Merck, G7509-25UN, GABase from Pseudomonas fluorescens

General description
Research area: Neuroscience

GABase is a commercially available mixture composed of γ-aminobutyric acid aminotransferase (GABGT) and succinic semialdehyde dehydrogenase (SSDH) obtained from Pseudomonas fluorescens.
Application
GABase from Pseudomonas fluorescens has been used for GABase assay to quantify the extracellular and intracellular concentration of GABA (γ-aminobutyric acid).
Biochem/physiol Actions
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.
Physical form
Partially purified lyophilized powder containing buffer salts and stabilizer
Other Notes
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.
