that a RcsB-RflM protein complex coordinately represses flhDC transcription
a stable RcsB-RflM protein complex is able to efficiently repress flhDC transcription
We next analyzed the mode of action of the RcsB-RflM complex in repression of flhDC gene transcription .
DNA-binding domain of RflM is indispensable to mediate repression of flhDC by the RcsB-RflM complex .
the P1flhDC promoter _ resulting in high affinity binding of a RcsB-RflM heterodimer and repression of flhDC operon transcription
