RegulonDB RegulonDB 11.0: Operon Form

cnoX operon and associated TUs in Escherichia coli K-12 genome

Name: cnoX
This page displays every known transcription unit of this operon and their known regulation.

Transcription unit       
Name: ybbN
Gene(s): cnoX   Genome Browser M3D Gene expression COLOMBOS
Name: ybbNp1
+1: 518490
Sigma Factor: Sigma32 Sigmulon
Distance from start of the gene: 211
Sequence: caaccagacgcaaagtgataaaccagtcgaaaatcccggcatcgccgcccgctttacgttGggaccggaagcggtggtgga
                           -35                -10           +1                   
Note(s): The sigma factor was determined by transcription profiling experiments and a bioinformatics approach Zhao K,2005 We assigned a putative transcriptional start site to this promoter based on the observation that the majority of the promoters, whose transcriptional start sites were determined experimentally, present a distance of 6 nucleotides between the transcriptional start site and the -10 box.
