Merck, G7882-1G, L-Glutamic Dehydrogenase from bovine liver

Application
L-Glutamic Dehydrogenase was used to catalyzes the conversion of isocitrate into a-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:
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.
Packaging
Package size based on protein content
Physical form
Contains citrate and potassium phoshate buffer salts.
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.
