GABase is a commercially available mixture composed of γ-aminobutyric acid aminotransferase (GABGT) and succinic semialdehyde dehydrogenase (SSDH) obtained from Pseudomonas fluorescens.

애플리케이션

GABase from Pseudomonas fluorescens has been used for GABase assay to quantify the extracellular and intracellular concentration of GABA (γ-aminobutyric acid).

생화학적/생리학적 작용

GABase catalyzes the conversion of γ-aminobutyric acid (GABA) to succinic acid in the central nervous system. It is used to measure GABA levels in various biological samples. p-Hydroxybenzaldehyde (HBA) is known to be a potential inhibitor on GABase.

단위 정의

One unit will convert 1.0 μmole of γ-aminobutyric acid (GABA) to succinic semialdehyde and then to succinate per min with a stoichiometric reduction of 1.0 μmole of NADP+ at pH 8.6 at 25 °C.

Many studies have focussed on modulating the activity of γ-aminobutyric acid transaminase (GABA-T), a GABA-catabolizing enzyme, for treating neurological diseases, such as epilepsy and drug addiction. Nevertheless, human GABA-T synthesis and purification have not been established. Thus, biochemical and drug

It is well established that the glutamate decarboxylase (GAD) system is central to the survival of Listeria monocytogenes at low pH, both in acidic foods and within the mammalian stomach. The accepted model proposes that under acidic conditions extracellular glutamate

Glutamate (GLU) and gamma-aminobutyric acid (GABA) are neurotransmitters (NTs) with an essential role in signal transmission in the brain. Brain disorders, such as epilepsy, Alzheimer's and Parkinson's diseases, and traumatic brain injury can be linked to imbalances in the GLU-GABA

Imbalances in levels of glutamate (GLU) and gamma-aminobutyric acid (GABA) and their sub-second signaling dynamics occur in several brain disorders including traumatic brain injury, epilepsy, and Alzheimer's disease. The present work reports on the optimization and in vivo testing of
