CC   -!- FUNCTION: Regulates the transcription of the pyrimidine nucleotide
CC       (pyr) operon in response to exogenous pyrimidines. {ECO:0000255|HAMAP-
CC       Rule:MF_01219}.
CC   -!- FUNCTION: Also displays a weak uracil phosphoribosyltransferase
CC       activity which is not physiologically significant. {ECO:0000255|HAMAP-
CC       Rule:MF_01219}.
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_01219};
CC   -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC       family. PyrR subfamily. {ECO:0000255|HAMAP-Rule:MF_01219}.
