Crystal Structure of PyrR, The Regulator Of The Pyrimidine Biosynthetic Operon In Bacillus caldolyticus, UMP-bound form
| ||||||||||||
Structural highlights
FunctionPYRR_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. Evolutionary Conservation![]() Check, as determined by ConSurfDB.
