that HilD are each capable of independently inducing expression of the hilC genes
We demonstrate that HilD are each capable of inducing expression of hilC .
We wanted to determine if HilD could induce expression of hilC in the absence of the other regulators .
HilD also induced expression of hilC .
HilD induced expression of hilC approximately threeto fourfold .
These data show that HilD are each capable of independently inducing expression of hilC , consistent with our model that HilD constitute a feed forward regulatory loop .
We show that HilD can each independently activate expression of the hilC genes .
HilD are all also capable of activating expression of hilC independent of each other and comprise a complex feed forward regulatory loop .
For this purpose , we analyzed the effect of L-arabinose on the expression of three HilD-activated genes ( hilC , rtsA , and invH ) .
Furthermore , HilD activates transcription of hilC and of hilD itself by direct binding to both promoters .
