Investigating the Pyrr-Pyr mRNA Interaction Through Site-Directed Mutagenesis of the PyrR Protein
… the product of the first gene of the operon, PyrR, and the downstream products of the pathway, uridine nucleotides. Regulation occurs through a transcriptional attenuation mechanism in which PyrR binds in the presence of UMP or UTP to an anti anti-terminator RNA stem-loop and promote early …

The regulatory roles of PyrR and Crc in pyrimidine metabolism in Pseudomonas aeruginosa
… biosynthesis has been identified and designated pyrR. The pyrR gene product was purified to homogeneity and found to have a monomeric molecular mass of 19 kDa. The pyrR gene is located directly upstream of the pyrBC' genes in the pyrRBC' operon. Insertional mutagenesis of pyrR led to a 50- 70% …
