RegulonDB RegulonDB 10.7: Operon Form
   

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




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


Transcription unit          
Name: pgaABCD
Gene(s): pgaD, pgaC, pgaB, pgaA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The pgABCD operon was inferred based on the facts that its genes are adjacent, encoded in the same direction, and their products are all involved in biofilm formation |CITS:[15090514]|.
H-NS represses pgaA transcription, although it is unknown if the effect is direct or indirect |CITS:[28470798]|.
