General annotation (Comments)
| Function | This protein is a "fusion" protein encoding four enzymatic activities of the pyrimidine pathway (GATase, CPSase, ATCase and DHOase). |
| Catalytic activity | 2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate. Carbamoyl phosphate + L-aspartate = phosphate + N-carbamoyl-L-aspartate. (S)-dihydroorotate + H2O = N-carbamoyl-L-aspartate. |
| Cofactor | Binds 1 zinc ion per subunit (for dihydroorotase activity) Potential. |
| Enzyme regulation | Allosterically regulated and controlled by phosphorylation. 5-phosphoribose 1-diphosphate is an activator while UMP is an inhibitor of the CPSase reaction. |
| Pathway | |
| Subunit structure | Homohexamer. |
| Subcellular location | |
| Miscellaneous | GATase (glutamine amidotransferase) and CPSase (carbamoyl phosphate synthase) form together the glutamine-dependent CPSase (GD-CPSase) (EC 6.3.5.5). |
| Sequence similarities | In the central section; belongs to the DHOase family. Contains 2 ATP-grasp domains. Contains 1 glutamine amidotransferase type-1 domain. |
