L-glutamic dehydrogenase catalyzes the conversion of glutamate to α-ketoglutarate.
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.

Definición de unidad

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.

Glutamate dehydrogenase (GDH) catalyzes the reversible inter-conversion of glutamate to α-ketoglutarate and ammonia. High levels of GDH activity is found in mammalian liver, kidney, brain, and pancreas. In the liver, GDH reaction appears to be close-to-equilibrium, providing the appropriate ratio

Enzymes produced by halophilic archaea are generally heat resistant and organic solvent tolerant, and accordingly important for biocatalytic applications in 'green chemistry', frequently requiring a low-water environment. NAD(+)-dependent glutamate dehydrogenase from an extremely halophilic archaeon Halobacterium salinarum strain NRC-36014 was
