Isocitrate dehydrogenase kinase/phosphatase
Biochimie, 1989In Escherichia coli, isocitrate dehydrogenase (IDH) is regulated by phosphorylation. This phosphorylation cycle is catalyzed by an unusual, bifunctional protein:IDH kinase/phosphatase. IDH kinase/phosphatase is expressed from a single gene, aceK, and both activities are catalyzed by the same polypeptide.

Isocitrate dehydrogenase of Tetrahymena pyriformis
Molecular and Cellular Biochemistry, 1977We have studied the isocitrate dehydrogenase of Tetrahymena pyriformis. This enzyme is able to utilize both NAD and NADP, but kinetic studies suggest that the enzymatic activity with NAD is not of physiological signifance. Some of the factors that might regualte the NADP-dependent isocitrate dehydrogenase were also studied.

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.

Isocitric Lyase and Isocitric Dehydrogenase in Germinating Lettuce
Physiologia Plantarum, 1968AbstractA soluble isocitric lyase is shown to occur in lettuce seeds. Its activity increases during germination till 72 hours and then falls again. No particulate lyase could be detected. In addition both a soluble and a particulate isocitric dehydrogenase is present in the seeds. Both enzymes react with NAD as well as with NADP.

The estimation of d-isocitric acid in urine using isocitrate dehydrogenase
Clinica Chimica Acta, 1978The amount of D-isocitric acid in urine has been estimated using the enzyme isocitrate dehydrogenase. The technique is rapid and easy to perform. Reproducibility of results was good and results from recovery experiments were excellent. The concentration range for early morning urine samples from normal adults was 0.08-0.65 mmol/l with a mean of 0.29 ...

Mitochondrial Isocitrate Dehydrogenase and Isocitrate Oxidation of Rat Ventral Prostate
Enzyme, 2017Mitochondrial preparations isolated from rat ventral prostate were capable of oxidizing isocitrate by way of NADP isocitrate dehydrogenase (NADP-IDH) and NADIDH. NAD-IDH activity required ADP for activation. The pH responses for NAD-IDH and NADP-IDH were quite different.

An Evaluation of Isocitric Dehydrogenase in Liver Disease
Annals of Internal Medicine, 1961Excerpt Laboratory evaluation of hepatocellular damage has been aided in recent years by the development of new methods for measuring serum activities of enzymes released from injured liver cells.

Isocitrate dehydrogenase kinase can use ATP but not other nucleoside triphosphates as a phosphate donor. It responds hyperbolically to both ATP and isocitrate dehydrogenase. The kinase is inhibited sigmoidally by low concentrations of DL‐isocitrate and hyperbolically by ADP, AMP, NADPH, phosphoenolpyruvate and several other effectors.

The inactivation of isocitrate dehydrogenase by a lipid peroxide
Archives of Biochemistry and Biophysics, 1971Abstract The isocitrate dehydrogenases of rat liver were found extremely sensitive to inacvation by linoleic acid hydroperoxide. Lipid peroxide was much more effective than other peroxides and sulfhydryl reagents tested. Dehydrogenase activity of crude subcellular fractions was more sensitive than the activity of the purified enzyme. The inactivation

Crystallization of NADP-Specific Isocitrate Dehydrogenase
Science, 1973The first crystalline preparation of isocitrate dehydrogenase specific for nicotinamide adenine dinucleotide phosphate has been obtained with enzyme isolated from Escherichia coli . Scanning electron microscopy was employed to elucidate the structure of the crystals, which were found to exist as regular octahedrons ...
