Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 1.6Å Ligands: SM, SO4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT 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] Evolutionary Conservation Check, as determined by ConSurfDB.
