a composite of TetR repressible promoter、special designed RBS and the coding sequence of mRFP
The part was designed based on the Part: BBa_I13521, while the RBS binding site is modified. The RBS is special designed for strainS whose last 9 nucleotides of the 16S rRNA are ACCTCCTTA. And it can be regard as a improvement for it has a high translation rate compared with Part: BBa_I13521.The promoter is TetR repressible promoter which is also used in the repressilator system. And the mRFP served as the reporter to help us measure the translation rate of the designed RBS.

Measurement
We constructed strains that contain Part:BBa K2276007 and measure the fluorescence intensity and OD600 changes of it. Due to the limit of the experiment condition, we measure the change at the first 8hours and 10~16 hours after inoculated separately. As what Fig 1 and Fig 2 show,Part: BBa_K2276008 has a weaken expression than Part: BBa_I13521.
