dicB-ydfDE-insD-7-intQ operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: dicB-ydfDE-insD-7-intQ
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: dicB-ydfDE-insD-intQ
Gene(s): dicB, ydfD, ydfE, insD-7, intQ   Genome Browser M3D Gene expression COLOMBOS
Note(s): The dicB gene of this operon (dicB-ydfDE-insD-intD) is clearly involved in the replication process |CITS: [3041373][3911021]|, but for the other genes further studies are needed to prove their participation in the same replication process |CITS: [3041373]|. This operon expression is coupled to the replication by the DicA and DicC regulatory effects |CITS: [3911021][6343351]|.

Name: dicBp
+1: 1649597
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 12

Note(s): 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.
