Glutamine metabolism in the proliferation of GS-expression pituitary tumor cells
Endocrine Connections, 2020 Objective: Many cancer cells cannot survive without exogenous glutamine (Gln); however, cancer cells expressing glutamine synthetase (GS) do not have this restriction.

The intracellular location of nitrogen metabolism enzymes in Pisum arvense L. roots
Acta Societatis Botanicorum Poloniae, 2014 The time course changes of nitrate assimilation enzymes and their distribution has been studied in Pisum arvense roots. The results indicate that nitrate reductase (EC 1.6.6.2) and glutamine synthetase (EC 6.3.1.2) are present in the soluble fraction ...

Glutamine Synthetase and Glutamine Synthetase‐Like Protein from Human Brain [PDF]
Journal of Neurochemistry, 2000 Abstract: Glutamine synthetase (GS; EC 6.3.1.2), a key enzyme ofglutamate metabolism, and another enzyme possessing highhydroxylamine‐L‐glutamine transferase activity comparable to that of GS andtermed GS‐like protein (GSLP) were purified from human brain concurrently.

Proteolytic Inactivation of Glutamine Synthetase in Extracts From Wheat Leaves: Effects of pH, Inorganic Ions and Metabolites [PDF]
, 1994 Glutamine synthetase in extracts from young wheat (Triticum aestivum L.) leaves was quite stable at pH 7.0-9.0, whereas it was remarkably more labile below and above this range.

Abnormalities in Glutamate Metabolism and Excitotoxicity in the Retinal Diseases
Scientifica, 2013 In the physiological condition, glutamate acts as an excitatory neurotransmitter in the retina. However, excessive glutamate can be toxic to retinal neurons by overstimulation of the glutamate receptors.

The Regulation of Glutamine Transport and Glutamine Synthetase in Salmonella typhimurium [PDF]
Journal of General Microbiology, 1976 Transport of glutamine by the high-affinity transport system is regulated by the nitrogen status of the medium. With high concentrations of ammonia, transport is repressed; whereas with Casamino acids, transport is elevated, showing behaviour similar to glutamine synthetase.

Effect of chilling and acclimation on the activity of glutamine synthetase isoforms in maize seedlings [PDF]
Archives of Biological Sciences, 2007 Effects of chilling and acclimation on the activity of cytosolic (GS1) and plastidic (GS2) isoforms of glutamine synthetase (E.C. 6.3.1.2) were studied in chilling-sensitive and acclimation-responsive maize inbred G50.

BMC Evolutionary Biology, 2009 Background Although the gene encoding for glutamine synthetase (glnA) is essential in several organisms, multiple glnA copies have been identified in bacterial genomes such as those of the phylum Actinobacteria, notably the mycobacterial species ...

Glutamine in critical care:current evidence from systematic reviews [PDF]
, 2006 Glutamine, the most abundant amino acid in the body, is thought to become conditionally essential in critical illness. Some of the important roles for glutamine are as a carrier for inter-organ N, a preferred fuel for enterocytes and cells of the immune ...
