NADP-dependent isocitrate dehydrogenase (EC 1.1.1.42) was purified to electrophoretic homogeneity from an extremely thermophilic bacterium, Thermus thermophilus HB8, and shown to be a dimeric protein of molecular weight 115,000, with a pI of 5.5. The amino acid composition of the

The enzyme isocitrate dehydrogenase 1 (IDH1) catalyzes the conversion of isocitrate to alpha-ketoglutarate (αKG) and has emerged as an important therapeutic target for glioblastoma multiforme (GBM). Current methods for assaying IDH1 remain poorly suited for high-throughput screening of IDH1 antagonists.
