Previosuly, Olga et al (2011) described a temperature dependent riboswitch involved in regulating bacterial chemotaxis at high temperature (Fig 1A). They reported that the mRNA carrying the riboswitch was stable at all temperatures however, the protein expression was favored only at low temperature indicating a robustness in regulating bacterial chemotaxis (Fig 1B and Fig 1C).

We believe that this low-temperature dependent riboswitch would be of great interest in heterologous protein expression. Favoring expression only at a low temperature would gurantee that the heterologous proteins are folded properly without the formation of inclusion bodies.
