It is suggested that under physiological conditions the transamination pathway is a less favourable route for the oxidation of glutamate (produced by hydrolysis of glutamine) in Ehrlich ascites-tumour cells, and perhaps also kidney, than the glutamate dehydrogenase pathway, as the production of acetyl-CoA strongly inhibits the first mechanism. Glutamine is synthesized from glutamate following the uptake of synaptic glutamate by astrocytes, and glutamine levels have been taken to be a marker of glutamate neurotransmission. However, as with glutamate, glutamine takes part in multiple cell process, which complicates interpretation 158. In microorganisms and plants, glutamine synthetase (also known as GS) has a role in ammonia assimilation in combination with glutamate synthase (glutamine: α-oxoglutarate aminotransferase, or GOGAT) as indicated by the pathway links and pathways ammonia assimilation cycle III and superpathway of ammonia assimilation (plants)).
