GLUTAMATE CARBOXY LYASE Meaning and
Definition
-
Glutamate Carboxy Lyase (GLC) is an enzyme that plays a crucial role in the metabolism of glutamate, a non-essential amino acid. It catalyzes the reversible decarboxylation of L-glutamate to form γ-aminobutyric acid (GABA) and carbon dioxide. This reaction is the first and rate-limiting step in the GABA shunt pathway.
GLC is primarily found in certain bacteria, such as Escherichia coli, where it is encoded by the gadB gene. It is also present in some plants and mammals, albeit with different functions. In bacteria, GLC is part of the glutamate-dependent acid resistance system, which helps these organisms survive in acidic environments by converting excess glutamate into GABA, reducing intracellular pH. In plants, GLC has been implicated in seed dormancy and germination, as well as in stress responses.
The enzymatic activity of GLC involves the binding of glutamate to the active site of the enzyme, followed by the release of the carboxyl group, resulting in the formation of GABA. GLC utilizes pyridoxal phosphate (PLP) as a cofactor, which participates in the decarboxylation process by forming a Schiff base with the amino acid substrate.
The study of GLC and its regulation is of great interest in various fields, including biochemistry, microbiology, and plant biology, as it provides insights into the roles of GABA and glutamate metabolism in different organisms.
