PBAD/araC_rbs_fimE(wild-type)
The fim switch is inverted by FimE.The FimE protein inverts the fim switch predominantly in [ON] state to [OFF] state.
In order to assay the function of our FimE, we added a GFP coding sequence on the downstream of the fim switch(wild-type).The fim switch[default ON](wild-type)_gfp (BBa_K1632007) emitts fluorescence when expressed, while the fim switch[default OFF](wild-type)_gfp(BBa_K1632008) does not emit florescence when expressed. We also added PBAD/araC on the upstream of fimE.PBAD/araC_fimE (BBa_K1632013) can induce the expression of FimE(wild-type) in the presence of arabinose. We co-transformed a fim switch(wild-type)_gfp and a PBAD/araC_fim recombinase in the E. coli DH5alpha strain. We measured the fluorescence intensity of the cells induced by different concentraions of arabinose.
From the experimental results,our FimE inverted the fim switch[default ON](wild-type) from [ON] state to [OFF] state but did not invert the fim switch[default OFF](wild-type) from the [OFF] state, dependent on the concentration of arabinose.
