RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit          
Name: metF
Synonym(s): OP00308
Gene(s): metF   Genome Browser M3D Gene expression COLOMBOS
Note(s): The regulatory effect of MetJ on the promoter metFp is as yet not known. However, we assigned a negative effect to this regulatory interaction based on two facts: the protein's binding site is very close to the promoter, and MetJ is known to act, so far without exceptions, as a negative regulator.
