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




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


Transcription unit          
Name: rob
Gene(s): rob   Genome Browser M3D Gene expression COLOMBOS
Note(s): RpoS is involved in the transcription of the rob gene, but it appears that another σ factor, probably σ70 also regulates rob expression 7476863
The rob gene is expressed predominantly in the stationary phase 7476863 In addition, it was proved in an experiment with increasing concentrations of the tetracycline antibiotic that rob gene expression was induced in low concentrations (1.5 and 4 mg/L) but not in high ones (10 mg/L); this suggests that the product of this gene plays a role under this condition 17426813
Decanoate represses the robp promoter independently of Rob 22753060 Rob does not directly bind salicylate; instead, salicylate may regulate Rob at the transcriptional level 22753060 Salicylate activates the rob promoter independently of the marRAB operon 22753060
