RegulonDB RegulonDB 10.8: Operon Form
   

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




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


Transcription unit       
Name: potFGHI
Gene(s): potF, potG, potH, potI   Genome Browser M3D Gene expression COLOMBOS
Note(s): There is a putative weak transcriptional termination signal in the potG gene, so synthesis of a part of mRNA may stop at this point.
Evidence: [LTED] Length of transcript experimentally determined
Reference(s): [1] Pistocchi R., et al., 1993
Promoter
Name: potFp2
+1: 893634
Distance from start of the gene: 150
Sequence: atttgttaaataccgttttttaatccgagctatagtctcaaaccctggctaaagttattcTtgcgatgcttttatatagcg

Note(s): We assigned a putative transcription start site to this promoter based on the observation that the majority of the σ54-dependent promoters, whose transcription start sites were determined experimentally, present a distance of 11 nucleotides between the transcription start site and the -12 box Barrios H,1999.
