RegulonDB RegulonDB 10.8: Operon Form
   

murQP-yfeW operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: murQP-yfeW
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: murQP
Gene(s): murQ, murP   Genome Browser M3D Gene expression COLOMBOS
Note(s): murR and murQ are divergently orientated and expressed from nonoverlapping face-to-face (convergent) promoters, and their transcripts are complementary at the 5' end. CRP controls positively murQP expression and it also may affect murR transcription as a consequence of this unusual promoter arrangement (face-to-face) Jaeger T,2008
Evidence: [PAGTSBP] Products of adjacent genes in the same biological process
Reference(s): [1] Jaeger T., et al., 2008
Promoter
Name: murQp1
+1: 2545733
Sigma Factor: Sigma70, Sigma38
Distance from start of the gene: 40
