Protein

Inosine-5'-monophosphate dehydrogenase 2

Gene
impdh2
Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth By similarity.UniRule annotation

Catalytic activityi

Inosine 5'-phosphate + NAD+ + H2O = xanthosine 5'-phosphate + NADH.UniRule annotation

Cofactori

Potassium By similarity.UniRule annotation

Enzyme regulationi

Mycophenolic acid (MPA) is a non-competitive inhibitor that prevents formation of the closed enzyme conformation by binding to the same site as the amobile flap. In contrast, mizoribine monophosphate (MZP) is a competitive inhibitor that induces the closed conformation. MPA is a potent inhibitor of mammalian IMPDHs but a poor inhibitor of the bacterial enzymes. MZP is a more potent inhibitor of bacterial IMPDH By similarity.UniRule annotation
