In vivo analyses indicate that LeuO activates hilE transcription .
We also observed that a hilE null mutation increased the HilD levels in the absence of LeuO , in the occurrence of autogenous activation of hilD transcription .
We also observed that a hilE null mutation increased the HilD levels in the absence of LeuO , in the inhibition of HilD activity by HilE .
We also observed that a hilE null mutation increased the HilD levels in the absence of LeuO , in accordance with two well known facts .
that LeuO may activate hilE expression
that LeuO may activate hilE expression
To test whether LeuO is an activator of a hilE : : lacZ translational fusion was constructed on the Salmonella chromosome .
To test whether LeuO is an activator of hilE expression : : lacZ translational fusion was constructed on the Salmonella chromosome .
that LeuO might activate hilE transcription
LeuO activates transcription of hilE
that the transcriptional regulator LeuO directly activates transcription of hilE
The LysR-type regulator LeuO has been shown to activate hilE transcription to repress HilD activity .
the major one involves the induction of hilE transcription by LeuO
