rfaD-waaFCL operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit       
Name: rfaDFCL
Gene(s): rfaD, waaF, waaC, waaL   Genome Browser M3D Gene expression COLOMBOS
Note(s): It was experimentally demonstrated that the Rho protein negatively regulates expression of the genes waaF and waaL Hafeezunnisa M, Sen R,2020. Rho loading sites (rut sites) were identified upstream of these two genes Hafeezunnisa M, Sen R,2020.
Evidence: [BTEI] Boundaries of transcription experimentally identified
Reference(s): [1] Klena JD., et al., 1992
Promoter
Name: rfaDp3
+1: 3793865
Sigma Factor: Sigma32 Sigmulon
Distance from start of the gene: 122
Sequence: gcactattcacatgcaaaaccaacatccgccatgaaggactagctaaaacccaaactagtTtgttgcaattagcatccttg
