In peripheral tissues once ammonia and glutamate combine to form glutamine through the action of the glutamine synthetase
enzyme, the glutamine is exported from the tissue and transported through the blood to the liver where the free ammonia is released through the action of the glutaminase enzyme.
The results of our research showed that the increase of nitrogen fertilizers dose did not lead to the increase of activity of glutamine synthetase
. Thus, the introduction of 2/3 of the calculated nitrogen norm in the tillering period suppressed enzyme's activity a little--0.5 unit/mg of protein, whereas 1/3 of nitrogen increased the activity of glutamine synthetase
up to 0.8 unit/mg of protein.

Inhibition of nitrogen-fixing activity of cianobiont affects the localization of glutamine synthetase
in hair cells of Azolla.
Its assimilation is then enabled by the coupled action of the enzymes glutamate synthetase (glutamine: 2 oxoglutarate amido-transferase [GOGAT]) and glutamine synthetase
(GS) (Ka-meya et al, 2006, 2007).
Previous studies have demonstrated that oxidative processes often result in changes of the activities of key enzymes, including glutamine synthetase
(GS), creatine kinase (CK) and tyrosine hydroxylase (Hensley et al., 1995).
Sequence analysis of the chloroplast glutamine synthetase
gene, a single-copy nuclear gene, was used to infer relationship between the Rhodiola species.
United States Patent 7,070,945, "Process for determining the presence of monomeric brain associated human glutamine synthetase
in patients exhibiting mild cognitive impairment," claims a method for determining those patients suffering from mild cognitive impairment who have a likelihood of progressing to Alzheimers disease.
The only way to eliminate any ammonia that has reached the brain cells is through a reaction mediated by an enzyme called glutamine synthetase
, which combines a molecule of the amino acid glutamate with a molecule of ammonia to form the amino acid glutamine.
