Sigma recommends to dissolve the product with 75 mM phosphate buffer, pH 7.2, containing 25% (v/v) glycerol to a concentration of 2-5 units per mL. Keep the solution in an ice bath while using and store solution frozen. This solution may be stored frozen and thawed several times with only slight loss of activity.

General description
Application
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.[3]
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.
Physical form
Partially purified lyophilized powder containing buffer salts and stabilizer

L-threo-3-Fluoroglutamate and L-erythro-3-fluoroglutamate were tested with glutamate decarboxylase from Escherichia coli. Both isomers were substrates: the threo isomer was decarboxylated into optically active 4-amino-3-fluorobutyrate, whereas the erythro isomer lost the fluorine atom during the reaction, yielding succinic semialdehyde after hydrolysis
