Role of isocitrate dehydrogenase in glioma
Expert Review of Neurotherapeutics, 2011Recently, the isocitrate dehydrogenase (IDH) enzymes have become a focal point for research aimed at understanding the biology of glioma and identifying novel targets for therapy. Following the publication of a landmark genetic sequencing study in 2008, which identified IDH1 as a frequently mutated gene in glioblastoma, much work has been carried out ...

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.

The isocitrate dehydrogenase from cyanobacteria
Archives of Microbiology, 1983The present communication describes the properties of isocitrate dehydrogenase in crude extracts from the unicellular Anacystis nidulans and from heterocysts and vegetative cells of Nostoc muscorum and Anabaena cylindrica. The activity levels of this enzyme are much higher in heterocysts than in vegetative cells of N. muscorum and A.

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.

The regulatory properties of isocitrate dehydrogenase kinase and isocitrate dehydrogenase phosphatase from Escherichia coli ML308 and the roles of these activities in the control of isocitrate dehydrogenase [PDF]
European Journal of Biochemistry, 1984 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.

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 ...
