RegulonDB RegulonDB 11.0: Operon Form
   

ptrA-recBD operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: ptrA
Gene(s): ptrA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The transcript of ptrA is increased after σE induction, as observed in high-throughput analysis of gene expression Lacoux C,2020.
Reference(s): [1] Claverie-Martin F., et al., 1987
Promoter
Name: ptrAp
+1: 2959011
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 127
Sequence: aatcagtcatgagtgctgtataaaaattgcgcaatctatccgcttactttatgatgcgcaCcagtcacggactgatggtta
                           -35                    -10       +1                   
Note(s): A potential σ54 or putative nitrogen-regulated (CTGGCAGATGATTTGCG) promoter is located downstream from the -35 and -10 regions of ptrAp Claverie-Martin F,1987. However, whether this promoter is functional in vivo has not been determined Claverie-Martin F,1987.
