Purification of IMP dehydrogenase from rat hepatoma 3924A. 1987

T Ikegami, and Y Natsumeda, and G Weber

IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of de novo GTP biosynthesis and a promising target for cancer chemotherapy, was purified 4860-fold to homogeneity from rat hepatoma 3924A by a method including affinity chromatography in which IMP is bound to epoxy-activated Sepharose 6B. This affinity gel provided a specific elution of the enzyme with 0.5 mM IMP. The final enzyme preparation gave a single band with a molecular weight of 60,000 +/- 1000 on sodium dodecyl sulfate polyacrylamide gel electrophoresis.
