RegulonDB RegulonDB 10.8: Operon Form
   

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




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


Transcription unit       
Gene(s): sfmH, sfmF   Genome Browser M3D Gene expression COLOMBOS
Note(s): Although a putative σ54-binding site was identified upstream of the sfmF gene and the gene expression was affected in microarray experiments in a mutant
σ54 strain and a σ54-overexpressing strain, ChIP assays demonstrated that σ54 does not bind upstream of sfmF Zhao K,2010 Therefore, we did not assign a σ54 promoter to this gene.
Evidence: [ICWHO] Inferred computationally without human oversight
