16663852-6	1984	On inhibiting glutamine synthetase using MSX, (15)N enrichment of glutamate, alanine, aspartate, and ornithine continued although labeling of glutamine was quite low.	Ornithine	101-110	glutamate-ammonia ligase	Homo sapiens	14-34	
30706424-2	2019	L-ornithine serves as an intermediary in the urea cycle in periportal hepatocytes in the liver and as an activator of carbamoyl phosphate synthetase, and, like L-aspartate, by transamination to glutamate via glutamine synthetase in perivenous hepatocytes as well as by skeletal muscle and brain.
