Aplicação

Isocitric dehydrogenase (IDH) has been used:
  • for in vitro activity assay to study the effects of thorium on citric acid cycle enzymes in the mitochondrial respiration pathway
  • as a standard to measure the impact of temperature on nicotinamide diphosphate (NADP)-IDH activity
  • in isocitrate assay

Ações bioquímicas/fisiológicas

Isocitrate dehydrogenase (IDH) is a homodimeric enzyme and participates in several processes such as adapting to hypoxia, histone demethylation, and DNA modification. This enzyme has three isoforms like IDH1, IDH2, and IDH3.

Definição da unidade

One unit will convert 1.0 μmole of isocitrate to α-ketoglutarate per min at pH 7.4 at 37 °C.

Intracellular iron levels are strictly regulated to support homeostasis and avoid iron-mediated ROS production. Loss of iron-sulfur cluster (ISC) synthesis can increase iron loading and promote cell death by ferroptosis. Iron-responsive element-binding proteins IRP1 and IRP2 posttranscriptionally regulate iron homeostasis.

Alterations to genes involved in cellular metabolism and epigenetic regulation are implicated in the pathogenesis of myeloid malignancies. Recurring mutations in isocitrate dehydrogenase (IDH) genes are detected in approximately 20% of adult patients with acute myeloid leukemia (AML) and 5%

Transhydrogenase couples the reduction of NADP+ by NADH to inward proton translocation across mitochondrial and bacterial membranes. The coupling reactions occur within the protein by long distance conformational changes. In intact transhydrogenase and in complexes formed from the isolated, nucleotide-binding

Many cancer cells follow an aberrant metabolic program to maintain energy for rapid cell proliferation. Metabolic reprogramming often involves the upregulation of glutaminolysis to generate reducing equivalents for the electron transport chain and amino acids for protein synthesis. Critical enzymes

Noonan syndrome (NS) is an autosomal dominant disorder, and a main feature is congenital heart malformation. About 50% of cases are caused by gain-of-function mutations in the tyrosine phosphatase SHP2/PTPN11, a downstream regulator of ERK/MAPK. Recently it was reported that
