D-2-Hydroxyglutarate Dehydrogenase (D2HGDH) from Acidaminococcus fermentans

D-2-Hydroxyglutarate Dehydrogenase (D2HGDH) is a member of the D-2-hydroxyacid NAD⁺ dependent dehydrogenase family of proteins. D2HGDH catalyzes the conversion of α-ketoglutarate (α--KG) to D-2-hydroxyglutarate (D2HG), coupled to the oxidation of NADH to NAD⁺ .

The crystal structure of D2HGDH from Acidaminococcus fermentans has been reported. D2HGDH from Acidaminococcus fermentans has been used in several enzymatic assays, such as:

• A continuous spectrophotometric assay to measure the activity of aminotransferases, based on the transamination of a keto compound and L-glutamate, which yields a corresponding amino compound and 2-oxoglutarate.
• Determination of D2HG levels in biological fluids such as serum, urine, cell culture supernatants, and cell or tissue lysates.
• A coupled assay system to measure branched-chain amino acid aminotransferase activity.

This recombinant D2HGDH product is supplied as an aqueous solution in 20 mM Trizma^® buffer, pH 7.5, with 150 mM NaCl, and 10% glycerol.

One unit of enzyme oxidizes 1 μmole of NADH to NAD⁺ coupled to the reduction of α-ketoglutarate to (D)-2-hydroxyglutarate per minute at 37°C at pH 8.0.
