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).
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 ...
Animal glutamate cysteine ligase (GCL) is a heterodimeric enzyme composed of two protein subunits that are coded by independent genes located on separate chromosomes: Glutamate cysteine ligase catalytic subunit (GCLC, ~73 kDa) possesses all of substrate and cofactor binding sites and is responsible for all of the catalysis.
Theanine / ˈ θ iː ən iː n /, commonly known as L-theanine and sometimes L-gamma-glutamylethylamide or N 5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine. It is produced by certain plants such as Camellia sinensis (the tea plant), and by some fungi.
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 ...
In enzymology, a glutamin-(asparagin-)ase (EC 3.5.1.38) is an enzyme that catalyzes the chemical reaction. L-glutamine + H 2 O L-glutamate + NH 3. Thus, the two substrates of this enzyme are L-glutamine and H 2 O, whereas its two products are L-glutamate and NH 3.
The two products are succinate semialdehyde and L-glutamate. This enzyme belongs to the family of transferases , specifically the transaminases , which transfer nitrogenous groups. The systematic name of this enzyme class is 4-aminobutanoate:2-oxoglutarate aminotransferase .
