RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit          
Name: fadH
Gene(s): fadH   Genome Browser M3D Gene expression COLOMBOS
Note(s): Repression of fadH transcription by the ArcAB system is additive to FadR repression under anaerobic conditions Feng Y,2010
Evidence: [ICWHO] Inferred computationally without human oversight
Promoter
Name: fadHp
+1: 3231624
Distance from start of the gene: 41
Sequence: ccatcacaaaccccgcactccccttttcccttttctccggcgacggctaaattagaactcAtccgaccacataacaattat
Note(s): The CRP-cAMP complex activates the fadH promoter; however, the absence of CRP-cAMP reduces the repression of fadH expression by FadR and ArcA-ArcB. This suggests that HipB may regulate fadH expression in cooperation with other DNA-binding proteins Lin CY,2013
