CC   -!- FUNCTION: Regulates transcriptional attenuation of the pyrimidine
CC       nucleotide (pyr) operon by binding in a uridine-dependent manner to
CC       specific sites on pyr mRNA. This disrupts an antiterminator hairpin in
CC       the RNA and favors formation of a downstream transcription terminator,
CC       leading to a reduced expression of downstream genes.
CC       {ECO:0000255|HAMAP-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   -!- SUBUNIT: Homodimer and homohexamer; in equilibrium. {ECO:0000255|HAMAP-
CC       Rule:MF_01219}.
CC   -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC       family. PyrR subfamily. {ECO:0000255|HAMAP-Rule:MF_01219}.
