An investigation of the pathway of nitrogen incorporation into the leaf and root metabolism of Helianthus annuus L
… pools after methionine sulphoximine treatment. Glutamate dehydrogenase activity (NADH-dependent) was not inhibited by the methionine sulphoximine pretreatment. Assimilation of newly reduced nitrogen into amino compounds in Helianthus leaves via the glutamine synthetase/ glutamate synthase …

A Mutant of Arabidopsis Thaliana Deficient in Chloroplast Dicarboxylate Transport Activity
… for a supply of substrates were assayed. Glutamate synthase and glutamate-oxaloacetate aminotransferase were assayed on intact chloroplasts and found missing in the mutant. Transport activity was also measured directly using the silicone oil filter centrifugation technique. Malate, …

Genetic Analysis of Nitrogen Remobilization and Kernel Compositon in Zea Mays L. and Sorghum Bicolor (L.) Moench
… composition analysis suggest a role for NADH - Glutamate Synthase as a sink control of N remobilization from the leaves. Genes identified in these analyses suggest that genetic controls at both the source and sink level affect the timing and rate of N remobilization from the leaves. Knowledge of …

Synthesis of furo[2,3-d]pyrimidines, thieno[2,3- d]pyrimidines, pyrrolo[2,3-d]pyrimidines as classical and nonclassical antifolates, receptor tyrosine kinase (RTK) inhibitors and antimitotic agents
… mitotic agents has been discussed. Thymidylate synthase (TS), dihydrofolate reductase (DHFR) and glycinamide ribonucleotide formyltransferase (GARFTase) are important folate dependent enzymes that are targets for cancer chemotherapy and the treatment of infectious diseases. Classical …

Analysis of the ammonium assimilation pathways of the human colonic bacterium, bacteroides thetaiotaomicron
… ammonium through the two primary pathways, the glutamate dehydrogenase (GDH) pathway and the glutamine synthetase/glutamate synthase (GS/GOGAT) pathway. To gain insight into the genomic features underlying ammonium uptake and assimilation in this bacterium, comparative transcriptomic analysis …

Transcriptional effects of predator cues in the brain of Spodoptera frugiperda (lepidoptera: noctuidae) moths exposed to bat ultrasound
… in cellular processes in the brain, including glutamate production and metabolism, ionotropic sensory receptor expression, mitochondrial metabolism, actin cytoskeleton dynamics, chromatin binding and other epigenetic modifications, axonal guidance and remodeling, cilia function and development, …

Molecular-genetic characterisation of arginine auxotrophy in the opportunistic human pathogen, Pseudomonas aeruginosa
… peptides derived from the enzyme, N-acetyl glutamate synthase (NAGS) encoded by argA. This was unexpected because the argA gene in AMB128 was disrupted by a Tn insertion (and this insertion was confirmed by inspection of the whole genome sequence). This up-regulation was found to be likely …

Effects of Nitrate and Cytokinin on Nitrogen Metabolism and Heat Stress Tolerance of Creeping Bentgrass
… glutamine synthetase (GS2), ferredoxin-dependent glutamate synthase (Fd-GOGAT), and glutamate dehydrogenase (GDH) and N metabolites in shoots were monitored during the day/night cycle (14/8 h). All the measured parameters exhibited clear diurnal changes, except GS2 expression and total protein. …

Assessment of potential antibacterial drug targets
… protease subunit P (ClpP), and the dihydrofolate synthase:folyl-poly-glutamate synthase (bifunctional protein FolC). X-ray crystallography was used to determine protein structures of KynB, Ddl and ClpP from various bacteria. Additionally, different enzymatic and binding assays were applied to …

Regulation and characterization of the nitrogen assimilatory gene cluster in Clostridium acetobutylicum P262
… the locus encoding the structural genes for the glutamate synthase (GOGAT) enzyme; and to detennine the mechanisms and growth conditions which regulate the activity of these two key enzymes of nitrogen assimilation. In addition, we were interested in characterizing clone pMET13Cl, which was …

Sulfite reductase and thioredoxin in oxidative stress responses of methanogenic archaea
… enzymes, namely F420H2-dependent glutamate synthase and assimilatory sulfite reductase. Another aspect of my research concerns the reactivation of proteins that are deactivated by the entry of oxygen inside the cell. Here I focused specifically on the role of thioredoxin (Trx) in …

Genetic and biochemical analysis of nitrogen metabolism in ruminal anaerobic bacteria: a comparison between ruminococcus albus 8 and prevotella ruminicola 23
… on ammonia or urea led to the synthesis of glutamate from ammonia by the NADPH-dependent glutamate dehydrogenase (NADPH-GDH). This glutamate was then transformed to glutamine by glutamine synthetase (GS). The later transformation was especially evident during early log phase, while the …
