>TIGR01302 IMP_dehydrog inosine-5'-monophosphate dehydrogenase; InterPro: IPR005990 Synonyms: Inosine-5'-monophosphate dehydrogenase, Inosinic acid dehydrogenase IMP dehydrogenase (1.1.1.205 from EC,IMPDH) catalyzes the rate-limiting reaction of de novo GTP biosynthesis, the NAD-dependent reduction of IMP into XMP . Inosine 5-phosphate + NAD+ + H2O = xanthosine 5-phosphate + NADH IMP dehydrogenase is associated with cell proliferation and is a possible target for cancer chemotherapy. Mammalian and bacterial IMPDHs are tetramers of identical chains. There are two IMP dehydrogenase isozymes in humans . IMP dehydrogenase nearly always contains a long insertion that has two CBS domains within it and adopts a TIM barrel structure.; GO: 0003938 IMP dehydrogenase activity, 0006177 GMP biosynthetic process.
