Protein attributes
| Sequence length | 488 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | 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. HAMAP-Rule MF_01964 |
| Catalytic activity | Inosine 5'-phosphate + NAD+ + H2O = xanthosine 5'-phosphate + NADH. HAMAP-Rule MF_01964 |
| Cofactor | Potassium By similarity. |
| Enzyme regulation | 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. HAMAP-Rule MF_01964 |
| Pathway | Purine metabolism; XMP biosynthesis via de novo pathway; XMP from IMP: step 1/1. HAMAP-Rule MF_01964 |
| Subunit structure | Homotetramer By similarity. |
| Sequence similarities | Belongs to the IMPDH/GMPR family. Contains 2 CBS domains. |
