Comments [?]

Function Catalyzes the conversion of uracil and 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) to UMP and diphosphate.
Catalytic activity RHEA:13017: diphosphate + UMP = 5-phospho-alpha-D-ribose 1-diphosphate + uracil
EC 2.4.2.9
Cofactor Mg(2+)
Note: Binds 1 Mg(2+) ion per subunit. The magnesium is bound as Mg-PRPP.
Activity regulation Allosterically activated by GTP.
Pathway Pyrimidine metabolism; UMP biosynthesis via salvage pathway; UMP from uracil: step 1/1.
Similarity Belongs to the UPRTase family.
