Bacterial Thermometer

We want to create an RNA-based system that is able to have differential gene expression when temperature changes take place (kind of similar to the Berkeley iGEM 2006 - riboregulator lock/key part [1]).

There are several systems suggested in literature that are based on RNA secondary structure. The idea in general is that if the temperature drops below a certain temperature, the RNA will form stable base-pairs on the Shine-Dalgarno sequence, disabling the ribosome to bind. The base-pairing of this RNA region will block the expression of the protein encoded behind it. In this way gene expression can be regulated on the RNA level by temperature.
