123 COMMENT On or before Sep 27, 2005 this sequence version replaced
124 gi:11376215, gi:730440.
125 [FUNCTION] Regulates transcriptional attenuation of the pyrimidine
126 nucleotide (pyr) operon by binding in a uridine-dependent manner to
127 specific sites on pyr mRNA. This disrupts an antiterminator hairpin
128 in the RNA and favors formation of a downstream transcription
129 terminator, leading to a reduced expression of downstream genes.
130 [FUNCTION] Also displays a weak uracil phosphoribosyltransferase
131 activity which is not physiologically significant.
132 [CATALYTIC ACTIVITY] UMP + diphosphate = uracil +
133 5-phospho-alpha-D-ribose 1-diphosphate.
134 [BIOPHYSICOCHEMICAL PROPERTIES] pH dependence: Optimum pH is 8.2
135 for UPRTase activity.
136 [SUBUNIT] Homodimer and homohexamer; in equilibrium.
137 [MASS SPECTROMETRY] Mass=20263; Mass_error=2; Method=Electrospray;
138 Range=1-181; Source=PubMed:9488732.
139 [MISCELLANEOUS] Mutagenesis studies identified four amino acid
140 residues that seem to be involved directly in binding of the
141 protein to pyr mRNA: Thr-18, His-22, Arg-141 and Arg-146. Arg-27
142 and Lys-152 were also likely to be involved in RNA-binding, but
143 mutations may have altered their subunit-subunit interactions.
144 Arg-19 was implicated in pyr regulation, but a specific role in
145 RNA-binding could not be demonstrated.
146 [MISCELLANEOUS] UMP and UTP incresase the affinity of pyrR for RNA.
147 [SIMILARITY] Belongs to the purine/pyrimidine
148 phosphoribosyltransferase family. PyrR subfamily.
