IT has previously1,2 been reported that there is an enzymatic cycle of inorganic nitrogen. In the present work, we have demonstrated that the dehydrogenating system in the cyclic processes can be separated from the reducing one, and that each dehydrogenase behaves specifically towards different inhibitors.

Analysis of Cell Viability by the Lactate Dehydrogenase Assay.
Cold Spring Harbor Protocols, 2018A common method for determining cytotoxicity is based on measuring the activity of cytoplasmic enzymes released by damaged cells. Lactate dehydrogenase (LDH) is a stable cytoplasmic enzyme that is found in all cells. LDH is rapidly released into the cell

Stability of dehydrogenases III. malate dehydrogenases
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982Cytoplasmic and mitochondrial malate dehydrogenases from pig and chicken were studied by chemical modification of amino groups, hybridization of immobilization. Determination of thermal stability was used to characterize the different species. Modification of amino groups was found to decrease thermal stability especially when neutralization of the ...

Glutamate dehydrogenase-malate dehydrogenase complex
Archives of Biochemistry and Biophysics, 1979Abstract Kinetic and Sephadex gel filtration epxeriments indicate that in the presence of palmitoyl-CoA, glutamate dehydrogenase forms a complex with mitochondrial malate dehydrogenase. In this complex, palmitoyl-CoA is bound to glutamate dehydrogenase but is not bound to malate dehydrogenase.

The kinetics of furfural inhibition of the enzymes alcohol dehydrogenase (ADH; EC 1.1.1.1), aldehyde dehydrogenase (AlDH; EC 1.2.1.5) and the pyruvate dehydrogenase (PDH) complex were studied in vitro. At a concentration of less than 2mM furfural was found to decrease the activity of both PDH and AlDH by more than 90%, whereas the ADH activity ...

Succinate dehydrogenase (SDH)‐deficient neoplasia
Histopathology, 2018The succinate dehydrogenase (SDH) complex is a key respiratory enzyme composed of four subunits: SDHA, SDHB, SDHC and SDHD. Remarkably, immunohistochemistry for SDHB becomes negative whenever there is bi‐alleic inactivation of any component of SDH, which

Favism and Glucose-6-Phosphate Dehydrogenase Deficiency.
New England Journal of Medicine, 2018Favism and Glucose-6-Phosphate Dehydrogenase Deficiency When persons with G6PD deficiency eat fava beans, acute hemolytic anemia may develop. It is caused by the generation of free radicals from the metabolism of glucosides in the beans.

Serum isocitric dehydrogenase and glutamic dehydrogenase in schistosomiasis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1969Abstract 19 patients with schistosomiasis were studied for serum ICDH and GLDH activities; they were divided into two groups according to the presence or absence of hepatic involvement. Serum ICDH levels were normal, except in one patient with advanced hepatic decompensation.
