Cofactor	Magnesium By similarity. HAMAP MF_01208
Enzyme regulation	Inhibited by sulfate and phosphate ions. Ref.6
Pathway	Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2. HAMAP MF_01208
Subunit structure	Homodimer. Ref.1 Ref.6
Sequence similarities	Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrE subfamily.
