RNA Thermometer rpoH

In nature, rpoH is implemented in the mRNA structure of a Escherichia coli heatshock gene which is important for stress tolerance. The thermometer is a structural element that is located within the 5’ UTR of protein-coding mRNA. It operates as a reversible molecular zipper that controls the availability of the RBS in its structure. When the temperature increases, the thermometer unzips and the RBS can be detected by the ribosome thus allowing translation of downstream mRNA. When the temperature is below a certain range, the RBS gets trapped.
