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 ...

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.
