Pqitp

Promoter activated by VqmAphage in concert with dimethylpyrazin-2-ol (DPO).
Pqtip contains RBS.

Usage and Biology

We assembled Pqtip with BBa_K4645004then transfected into E. coli to sensing the density of bacteria and regulate the circuit.

Characterization

We inserted ECFP reporter (BBa_E0020) behind qitp promoter to verify whether qtip promoter could work as expected in E. coli BL21(DE3). However, bacteria that have transformed this plasmid never shown any fluoresce, even though the sequence didn’t mutate. Later, we found that the sequence of qtip promoter contains more than one initiation codon. This may lead to the losing of efficiency of ECFP. So, we tried to delete sequence between eCFP and the last initiation codon and between eCFP and the penult one. Sad to say, we were not able to make this part work finally.
