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:0000250}.
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;
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC       UMP from orotate: step 1/2.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC       family. PyrE subfamily. {ECO:0000305}.
