Disease relevance of fliA

  • One involved the arabinose-induced expression of plasmid-encoded sigma(28)(Ct) in a strain of Escherichia coli defective in the sigma(28) structural gene, fliA [1].
 

High impact information on fliA

  • QseBC activates transcription of flhDC, which is the master regulator for the flagella and motility genes and, in the absence of flhD, QseBC failed to activate the transcription of fliA [2].
 

Anatomical context of fliA

  • The presence of flagella was also found to be important as qseB and fliA mutants (which lack flagella) had less biofilm than the isogenic paralyzed motA strain (threefold less thickness and 15-fold less surface coverage) [3].
