RegulonDB RegulonDB 10.10: Operon Form
   

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




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


Transcription unit       
Name: sibA
Gene(s): sibA   Genome Browser M3D Gene expression COLOMBOS
Note(s): Based on Northern and 5'-3' RACE analysis, the sibA gene produces two distinct transcripts. The 3' end shorter transcript could be a result of processing Fozo EM,2008
Evidence: [BTEI] Boundaries of transcription experimentally identified
[ICWHO] Inferred computationally without human oversight
