Usage and Biology

This part consists of the ArsR repressor binding site and the ArsR gene encoding the arsR repressor protein, together with its ribosome binding site. Addition of any other genes to the 3' end of this part will result in their expression being dependent on the presence of sodium arsenate or sodium arsenite. Arsenite or arsenite anion binds to the repressor protein ArsR, resulting in inability to repress the promoter.

Results

We used this part to build a new arsenic induction loop through it. Therefore, we first added 10μl ddH2O to the corresponding hole, and then took PCR was performed at 1 μl, and the corresponding DNA fragment was obtained.

Then we performed PCR on the promoter fragment and ArsR fragment in this fragment, and the results are as follows.
