RegulonDB RegulonDB 11.1: Operon Form

nsrR-rnr-rlmB-yjfIJ operon and associated TUs in Escherichia coli K-12 genome

Name: nsrR-rnr-rlmB-yjfIJ
This page displays every known transcription unit of this operon and their known regulation.

Transcription unit       
Name: nsrR-rnr-rlmB-yjfI
Gene(s): nsrR, rnr, rlmB, yjfI   Genome Browser M3D Gene expression COLOMBOS
Note(s): The nsrRp promoter is strong, and its nsrR mRNA is translated inefficiently. Translation of nsrR initiates with a GUG start codon, which is 2- to 3-fold less efficient in translation initiation than the more commonly used AUG. Conversion of this start codon from the wild-type GUG to AUG increased the efficiency of translation of nsrR mRNA and the abundance of NsrR Chhabra S,2015
