Design Notes
One of our team's goal is to design a fatty-acid-detecting system, using the natural fatty-acid sensing genes, including fatty acid sensing promotor, pfadBA and the natural repressor, FadR.
At first, from the papers we reviewed, we assumed that FadR gene within the Escherichia coli(E. coli) bacteria will be normally expressed to a certain content that pfad promotor will be repressed. The first experiment we conducted showed that the real situation might not be what we expected, so we decided to clone out the FadR gene and construct it into our circuit. We prepared our FadR gene by doing the PCR of the genomic DNA of E. coli. K-12 DH5α strain. Later, we incorporated the FadR gene we cloned into BBa_J04500, with plac(R0010) and RBS(B0034) to test the function, forming BBa_K817007 part. We transformed both our pfad-mRFP part(BBa_K817033) and BBa_K817007 part into E. coli. K-12 DH5α to do the test. Functional results can be found in the result website of 2012 iGEM_Taida(http://2012.igem.org/Team:NTU-Taida/Result)
The FadR gene had already been sequenced and compared. The result shows 100%-fit with the sequence in the NCBI FadR gene sequence database of E. coli. K-12 genome.
