contributing to postharvest deterioration of broccoli head, the changes in GS activity and gene expression in the floret and branchlet portions of the broccoli were examined during storage. Northern blot analysis showed that the level of transcript of GS fluctuated in the floret and branchlet portions during storage. Expression of GS ...

Summary: The influence of specific growth rate on the ammonia-assimilating enzymes glutamine synthetase, NADP-linked glutamate synthase and NADP-linked glutamate dehydrogenase was studied in ammonia-limited and glucose-limited chemostat cultures of Erwinia carotovora var. carotovora, E. nigrifluens and E. amylovora. The response of these organisms, representatives of various enzyme groups within the genus Erwinia, showed considerable variation and confirmed the heterogeneity of the genus with respect to ammonia-assimilating enzymes. The overall significance of the glutamine synthetase/glutamate synthase pathway in any organism where the synthesis of these enzymes is not constitutive is questioned.

using the forward primer 5′-TTGACAATTAAT-CATCCGGC-3′ and the specific reverse primers 5′-TGG-TTGTGGTCGACTGGTTTCC-3′ (MtGSII-1a), 5′-AGCGTGGTGTCGACTGGTTTCC-3′ (MtGSII-1b), 5′-AATAGA-TGTCGACTTTCAATGC-3′ (MtGSII-2a) and 5′-AATAGATGTCGACCTTCAATGC-3′ (MtGSII-2b). The same forward primer, which annealed in the vector backbone, was used to amplify the four cDNAs. The reverse primers were designed to specifically abolish the stop codon of each GS cDNA and to include the SalI restriction sequence. The PCR fragments were partially digested with the restriction enzyme NcoI and fully digested with SalI. The PCR digests were cloned into the NcoI and XhoI sites of pET-24-d-T vector, a derivative of pET-24-d(+) (Novagen) containing a C-terminal His tag and a thrombin cleavage site. The resulting plasmids encode C--terminally His6-tagged GS fusion proteins in which the sequence LVPRGSVEHHHHHH follows the GS coding sequences. The four expression constructs were sequenced.. To express the ...

Regulation of GS only occurs in prokaryotes.[24] GS is subject to reversible covalent modification. Tyr397 of all 12 subunits can undergo adenylylation or deadenylylation by adenylyl transferase (AT), a bifunctional regulatory enzyme.[24] Adenylylation is a post-translational modification involving the covalent attachment of AMP to a protein side chain. Each adenylylation requires an ATP and complete inhibition of GS requires 12 ATP. Deadenylylation by AT involves phosphorolytic removal of the Tyr-linked adenylyl groups as ADP. AT activity is influenced by the regulatory protein that is associated with it: PII, a 44-kD trimer.[24] PII also undergoes post-translational modification by uridylyl transferase, thus PII has two forms. The state of PII dictates the activity of adenylyl transferase. If PII is not uridylylated, then it will take on the PIIA form. The AT:PIIA complex will deactivate GS by adenylylation. If PII is uridylylated, then it will take on the PIID form. The AT:PIID complex will ...

1.During infusion of [5-15N]glutamine in patients with gastrointestinal cancer we unexpectedly observed a gradual decrease in time of the appearance rate (Ra) of glutamine in plasma. Here we investigate whether the failure to achieve a plateau isotopic enrichment in plasma is, among other factors, due to incomplete equilibration of the glutamine tracer with the large intramuscular free glutamine pool.. 2.Plasma and intramuscular glutamine enrichment were measured during 6-11 ;h infusions of L-[5-15N]glutamine and L-[1-13C]glutamine in post-absorptive patients admitted to hospital for elective abdominal surgery. L-[1-13C]Leucine and L-[ring-2H5]phenylalanine were infused to measure the proportion of glutamine appearing in plasma directly due to its release from protein.. 3.The glutamine tracer entered muscle, but the rise in intramuscular glutamine enrichment was small, presumably as a result of the enormous size of the intramuscular glutamine pool and the limited speed of entry of glutamine into ...

