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 is the main enzyme used for the enzymatic analysis of GABA (γ-aminobutyric acid).

General description

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

Packaging

10, 25 units in poly bottle

Physical form

Partially purified lyophilized powder containing buffer salts and stabilizer

Unit Definition

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.
