Descripción

General description

Approximately 10 U/mg lyophilizate (120 U/mg enzyme protein) at +25°C with 2-oxoglutarate as the substrate, and ADP as the activator.

GDH (Glutamate dehydrogenase) is a hexamer of 449 residues and is located in the mitochondria. It acts as a branch-point enzyme between amino acid oxidation and urea production. L-glutamate:NAD(P)⁺ oxidoreductase is involved in deamination.

application

Glutamate dehydrogenase has been used to measure residual ammonium by enzymatic analysis during fermentation by wine yeast. It used as a component of cofactor recycling systems for NAD(P) and NAD(P)H.

Quality

Contaminants: <0.005% ADH, LDH, and MDH, each

Sequence

The smallest active structure of GIDH (310,000 to 350,000 ) is a hexamer subunit of 55,400 D. This hexamer reversibly self-assembles forming a polymer with up to eight hexamers (2,200 kD).
