Isocitrate Dehydrogenase 2 (IDH2) catalyzes the oxidative decarboxylation of isocitrate to alpha-ketoglutarate. There are two subclasses in the IDH family, one of them utilizing NADP+ as the electron acceptor and the other using NAD+. The protein encoded by this gene is the NADP+ dependent isocitrate dehydrogenase found in the mitochondrial. The activity of recombinant human IDH2 was measured by the ability to oxidatively decarboxylate isocitrate to 2-oxoglutarate. The reaction was performed in 25 mM Tris, 0.5 mM MnCl2, 5 mM DTT, pH 7.5
(Assay Buffer), initiated by addition 50 μ L of various concentrations of IDH2 (diluted by Assay Buffer) to 50 µL of substrate mixture consisted of 1 mM NADP+ and 2 mM isocitric acid. The final well serves as a negative control with no IDH2, replaced with 50 μ l assay buffer. Incubated at 25°C for 5min, then read at a wavelength of 340 nm. The specific activity of recombinant human IDH2 is >200 Isocitrate Dehydrogenase 2 (IDH2) catalyzes the oxidative decarboxylation of isocitrate to alpha-ketoglutarate.
