Protein: Multifunctional protein pyr-1 [Includes: Glutamine-dependent carbamoyl-phosphate synthase (EC 6.3.5.5); Glutamine amidotransferase (GATase) (GLNase) (EC 3.5.1.2); Ammonium-dependent carbamoyl phosphate synthase (CPS) (CPSase) (EC 6.3.4.16); Aspartate carbamoyltransferase (EC 2.1.3.2); Dihydroorotase (EC 3.5.2.3)] (Q18990)
Organism: Caenorhabditis elegans
Function: This protein is a 'fusion' protein encoding four enzymatic activities of the pyrimidine pathway (GATase, CPSase, ATCase and DHOase) (By similarity). Involved in the elongation of the pharyngeal isthmus during development, probably by providing precursors of UDP-sugars required for heparan sulfate proteoglycan biosynthesis. Regulates the organization of the actin and intermediate filaments cytoskeleton in the pharyngeal muscles.
Interaction partners:
- Dihydroorotate dehydrogenase
- glutamate synthase
- Amidophosphoribosyltransferase
- Probable Golgi transport protein 1
- Dihydropyrimidine dehydrogenase [NADP
- Adenylosuccinate synthetase
- Cytochrome-b5 reductase
- Uridine 5'-monophosphate synthase
- Trifunctional purine biosynthetic protein adenosine-3
- Dihydropyrimidinase 1
