RegulonDB RegulonDB 11.0: Operon Form
   

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




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


Transcription unit          
Name: cspD
Gene(s): cspD   Genome Browser M3D Gene expression COLOMBOS
Note(s): cspD expression is induced during stationary phase and it is independent of σS Uppal S,2014 In addition, cspD is associated with biofilms and persister cell formation Uppal S,2014
CRP is activated via a class I-type mechanism that involves cspD expression Uppal S,2014 Based on mutant alleles, it was determined that the AR1 domain in CRP is critical for cspD activation, whereas the AR2 domain of CRP is not necessary Uppal S,2014
The mRNA produced by the cspD gene has been observed mainly in the poles of the cell Kannaiah S, Livny J, Amster-Choder O,2019.

Promoter
Name: cspDp
+1: 922676
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 86
Sequence: tgccccttgtcccctgtcaaatgcttgacggctcgccctaattctctaaattgtatttctAgagttggcgaggttttgaac
                         -35                   -10          +1                   
Note(s): The activity of this promoter appears to be decreased in the presence of σE. It is repressed during the first 5 minutes following σE induction and decreased from 5 to 10 minutes and from 10 to 20 minutes after induction of the σ factor Lacoux C,2020.
