RegulonDB RegulonDB 10.8: Operon Form
   

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




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


Transcription unit       
Name: proS
Gene(s): proS   Genome Browser M3D Gene expression COLOMBOS
Note(s): The proS (drpA) gene codes for the prolyl-tRNA synthetase required for RNA synthesis in the cell Zhou Z,1990 The proS gene has a simple DNA structure, with a single transcription start site, a σ70 promoter and one Rho-independent terminator. It has been reported that the proS gene is a target of DnaA regulation during DNA replication, based on sequence similarity Zhou Z,1990
