Function
function
Catalyzes the conversion of uracil and 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) to UMP and diphosphate.
Catalytic activity
- diphosphate + UMP = 5-phospho-alpha-D-ribose 1-diphosphate + uracil
Cofactor
Note: Binds 1 Mg2+ 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.
