RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit          
Name: cusCFBA
Synonym(s): ylcBCD-ybdE
Gene(s): cusC, cusF, cusB, cusA   Genome Browser M3D Gene expression COLOMBOS
Note(s): cusCFBA expression is induced under Zn excess in a CusR-dependent way Xu Z,2019.
This transcription unit may even include the pheP gene that is downstream of the cusA gene.
cusB expression is increased at least 5-fold by indole Hirakawa H,2005.
The mRNA that contains the cusA gene has been observed mainly in the cellular membrane 31540875.
