COMMENT On or before Sep 27, 2005 this sequence version replaced
gi:11376215, gi:730440.
[FUNCTION] Regulates transcriptional attenuation of the pyrimidine
nucleotide (pyr) operon by binding in a uridine-dependent manner to
specific sites on pyr mRNA. This disrupts an antiterminator hairpin
in the RNA and favors formation of a downstream transcription
terminator, leading to a reduced expression of downstream genes.
[FUNCTION] Also displays a weak uracil phosphoribosyltransferase
activity which is not physiologically significant.
[CATALYTIC ACTIVITY] UMP + diphosphate = uracil +
5-phospho-alpha-D-ribose 1-diphosphate.
[BIOPHYSICOCHEMICAL PROPERTIES] pH dependence: Optimum pH is 8.2
for UPRTase activity.
[SUBUNIT] Homodimer and homohexamer; in equilibrium.
[MASS SPECTROMETRY] Mass=20263; Mass_error=2; Method=Electrospray;
Range=1-181; Source=PubMed:9488732.
[MISCELLANEOUS] Mutagenesis studies identified four amino acid
residues that seem to be involved directly in binding of the
protein to pyr mRNA: Thr-18, His-22, Arg-141 and Arg-146. Arg-27
and Lys-152 were also likely to be involved in RNA-binding, but
mutations may have altered their subunit-subunit interactions.
Arg-19 was implicated in pyr regulation, but a specific role in
RNA-binding could not be demonstrated.
[MISCELLANEOUS] UMP and UTP incresase the affinity of pyrR for RNA.
[SIMILARITY] Belongs to the purine/pyrimidine
phosphoribosyltransferase family. PyrR subfamily.
