RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit       


Transcription unit       
Name: rfbACX
Gene(s): rfbX, rfbC, rfbA   Genome Browser M3D Gene expression COLOMBOS
Evidence: [PAGTSBP] Products of adjacent genes in the same biological process
Promoter
Name: rfbAp
+1: Unknown
Note(s): Zaslaver et al. demonstrated in 2006, by means of a library of fluorescent transcription fusions, that this promoter can be transcribed in vitro Zaslaver A,2006. Based on this, a putative promoter was suggested, but the +1 site of the transcription initiation has not been determined, although there exists promoter activity.
Evidence: [IEP]
Reference(s): [4] Zaslaver A., et al., 2006


RNA cis-regulatory element    
Regulation, transcriptional elongation  
Attenuator type: Translational
Strand: reverse
Evidence: [ICA] Inferred by computational analysis
Reference(s): [5] Merino E, et al., 2005
  Structure type Energy LeftPos RightPos Sequence (RNA-strand)
  terminator -8.8 2111040 2111066 tagtttttgcATCTTGTTCGTGATGGTGGAGCAAGAtgaattaaaa
Notes: "The provided "Sequence" is that of the RNA strand, i.e. U's are shown instead of T's and regulators on the reverse strand will appear as the reverse complement of the sequence delimited by LeftPos-RigtPos"
REGULATION, RNA cis-regulatory element:  
Rfam type: Cis-reg
Strand: reverse
Evidence: [ICA] Inferred by computational analysis
Reference(s): [6] null null
  Description Rfam score Left Pos Right Pos Sequence (RNA-strand)
