RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit       
Name: rpiA
Gene(s): rpiA   Genome Browser M3D Gene expression COLOMBOS
Note(s): A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for rpiA. This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
