Native pFadD promoter regulating downstream RFP
pFadD promoter is one of the regulator in the enzymes of fatty acid biosynthesis in E. coli. It is composed of two fadR recognition sites, and one CRP binding site. The fatty acid metabolism system of E. coli is consist of many parts, fadD, fadL, fadR, fadA, etc. Interestingly, each enzyme in this family has its own different sequence of fadR recognition site in its promoter, which makes these promoter having different strength, yet can still be interchangeable for us to apply in our system. Based on this fact, we tried pFadD promoter to take place of the weak pFadBA promoter. With two fadR recognition sites native in pFadD, we assume a better result in the sensitivity and a lower leakage in our pFadD promoter.