Glutamine synthetase (GS) catalyzes the recycling of NH4+ with glutamate to form glutamine. Glutamine synthetase is highly expressed in the renal proximal tubule, suggesting ammonia recycling via glutamine synthetase could decrease net ammoniagenesis and thereby limit ammonia available for net acid excretion. This studys purpose was to determine the role of proximal tubule glutamine synthetase in ammonia metabolism under basal conditions and during metabolic acidosis. We generated mice with proximal tubule-specific glutamine synthetase deletion (PT-GS-KO) using Cre-loxP techniques. Under basal conditions, PT-GS-KO increased urinary ammonia excretion significantly. Increased ammonia excretion occurred despite decreased expression of key proteins involved in renal ammonia generation. Following induction of metabolic acidosis the ability to increase ammonia excretion was impaired significantly by PT-GS-KO. The blunted increase in ammonia excretion occurred despite greater expression of multiple ...

The marker enzymes, alanine aminotransferase and glutamine synthetase, verified that enriched periportal and perivenous hepatocytes were isolated from different lobular origin within the rat liver. Our finding that alanine aminotransferase activity was higher in periportal hepatocytes (with a ratio of 1.9 for periportal to perivenous activities, Table 1) was in agreement with histochemical evidence on the enzyme in rat liver (Gorgens et al., 1988) and what was observed in other studies (Sillau et al., 1996; Tosh et al., 1996). The dramatic difference in glutamine synthetase activity between the perivenous and periportal regions (Table 1) was also shown by Stoll et al. (1991) and provided evidence on the successful preparation of enriched populations of periportal and perivenous cells. In addition, glutamate uptake, mediated by the sodium-dependent transporter, System G, in the perivenous region (Stoll et al., 1991) as well as the sodium-independent system in both periportal and perivenous ...

The activity of glutamine synthetase (GS) fromStreptomyces aureofaciens was regulated by the availability of the nitrogen source. Rich nitrogen sources repressed GS synthesis and increased GS adenylylation. The enzyme was purified 270-fold to virtual homogeneity with 37% recovery. The molar mass of the native enzyme and its subunits was determined to be 620 and 55 kDa, respectively, indicating that GS is composed of 12 identical subunits. The enzyme has a hexagonal-bilayered structure as observed by electron microscopy. The isoelectric point of the purified GS was at pH 4.2. The enzyme was stable for 1 h at 50°C but lost activity rapidly when incubated at 65 and 70°C. Mg2+ supported relative synthetic activity of 100 and 72%, respectively, with the corresponding pH optima of 7.3 and 7.0. Mn2+ ions activated transferase activity at a pH optimum of 7.0. The temperature optimum for all GS activities was 50°C. Intermediates of the citric acid cycle exerted insignificant effects on the synthetic

Key metabolic processes and cell signaling in biological systems are mediated by multiple well-regulated enzymatic activities. Dr. Chocks laboratory employed biophysical and chemical methods to elucidate the kinetics and mechanisms of enzyme action and regulation, particularly those mediated by reversible covalent modification of proteins.. Based on detailed studies of the reversible adenylyltion of E. coli glutamine synthetase (GS), Dr. Chock, in collaboration with Dr. E. R. Stadtman, formulated a cyclic cascade model, to reveal the basic principles that underlie this regulatory mechanism and its regulatory advantages in cellular regulation and signal transduction, which include an enormous potential for signal and rate amplification, regulatory sensitivity, and flexibility.. In bacteria, GS links the assimilation of ammonia with diverse biosynthesis and leads to the synthesis of proteins, nucleic acids, complex polysaccharides, and coenzymes. Thus, it is rigorously regulated, including ...

Design, Plasmids, and Gene Assembly. The anti-CEA T84.66/GS18 scFv was composed of the murine VL and the murine VH linked through a glycine-serine-rich, 18-amino acid peptide (2). The scFv was then fused to the hinge, CH2, and CH3 domains of the human IgGγ1 to produce the scFv-Fc fragment ( Fig. 1C).. The T84.66 scFv-Fc (∼1,500 bp) was assembled in pUC18 plasmid (New England Biolabs, Beverly, MA) containing the native mammalian signal sequence. The entire scFv-Fc was excised from the pUC18 vector and ligated into the pEE12 mammalian expression vector (Lonza Biologics, Slough, United Kingdom) incorporating the glutamine synthetase gene (29). The scFv-Fc variants were generated at the pUC18 subcloning stage. Specific mutations were introduced in the CH2 and CH3 domains using a Quick-Change Site Directed Mutagenesis kit (Stratagene, La Jolla, CA) according to manufacturers directions. The plus strand primers were H435R: 5′-GAGGCTCTGCACAACAGGTACACGCAGAAG-3′, H435Q: ...

