Description générale

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.

Qualité

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

Séquence

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).

Autres remarques

Glutamine: fructose-6-phosphate amidotransferase (GFAT) enzymes catalyse the first committed step of the hexosamine biosynthesis pathway (HBP) using glutamine and fructose-6-phosphate to form glucosamine-6-phosphate (GlcN6P). Numerous species (e.g. mouse, rat, zebrafish, chicken) including humans and Drosophila encode two broadly expressed copies
