Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
Glutamic acid (symbol Glu or E; [4] the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins.It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use.
In enzymology, a glutamate—tRNA ligase (EC 6.1.1.17) is an enzyme that catalyzes the chemical reaction. ATP + L-glutamate + tRNAGlu AMP + diphosphate + L-glutamyl-tRNAGlu. The 3 substrates of this enzyme are ATP, L-glutamate, and tRNA(Glu), whereas its 3 products are AMP, diphosphate, and L-glutamyl-tRNA(Glu).
In biochemistry, the glutamate–glutamine cycle is a cyclic metabolic pathway which maintains an adequate supply of the neurotransmitter glutamate in the central nervous system. [1]
L-glutamate D-glutamate Hence, this enzyme RacE has one substrate , L-glutamate , and one product , D-glutamate. This enzyme belongs to the family of isomerases , specifically those racemases and epimerases acting on amino acids and derivatives, including proline racemase, aspartate racemase, and diaminopimelate epimerase.

L-arogenate + 2-oxoglutarate prephenate + L-glutamate Thus, the two substrates of this enzyme are L-arogenate and 2-oxoglutarate , whereas its two products are prephenate and L-glutamate . However, in most plant species utilizing this enzyme, the left side of the reaction is strongly favored.
Thus, the two substrates of this enzyme are L-glutamate and NAD +, whereas its 4 products are L-glutamine, 2-oxoglutarate, NADH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH 2 group of donors with NAD + or NADP + as acceptor. This enzyme participates in glutamate metabolism and nitrogen ...
The systematic name of this enzyme class is ATP:[L-glutamate:ammonia ligase (ADP-forming)] adenylyltransferase. Other names in common use include glutamine-synthetase adenylyltransferase , ATP:glutamine synthetase adenylyltransferase , and adenosine triphosphate:glutamine synthetase adenylyltransferase .
