CC -!- FUNCTION: Catalyzes the transfer of a ribosyl phosphate group from 5-
CC phosphoribose 1-diphosphate to orotate, leading to the formation of
CC orotidine monophosphate (OMP). {ECO:0000256|HAMAP-Rule:MF_01208}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + orotidine 5'-phosphate = 5-phospho-alpha-D-
CC ribose 1-diphosphate + orotate; Xref=Rhea:RHEA:10380,
CC ChEBI:CHEBI:30839, ChEBI:CHEBI:33019, ChEBI:CHEBI:57538,
CC ChEBI:CHEBI:58017; EC=2.4.2.10; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01208};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01208};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC UMP from orotate: step 1/2. {ECO:0000256|ARBA:ARBA00004889,
CC ECO:0000256|HAMAP-Rule:MF_01208}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01208}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. PyrE subfamily. {ECO:0000256|HAMAP-Rule:MF_01208}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01208}.
