CC -!- FUNCTION: Catalyzes the conversion of uracil and 5-phospho-alpha-D-
CC ribose 1-diphosphate (PRPP) to UMP and diphosphate. {ECO:0000255|HAMAP-
CC Rule:MF_01218}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + UMP = 5-phospho-alpha-D-ribose 1-diphosphate +
CC uracil; Xref=Rhea:RHEA:13017, ChEBI:CHEBI:17568, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:57865, ChEBI:CHEBI:58017; EC=2.4.2.9;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01218};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01218};
CC Note=Binds 1 Mg(2+) ion per subunit. The magnesium is bound as Mg-PRPP.
CC {ECO:0000255|HAMAP-Rule:MF_01218};
CC -!- ACTIVITY REGULATION: Allosterically activated by GTP.
CC {ECO:0000255|HAMAP-Rule:MF_01218}.
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via salvage pathway;
CC UMP from uracil: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01218}.
CC -!- SIMILARITY: Belongs to the UPRTase family. {ECO:0000255|HAMAP-
CC Rule:MF_01218}.
