General annotation (Comments)

Function

This protein is a "fusion" protein encoding four enzymatic activities of the pyrimidine pathway (GATase, CPSase, ATCase and DHOase) By similarity. HAMAP-Rule MF_00001

Catalytic activity

2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate. HAMAP-Rule MF_00001

Carbamoyl phosphate + L-aspartate = phosphate + N-carbamoyl-L-aspartate. HAMAP-Rule MF_00001

(S)-dihydroorotate + H2O = N-carbamoyl-L-aspartate. HAMAP-Rule MF_00001

Cofactor

Binds 3 zinc ions per subunit (for dihydroorotase activity) By similarity.

Enzyme regulation

Allosterically regulated and controlled by phosphorylation. 5-phosphoribose 1-diphosphate (PRPP) is an activator while UMP and UTP are inhibitors of the CPSase reaction By similarity. HAMAP-Rule MF_00001

Pathway

Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 1/3. HAMAP-Rule MF_00001

Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 2/3.

Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 3/3.

Subunit structure

Homohexamer By similarity. HAMAP-Rule MF_00001

Subcellular location

Cytoplasm By similarity. Nucleus By similarity. Note: Cytosolic and unphosphorylated in resting cells, translocates to the nucleus in response to EGF stimulation, nuclear import promotes optimal cell growth By similarity. HAMAP-Rule MF_00001

Post-translational modification

Activated by MAP kinase (Erk1/2) phosphorylation just prior to the S phase of the cell cycle, when the demand for pyrimidine nucleotides is greatest, and down-regulated as the cells emerge from S phase by protein kinase A (PKA) phosphorylation. Phosphorylation at Ser-1859 by RPS6KB1 downstream of MTOR promotes oligomerization and stimulates dihydroorotase activity. Phosphorylation at Ser-1406 reduces sensitivy to feedback inhibition by UTP By similarity. HAMAP-Rule MF_00001

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.
