role of glutamine synthetase and glutamate dehydrogenase in nitrogen . . . However, the discovery of NAD(P)H glutamate synthase in bacteria (Tempest et al , 1970) and later ferredoxin‐dependent glutamate synthase in plants (Lea and Miflin, 1974) established a route, the glutamate synthase cycle, for NH 3 2 to enter into organic compounds via its assimilation by GS
Biosynthesis of Glutamate, Aspartate, Asparagine, - EcoSal Plus Inorganic nitrogen (ammonia) is assimilated into glutamate, which is the major intracellular nitrogen donor Glutamate is a precursor for arginine, glutamine, proline, and the polyamines Glutamate degradation is also important for survival in acidic environments, and changes in glutamate concentration accompany changes in osmolarity
The Role of Glutamine Synthetase (GS) and Glutamate Synthase . . . - MDPI The glutamine synthetase (GS) glutamate synthase (GOGAT) cycle represents a crucial metabolic step of N assimilation, regulating crop yield In this review, the physiological and genetic studies on GS and GOGAT of the main cereal crops will be examined, giving emphasis on their implications in NUE
Glutamine metabolism and optimal immune and CNS function Two principal enzymes regulate intracellular glutamine metabolism Glutamine synthetase (GS; EC 6⋅3⋅1⋅2) catalyses the synthesis of glutamine from glutamate and ammonia in glutamine synthesising cells and tissues, while phosphate-dependent glutaminase (GLS; EC 3⋅5⋅1⋅2) catalyses the hydrolysis of glutamine to glutamate (with the
Glutamine, Glutamate, Aspartate, and Asparagine are Central Regulators . . . Ammonium ion, derived either from nitrogen assimilation or from photorespiration, is incorporated into glutamine by a reaction catalyzed by glutamine synthase (GS), and glutamine is further converted into glutamate catalyzed by glutamate synthase (GOGAT) (Fig 3 1)
Nitrogen Assimilation and Dissimilation | SpringerLink Glutamate and Glutamine Biosynthesis—Glutamate is the first amino acid to be synthesized by reductive amination of α-ketoglutarate by glutamate dehydrogenase during growth of bacterium on inorganic ammonium compounds
Glutamine Synthetase: Diverse Regulation and . . . - ACS Publications ABSTRACT: Glutamine synthetase (GS) is a ubiquitous enzyme central to nitrogen metabolism, catalyzing the ATP-dependent formation of glutamine from glutamate and ammonia Positioned at the intersection of nitrogen sophisticated regulation
Glutamine Metabolism, Sensing and Signaling in Plants Glutamine (Gln) is the first amino acid synthesized in nitrogen (N) assimilation in plants Gln synthetase (GS), converting glutamate (Glu) and NH 4+ into Gln at the expense of ATP, is one of the oldest enzymes in all life domains
Nitrogen Metabolism- How does Nitrogen Enter the Biomass, and form . . . Ammonia incorporation in animals occurs through the actions of glutamate dehydrogenase and glutamine synthetase Glutamate plays the central role in mammalian nitrogen flow, serving as both a nitrogen donor and nitrogen acceptor
