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




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


Transcription unit          
Name: fliLMNOPQR
Gene(s): fliL, fliM, fliN, fliO, fliP, fliQ, fliR   Genome Browser M3D Gene expression COLOMBOS
Note(s): In a study where it was shown that the L-tryptophan eradicated persister cells, it was observed that the exogenous amino acid downregulated the expression of fliLMOPQR as well as other flagellar genes 31271063.
