PYRR, THE BACILLUS SUBTILIS PYRIMIDINE BIOSYNTHETIC OPERON REPRESSOR, DIMERIC FORM
Template:ABSTRACT PUBMED 9551555
Function
[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]
