UniProtKB - Q04K45 (PYRR_STRP2)
Protein
Bifunctional protein PyrR
Gene
pyrR
Organism
Streptococcus pneumoniae serotype 2 (strain D39 / NCTC 7466)
Status
Functioni
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.UniRule annotation
Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant.UniRule annotation
