| - | [[ | + | [[https://www.uniprot.org/uniprot/PYRR_BACCL PYRR_BACCL]] 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 (Probable). Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. |
