The family of glutamate transporters is composed of two primary subclasses: the excitatory amino acid transporter (EAAT) family and vesicular glutamate transporter (VGLUT) family. In the brain, EAATs remove glutamate from the synaptic cleft and extrasynaptic sites via glutamate reuptake into glial cells and neurons , while VGLUTs move glutamate ...
In animals, fungi, and bacteria, GABA-T helps facilitate a reaction that moves an amine group from GABA to 2-oxoglutarate, and a ketone group from 2-oxoglutarate to GABA. [4] [5] [6] This produces succinate semialdehyde and L-glutamate. [4] In plants, pyruvate and glyoxylate can be used in the place of 2-oxoglutarate.
The sodium/glutamate symporter, also known as glutamate permease, is a transmembrane protein family found in bacteria and archaea. These proteins are symporters that are responsible for the sodium-dependent uptake of extracellular glutamate into the cell. They are integral membrane proteins located in the bacterial inner membrane. [1]
Excitatory amino acid transporter 2 (EAAT2) also known as solute carrier family 1 member 2 (SLC1A2) and glutamate transporter 1 (GLT-1) is a protein that in humans is encoded by the SLC1A2 gene. [ 5 ] [ 6 ] Alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known.
Excitatory amino acid transporter 1 (EAAT1) is a protein that, in humans, is encoded by the SLC1A3 gene. [5] EAAT1 is also often called the GLutamate ASpartate Transporter 1 ( GLAST-1 ). EAAT1 is predominantly expressed in the plasma membrane, allowing it to remove glutamate from the extracellular space. [ 6 ]
Gamma-glutamyltransferase (also γ-glutamyltransferase, GGT, gamma-GT, gamma-glutamyl transpeptidase; [1] EC 2.3.2.2) is a transferase (a type of enzyme) that catalyzes the transfer of gamma-glutamyl functional groups from molecules such as glutathione to an acceptor that may be an amino acid, a peptide or water (forming glutamate).
Glutamate racemase performs the additional function of gyrase inhibition, preventing gyrase from binding to DNA. [3] Glutamate racemase (MurI) serves two distinct metabolic functions: primarily, it is a critical enzyme in cell wall biosynthesis, [2] but also plays a role in gyrase inhibition. [3]
In enzymology, a glutamine-pyruvate transaminase (EC 2.6.1.15) is an enzyme that catalyzes the chemical reaction. L-glutamine + pyruvate 2-oxoglutaramate + L-alanine. Thus, the two substrates of this enzyme are L-glutamine and pyruvate, whereas its two products are 2-oxoglutaramate and L-alanine.
