General description

Glutamic acid is an amino acid with an acidic side group. It works as a proton donor. Decarboxylation of glutamic acid results in the formation of GABA (γ aminobutyric acid), a potent neurotransmitter. Isotope labeled amino acids are required for the production of isotopically labeled proteins.

Glutamylation, introduced by tubulin tyrosine ligase-like (TTLL) enzymes, is the most abundant modification of brain tubulin. Essential effector proteins read the tubulin glutamylation pattern, and its misregulation causes neurodegeneration. TTLL glutamylases post-translationally add glutamates to internal glutamates in tubulin carboxy-terminal

The brain consists of various areas with anatomical features. Neurons communicate with one another via excitatory or inhibitory synaptic transmission. Altered abundance of neurotransmitters, including glutamate and gamma-aminobutyric acid (GABA), in specific brain regions is closely involved in severe neurological
