AhpCpD1

AhpCpD1
We improve the function of a BioBrick Part: ahpC promoter(K362001)designed by [http://2010.igem.org/Team:KIT-Kyoto/Parts 2010 KIT-Tokyo team] into four versions.On PartRegistry, the complex part(according to [http://ecocyc.org/ECOLI/new-image?object=EG11384 Ecocyc]) composition contains hybrid promoters, shared TFBS (Transcription Factor Binding Site), and reverse promoter DsbG.
Improvement of ahpC promoter(Part:K362001)
OxyR binding to the ahpC-proximal site leads to the induction of both dsbG and ahpC transcripts, while OxyR binding to the dsbG-proximal site leads to the induction of a second ahpC transcript. This transcript of ahpC and the transcript of dsbG overlap by over 100 nucleotides.
The intergenic region between dsbG and ahpC carries two binding sites for OxyR, a dsbG-proximal site, located 54 bp upstream of the dsbG start codon; an ahpC-proximal site, located 290 bp upstream of the dsbG start codon.

Usage and Biology

There are two TFBSs between AhpCp1 and reverse DsbGp. OxyR binding to the ahpC-proximal site leads to the induction of both dsbG and ahpC transcripts.

Once ROS(Reactive Oxygen Species) oxidizes OxyR, making OxyR interact with the TFBS between AhpCp1 and DsbGp, dual-directional transcription will occur. It can be take advantages of by certain special circuit design.
