Flagellar transcriptional regulator FlhC

Gene

flhC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Functions in complex with FlhD as a master transcriptional regulator that regulates transcription of several flagellar and non-flagellar operons by binding to their promoter region. Activates expression of class 2 flagellar genes, including fliA, which is a flagellum-specific sigma factor that turns on the class 3 genes. Also regulates genes whose products function in a variety of physiological pathways.3 Publications

Expressioni

Inductioni

Expression is regulated by a large number of systems, including induction by quorum sensing via the two-component regulatory system QseB/QseC, induction by cAMP-CRP, repression by high osmolarity via OmpR and repression by H-NS.3 Publications

Interactioni

Subunit structurei

Heterohexamer composed of two FlhC and four FlhD subunits. Each FlhC binds a FlhD dimer, forming a heterotrimer, and a hexamer assembles by dimerization of two heterotrimers.1 Publication