Alcohol inhibits the production of glutamine once it enters the bloodstream. This in itself is not a bad thing; it is when the body tries to play catch-up that creates fatigue. Glutamine production revs up after the partying is done and the partier is in bed. The bonus glutamine stimulates the brain and keeps it from achieving a deep sleep. The effect of being hopped up on glutamine upon waking is fatigue, often punctuated with tremors, anxiety and feelings of restlessness. This diabolical mix of tiredness and scratchy-eyed irritability is known as glutamine rebound and can also lead to increased blood pressure, nausea and a host of other ailments. Ouch.. Since a glutamine rebound is the result of alcohol preventing the production of glutamine, the only real cure is not drinking alcohol, but lets be realistic; just drinking a bit less than usual will help. The liver processes alcohol at roughly one drink per hour, so if you can manage to drink fewer drinks than hours you have to sleep, you ...

Skeletal muscle contains the greatest intracellular concentration of glutamine, comprising up to 60 percent of total body glutamine stores, and is considered the primary storage depot of glutamine, and thus the primary exporter of glutamine to other tissues [1]. In times of metabolic stress, glutamine is released into circulation, where it is transported to the tissue in need. Intracellular skeletal muscle glutamine concentration is affected by various assaults including injury, sepsis, prolonged stress, and starvation. Besides skeletal muscle, the lungs are the next largest producer of glutamine[9,12 ...

Scientists have discovered an essential mechanism in the spread of cancer. A team led by professor Massimiliano Mazzone (VIB-KU Leuven) and professor Alessandra Castegna (University of Bari) has demonstrated a way to alter the metabolism of macrophages, a particular type of white blood cell often responsible for supporting tumor growth. They found that reducing the glutamine levels of these macrophages changes their behavior: instead of supporting cancer, the macrophages change back into good cells and fight the disease. These groundbreaking findings potentially offer new strategies for immunotherapy. The conclusions of the study are published in the leading scientific journal Cell Reports. ...

In this study, we found that astrocyte release of Glut and D-Asp is supply dependent and that the release of these amino acid GTs can be upregulated chronically by preexposure. We also found that preexposure with an EAAT substrate increased GT release, showing that EAAT substrate specificity is central to the mechanism and illustrating the principle that a false GT can be taken up by astrocytes and released. Using D-Asp, a selective NMDAR agonist, as a false GT, we were able to investigate astrocyte-neuron NMDAR-mediated synchronization in somatosensory cortex, CA1 hippocampus, and VB thalamus.. Astrocytes take up synaptically released Glut via EAATs. This is converted to glutamine by the action of glutamine synthase and cycled back presynaptically, where it is converted to Glut (Hertz et al., 1999). Our findings that exposure of acute brain slices to increased extracellular Glut increases frequency and individual SIC charge recorded in neighboring neurons agree with previous data showing ...

To assist in preventing OTS, consume glutamine both before and after training, and before you go to sleep. Follow the recommended dose (which usually falls between five and ten grams postworkout). Depending on your diet, you may want to consider increasing or decreasing the amount. For a high carbohydrate diet, for example, more glutamine may be appropriate. Glutamine can increase glycogen storage by as much as 16 percent if consumed post-workout.. If you consume glutamine half an hour before working out, you may see noticeable improvements in mass gains.. Side Effects. Although glutamine is not noted for having side effects, people sometimes mention those such as nausea when consuming glutamine in high quantities (above the recommended dose. In short, if you consume glutamine as recommended, you should see no problems.. As with most supplements, the amount of glutamine to take offers no one answer for everyone. Use the above recommendations as a guide and look to your body for feedback. With ...
