In our project, we combined temperature promoter dsrABBa_K2570015 and salt-concentration promoter proUBBa_K2467001 as a logical gate controlled by salt-concentration and temperature to realize the aim of producing antibacterial, PLA. dsrABBa_K2570015 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 proUBBa_K2467001 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-NSBBa_K2570016 is a global-regulated protein which could bind to genome and specifically inhibit proU.[2]
This year the iGEM Edinburgh_OG team improved the BBa_K191006 part to fulfil the gold medal criteria.A core principle of the Biobrick foundation is to bring standardisation in a field that is constantly changing and evolving. Standardising biological parts and their assembly allows for projects to focus less on assembly of genetic constructs and more on design and testing.
