pyrB | Aspartate carbamoyltransferase; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family. (311 aa) | ||||
pyrR1 | Pyrimidine operon regulator; 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). Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily. (180 aa) | ||||
pyrAA | Carbamoyl-phosphate synthase,pyrimidine-specific, small chain; Belongs to the CarA family. (364 aa) |
