The Role of Glutamine Synthetase (GS) and Glutamate Synthase (GOGAT) in the Improvement of Nitrogen Use Efficiency in Cereals [PDF]
Biomolecules, 2023 Cereals are the most broadly produced crops and represent the primary source of food worldwide. Nitrogen (N) is a critical mineral nutrient for plant growth and high yield, and the quality of cereal crops greatly depends on a suitable N supply.

Early care of N-acetyl glutamate synthase (NAGS) deficiency in three infants from an inbred family [PDF]
Molecular Genetics and Metabolism Reports, 2020 N-acetyl glutamate synthase (NAGS) deficiency is the rarest urea cycle defect presenting as neonatal onset life-threatening hyperammonemia. We report here a family history of severe NAGS deficiency: after the index-case with severe hyperammonemia, one ...

gltB encoding glutamate synthase is involved in persister and biofilm formation and virulence in Staphylococcus aureus [PDF]
Microbiology SpectrumGlutamate metabolism plays a pivotal role in linking the tricarboxylic acid cycle, arginine biosynthesis, and purine metabolism, and these pathways have been shown to be involved in persister formation.

Ametryn and Clomazone Disrupt Mitochondrial Bioenergetics in Rat Liver: Evidence for Inhibition of Complexes I and II and ATP Synthase [PDF]
ToxicsAmetryn (AMT) and clomazone (CLZ) are commonly used herbicides frequently detected in food and water, raising concerns about potential health risks. This study investigated whether AMT and CLZ impair mitochondrial bioenergetics, a key mechanism linked to

Differential regulation of GS-GOGAT gene expression by plant growth regulators in Arabidopsis seedlings [PDF]
Archives of Biological Sciences, 2016 Primary and secondary ammonium assimilation is catalyzed by the glutamine synthetase-glutamate synthase (GS-GOGAT) pathway in plants. The Arabidopsis genome contains five cytosolic GS1 genes (GLN1;1 - GLN1;5), one nuclear gene for chloroplastic ...

Glutamate Synthase from Rice Leaves [PDF]
Plant Physiology, 1982 Ferredoxin-dependent glutamate synthase (EC 1.4.7.1) from rice leaves (Oryza sativa L. cv Delta) was purified 206-fold with a final specific activity of 35.9 mumoles glutamate formed per min per milligram protein by a procedure including ammonium sulfate fractionation, DEAE-cellulose chromatography, Sephacryl S-300 gel filtration, and ferredoxin ...

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 ...
