== Function == | |||
[https://www.uniprot.org/uniprot/PYRR_BACSU PYRR_BACSU] 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.[HAMAP-Rule:MF_01219] Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant.[HAMAP-Rule:MF_01219] | |||
