Description
At elevated temperatures, the U10 thermosensor releases its hairpin structure and allows the RBS to be readily accessible to the ribosome, enabling increased expression of our desired gene. The U10 thermosensor mainly exhibits activity at approximately 37˚C. Other temperatures such as 22˚C and 30˚C show very low gene expression levels. We picked U10 because of its higher specificity as a thermosensor in our chosen temperature ranges (22˚C - 37˚C). We did not make any modifications to the thermosensor genetic sequences given by Neupert, J., Karcher, D., and Bock, R.
Notes
Removed 2 BsaI restriction sites. Under 2 kb for synthesis by DNA 2.0.
