RegulonDB RegulonDB 10.8: Operon Form
   

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




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


Transcription unit          
Name: hcaR
Gene(s): hcaR   Genome Browser M3D Gene expression COLOMBOS
Note(s): The hcaR gene appears to be negatively regulated by ArcA in an indirect way. The regulatory region of the hcaR gene has a putative ArcA-binding site, but when it is partially deleted, the effect of ArcA on the gene is not lost Turlin E,2005.
Promoter
Name: hcaRp
+1: 2668964
