RegulonDB RegulonDB 10.9: Operon Form

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

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

Transcription unit       
Name: arnBCADTEF
Gene(s): arnB, arnC, arnA, arnD, arnT, arnE, arnF   Genome Browser M3D Gene expression COLOMBOS
Note(s): arnBCAD transcript levels are increased under growth conditions with low Mg2+ concentrations 25605366.
arnA gene expression is downregulated upon L-valine addition (isoleucine starvation) in the cellular growth medium 32211022; this effect was observed during the first 5 minutes of the amino acid addition, but then arnA expression returned to steady-state levels 32211022.
Evidence: [ICWHO] Inferred computationally without human oversight
