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]
Glutamate transporters are a family of neurotransmitter transporter proteins that move glutamate – the principal excitatory neurotransmitter – across a membrane. The family of glutamate transporters is composed of two primary subclasses: the excitatory amino acid transporter ( EAAT ) family and vesicular glutamate transporter ( VGLUT ) family.
Holins; which function in export of enzymes that digest bacterial cell walls in an early step of cell lysis. Facilitated diffusion occurs in and out of the cell membrane via channels/pores and carriers/porters. Note: Channels: Channels are either in open state or closed state.
The abgT gene is preceded by two genes, abgA and abgB, which code for homologous amino acyl amino hydrolases and hydrolyze p-aminobenzoyl glutamate to p-aminobenzoate and glutamate. [5] Because of the structural similarity of p -aminobenzoyl-glutatmate to peptides, and the enzymatic activities of the abgA and abgB gene products, it has been ...
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 ...
The enzyme, found in bacteria, interacts with an extracytoplasmic substrate binding protein and mediates the import of polar amino acids. This entry comprises bacterial enzymes that import Histidine, Arginine, Lysine, Glutamine, Glutamate, Aspartate, ornithine, octopine and nopaline. [24]
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 (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.
