RNA thermometer (ROSE 32°C)

An [http://2008.igem.org/Team:TUDelft/Temperature_analysis#RNA_thermometer RNA thermometer] which can be used for temperature sensitive post-transcriptional regulation, and which is designed to initiate translation around 32°C.

The image shows the secondary structure of the part after ligation to a protein coding part, as predicted by [http://rna.tbi.univie.ac.at/cgi-bin/RNAfold.cgi RNAfold]. Notice that the 3' end, including the scar and the start codon, does not belong to the part. The blue region is the Shine Dalgarno sequence which is the ribosome binding site.

Characterization

To characterize this RNA thermometer in vivo, we made an RNA thermometer testing circuit, transformed it into E. coli, and tested the fluorescent output at different temperatures. These graphs show the relative fluorescent intensity of each thermometer between either 25 °C and 30 °C or 25 °C and 37 °C
