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 ...
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]
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 basic fold of the MFS transporter is built around 12, [4] or in some cases, 14 transmembrane helices [5] (TMH), with two 6- (or 7- ) helix bundles formed by the N and C terminal homologous domains [6] of the transporter which are connected by an extended cytoplasmic loop. The two halves of the protein pack against each other in a clam-shell ...
There are several families that function in amino acid transport, some of these include: TC# 2.A.3 - Amino Acid-Polyamine-Organocation (APC) Superfamily; TC# 2.A.18 - Amino Acid/Auxin Permease (AAAP) Family
For example, SLC1A1 is the first isoform of subfamily A of SLC family 1. An exception occurs with SLC family 21 [ 5 ] (the organic anion transporting polypeptide transporters), which for historical reasons have names in the format SLCOnXm where n = family number, X = subfamily letter, and m = member number.
Glutamate racemase (MurI) provides multiple functions for bacterial cells. MurI is an enzyme which is primarily known for its role in synthesizing bacterial cell walls. While performing the function of cell wall synthesis, MurI also acts as a gyrase inhibitor, preventing gyrase from binding to DNA.
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).
