RegulonDB RegulonDB 10.10: Operon Form
   

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




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


Transcription unit          
Name: mntH
Gene(s): mntH   Genome Browser M3D Gene expression COLOMBOS
Note(s): MntS makes manganese more available in cells, promoting the ability of manganese to repress mntH transcription by altering cellular manganese pools and global availability, which would perturb MntR and/or Fur activity Waters LS,2011
Evidence: [AISGDTU] Automated inference that a single-gene directon is a transcription unit
