Glutamate Dehydrogenase, a Complex Enzyme at a Crucial
Webglutamate dehydrogenase (an enzyme that can convert glutamate to α- Ketoglutarate and vice versa). lactate dehydrogenase (used to convert NADH back to NAD + in anaerobic glycolysis, and in the back reaction to produce NADH) pyruvate dehydrogenase (A common enzyme that feeds the TCA Cycle by converting pyruvate to acetyl CoA, using … WebGlutamate dehydrogenase and glutamine synthetase (GS) enzyme activities were measured on mycelia grown under various nitrogen (N) conditions. The contribution of GDH in ammonium assimilation was further estimated by following 15N incorporation from (15NH4)2SO4 into glutamate, when GS was inhibited by phosphinothricin. Glutamate dehydrogenase (GLDH, GDH) is an enzyme observed in both prokaryotes and eukaryotic mitochondria. The aforementioned reaction also yields ammonia, which in eukaryotes is canonically processed as a substrate in the urea cycle. Typically, the α-ketoglutarate to glutamate reaction does not occur in … See more GLDH can be measured in a medical laboratory to evaluate the liver function.
