Application
L-glutamic dehydrogenase was used to catalyze the conversion of isocitrate into α-ketoglutarate and carbon dioxide.
Biochem/physiol Actions
Mammalian forms of this enzyme, including this bovine form, can use either NADP(H) or NAD(H) as coenzymes. L-glutamic dehydrogenase plays a unique role in mammalian metabolism. The reverse reaction catalyzed by this enzyme is the only pathway by which ammonia can become bound to the α-carbon atom of an α-carboxylic acid and thus, is the only source of de novo amino acid synthesis in mammalian species.
The bovine enzyme is characterized by three sets of properties:
L-glutamic dehydrogenase catalyzes the conversion of glutamate to α-ketoglutarate.
The bovine enzyme is characterized by three sets of properties:
- It has a reversible concentration-dependent association, producing higher molecular weight forms.
- Forms tight enzyme-reduced coenzyme-substrate ternary complexes whose rates of dissociation modulate the steady-state reaction rates.
- Exhibits a wide variety of effects from the binding of any of a number of nucleotide modifiers.
L-glutamic dehydrogenase catalyzes the conversion of glutamate to α-ketoglutarate.
Physical form
50% glycerol solution
Analysis Note
Protein determined by biuret.
Other Notes
One unit will reduce 1.0 μmole of α-ketoglutarate to L-glutamate per min at pH 7.3 at 25 °C, in the presence of ammonium ions.

Astrocytes have a prominent role in metabolic homeostasis of the brain and can signal to adjacent neurons by releasing glutamate via a process of regulated exocytosis. Astrocytes synthesize glutamate de novo owing to the pyruvate entry to the citric/tricarboxylic acid

The mechanisms of HIV-1 neurotoxicity remain still undefined although the induction of signalling events and a modest inhibition of glutamate uptake induced by the envelope glycoprotein, gp120, have called attention to astrocytes. Here we demonstrate that the levels at which
