Functioni

This protein is a "fusion" protein encoding four enzymatic activities of the pyrimidine pathway (GATase, CPSase, ATCase and DHOase).1 Publication

Miscellaneous

GATase (glutamine amidotransferase) and CPSase (carbamoyl phosphate synthase) form together the glutamine-dependent CPSase (GD-CPSase) (EC 6.3.5.5).Curated

Catalytic activityi

2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.1 Publication
Carbamoyl phosphate + L-aspartate = phosphate + N-carbamoyl-L-aspartate.1 Publication
(S)-dihydroorotate + H2O = N-carbamoyl-L-aspartate.1 Publication

Cofactori

Protein has several cofactor binding sites:
  • Zn2+2 PublicationsNote: Binds 3 Zn2+ ions per subunit (for dihydroorotase activity).2 Publications
  • Mg2+PROSITE-ProRule annotation, Mn2+PROSITE-ProRule annotationNote: Binds 4 magnesium or manganese ions per subunit.PROSITE-ProRule annotation

Enzyme regulationi

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

    Involvement in diseasei

    Epileptic encephalopathy, early infantile, 50 (EIEE50)2 Publications
    The disease is caused by mutations affecting the gene represented in this entry.
    Disease descriptionA form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE50 is an autosomal recessive, progressive disease with onset in infancy and favorable response to treatment with oral uridine.

    Post-translational modificationi

    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.3 Publications
