General description

Glutamate is a non-essential amino acid. It acts as a primary excitatory neurotransmitter. In major trauma, major surgery, sepsis and bone marrow transplantation, glutamate functions as an essential amino acid.

Application

L-Glutamate Oxidase from Streptomyces sp has been used to determine the enzyme activity of the immobilized glutamate oxidase (GOx). It has also been used as a component of imaging buffer for stochastic optical reconstruction microscopy (STORM) imaging.

Biochem/physiol Actions

L-glutamate oxidase catalyzes the conversion of L-glutamate to 2-oxoglutarate.
Major enzyme in the synthesis or degradation of glutamic acid; transfers an amine to α-ketoglutaric acid to form L-glutamic acid or deamidates L-glutamic acid

Unit Definition

One unit will form 1.0 μmole of α-ketoglutaric acid from L-glutamic acid per min at pH 7.4 at 30 °C.

The apparent Michaelis constant, K(M), for glutamate oxidase (GluOx) immobilised on Pt electrodes increased systematically with enzyme loading. The effect was due, at least in part, to electrostatic repulsion between neighbouring oxidase molecules and the anionic substrate, glutamate (Glu). This
