These observations support the model that Lrp acts as a conjugation activator by promoting traJ transcription , whereas Dam methylation acts as a conjugation repressor by activating FinP RNA synthesis .
This result suggested that Lrp activates the transcription of traJ .
The concomitant observation that the tra operon remains repressed in TraJ-background is also relevant , as it suggests that Lrp activates the tra operon indirectly by enhancing traJ transcription .
