10232056-16	1999	These results suggest that since no dramatic changes in the levels of protein were observed in the muscle and liver, there is an alteration in glutaminase and glutamine synthetase activity in order to maintain nitrogen metabolism in the initial phase of hypoxic exposure.	Nitrogen	210-218	glutamate-ammonia ligase	Rattus norvegicus	159-179	
15481771-10	1997	Furthermore, total nitrogen remained unchanged in these animals and they showed an increased activity in alanine aminotransferase and glutamine synthetase.	Nitrogen	19-27	glutamate-ammonia ligase	Rattus norvegicus	134-154	
8866724-1	1996	Exposing 7-day-old rat pups to hypoxia, 8% oxygen/92% nitrogen, for 3 h alters glutamate (GLU), glutamine and glutamine synthetase (GS) activity in the striatum, frontal cortex and hippocampus.	Nitrogen	54-62	glutamate-ammonia ligase	Rattus norvegicus	110-130	
6138251-6	1983	This rather peculiar localization of glutamine synthetase demonstrates an interesting aspect of liver zonation and might have important implications for liver glutamine and, more generally, nitrogen metabolism.	Nitrogen	190-198	glutamate-ammonia ligase	Rattus norvegicus	37-57	
10429966-6	1999	Detoxification of ammonia by glutamine synthetase may be limited due to a shortage of glutamate when the nitrogen load is high.	Nitrogen	105-113	glutamate-ammonia ligase	Rattus norvegicus	29-49
