pS

The promoter pS is a kind of σ70-dependent constitutive promoter. It has been confirmed that pS could drive gene expression in wide range of host such as Pseudomonas putida and Azotobacter vinelandii.

Usage and Biology

Given the lack of RBS sequence on pAB1 after zymotic digestion, we introduced pS, a universal promoter, into the plasmid. We synthesized it through the method of dimerization of positive and negative primers, and linked it to the plasmid backbone pAB1.

Then we cut off the GFP gene on pAB1-pS by restriction endonuclease, gaining the usable backbone for reserved.

By these ways, we can link the targeted genes to the vector.

Later, we conducted the effect verification of pS. We put the plates with Pseudomonas aeruginosa under UV and intense fluorescence has been observed, which means that pS is able to come into effect in PAO1.

In conclusion, we successfully constructed the plasmid with the effective promoter.
