WebGln is synthesized from Glu and ammonia in astrocytes, in a reaction catalyzed by Gln synthetase (GS), which, in the CNS, is almost exclusively located in astrocytes (Martinez-Hernandez et al., 1977). Newly synthesized Gln is transferred to neurons and hydrolyzed by phosphate-activated glutaminase (PAG) to give rise to Glu, a portion of which ... WebIn cells derived from several types of cancer, a transcriptional program drives high consumption of glutamine (Gln), which is used for anaplerosis, leading to a metabolic …

Excessive ammonium assimilation by plastidic glutamine synthetase ...

WebThe products of Gln synthetase-Gln 2-oxoglutarate aminotransferase cycle, Gln, and Glu are highly reactive and are used in various anabolic pathways. Through the action of Asn synthetase (AS; EC 6.3.5.4), Gln will react with Asp to form Asn and Glu. Because all the substrates and products of the AS-catalyzed reaction are major nitrogen carriers... is melting a endothermic
