RegulonDB RegulonDB 11.0: Operon Form

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

This page displays every known transcription unit of this operon and their known regulation.

Transcription unit          
Gene(s): flgB, flgC, flgD, flgE, flgF, flgG, flgH, flgI, flgJ   Genome Browser M3D Gene expression COLOMBOS
Note(s): flgBCDEFGHIJ expression is enhanced by AtoSC in the presence of acetoacetate Theodorou MC, Theodorou EC, Kyriakidis DA,2012.
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 flgBCDEFGHIJ as well as other flagellar genes Li Y, Liu B, Guo J, Cong H, He S, Zhou H, Zhu F, Wang Q, Zhang L,2019.
