dsrA+lacI+PlacI+hns+ProU+GFP

In our project, we combined temperature promoter dsrA and salt-concentration promoter proU as a logical gate controlled by salt-concentration and temperature to realize the aim of producing antibacterial, PLA. dsrA is a temperature control promoter. The temperature range of dsrA is from 25 degree to 42 degree. With temperature increase, the promote efficiency is getting higher. [1]The salt-concentration promoter proU provides sensitivity to the salt concentration to human skin. proU is a promoter existed in E.coli, induced by low salt concentration. And the H-NS is a global-regulated protein which could bind to genome and specifically inhibit proU.[2]

In our design, our engineering bacteria usually put in a lotion container and store at room temperature. When temperature stays below 37 degree, the temperature promoter will not work.

Fig.1 our circuits in room temperature.


The function of PlacI has became a constitutive promoter. The global regulate protein H-NS will be express to inhibit proU. Then the logical gate will be “off” state.

On the other hand, when we use the lotion on the skin, temperature reached 37 degree, the repressor protein LacI will be expressed to inhibit PlacI, the H-NS won’t be revealed. Then, once people sweat, the Na+ and Cl- will induce proU, the logical gate became “on” state.
