RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit          
Name: flgBCDEFGHIJ
Gene(s): flgB, flgC, flgD, flgE, flgF, flgG, flgH, flgI, flgJ   Genome Browser M3D Gene expression COLOMBOS
Note(s): flgBCDEFGHIJ expression is enhanced by AtoSC in the presence of acetoacetate 22083893.
In a study where it was shown that the L-tryptophan eradicated persister cells, it was observed that the exogenous amino acid downregulated the expression of flgBCDEFGHIJ as well as other flagellar genes 31271063.

Promoter
Name: flgBp
+1: 1130993
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 25
Sequence: gacccattttgcgtttattccgccgataacgcgcgcgtaaaggcatttaagctgatggcaGaattttgatacctgcggagg
                          -35                   -10         +1                   
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.
