RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit       
Name: sibB
Gene(s): sibB   Genome Browser M3D Gene expression COLOMBOS
Note(s): Based on Northern and 5'-3' RACE analysis, the sibB 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
