Formation of Glutamine and Activities of Glutamine Synthetase in Goats
The Japanese Journal of Veterinary Science, 1977 When goats were administered orally with urea in a dose of 0.3 g per kg of body weight, the blood concentration of glutamine-N in the jugular vein increased to about 6μg per ml of plasma, reflecting the removal of ammonia by forming glutamine in the animal body. The blood glutamine seemed to undergo a more rapid turnover than the blood urea.

Bone Research, 2022 Ammonia plays an important role in cellular metabolism. However, ammonia is considered a toxic product. In bone marrow-derived mesenchymal stem cells, multipotent stem cells with high expression of glutamine synthetase (GS) in bone marrow, ammonia and ...

Glutamine synthetase activity during embryonic and larval development of the silkworm Bombyx mori L. and role of a JH analogue [PDF]
, 1992 Silkworm eggs of diapause nature were chilled or treated with hydrochloric acid. Glutamine synthetase activity in such treated eggs was present soon after the treatment, whereas in non-diapause eggs it was not detectable until 24 h after the start of ...

Glutamine synthetase in muscle and kidney [PDF]
Biochemical Journal, 1970 1. Glutamine synthetase activity has been determined in extracts of rat cardiac and skeletal muscle and kidney, after treatment to ensure that the rate of synthesis was proportional to time of incubation and to amount of extract added. The activity was measured by two methods, with hydroxylamine as substrate. 2.

Transgenic expression of plastidic glutamine synthetase increases nitrogen uptake and yield in wheat
Plant Biotechnology Journal, 2018 Summary The plastidic glutamine synthetase isoform (GS2) plays a key role in nitrogen (N) assimilation. We introduced TaGS2‐2Abpro::TaGS2‐2Ab, the favourable allele of TaGS2‐2A in the winter wheat (Triticum aestivum) variety Ji5265. Transgenic expression

Glutamine synthetase is necessary for sarcoma adaptation to glutamine deprivation and tumor growth
Oncogenesis, 2019 Despite a growing body of knowledge about the genomic landscape and molecular pathogenesis of sarcomas, translation of basic discoveries into targeted therapies and significant clinical gains has remained elusive.

Expression of Glutamine Synthetase in Macrophages [PDF]
Journal of Histochemistry & Cytochemistry, 2000 We studied the expression of glutamine synthetase in liver macrophages (Kupffer cells, KCs) in situ and in culture. Glutamine synthetase was detectable at the mRNA and protein level in freshly isolated and short-term-cultured rat liver macrophages. Enzyme activity and protein content were about 9% of that in liver parenchymal cells.

Glutamine versus ammonia utilization in the NAD synthetase family. [PDF]
PLoS ONE, 2012 NAD is a ubiquitous and essential metabolic redox cofactor which also functions as a substrate in certain regulatory pathways. The last step of NAD synthesis is the ATP-dependent amidation of deamido-NAD by NAD synthetase (NADS).
