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 is 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 K2276010 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_K2276010 has a much strong expression than Part: BBa_I13521.

fig.1The fluorescence intensity changes over time (0h~16h). P1 represent the strain containing part: BBa_K2276007. P2 represent the strain containing part: BBa_K2276008. P3 represent the strain containing part: BBa_K2276010. TetR represent the strain that only has tetR repressible promoter without RBS and protein coding sequence. B0034 represent the strain that containing Part: BBa_I13521.
fig.2 The OD600 changes over time(0~16 h).P1 represent the strain containing part: BBa_K2276007. P2 represent the strain containing part: BBa_K2276008. P3 represent the strain containing part: BBa_K2276010. TetR represent the strain that only has tetR repressible promoter without RBS and protein coding sequence. B0034 represent the strain that containing Part: BBa_I13521.
