生物活性/药理作用

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 bolism. 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.

样品准备说明

This product is supplied as a suspension in 2.0 M ammonium sulfate, pH 7.0. This solution is then diluted to 0.3 - 0.6 units/ml using triethanolamine buffer, pH 7.3, for use in enzymatic assays.

有效单位定义

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.
