Fluoride riboswitch
We also plan on implementing and characterising a Fluoride riboswitch. This, unlike the Magnesium construct, is a positive regulator. The riboswitch, originally isolated from Bacillus cereus, serves as a transcriptional attenuator in the abscence of fluoride. In the presence of fluoride its conformation changes and the repression is lifted. In B. cereus this serves to permit translation of a fluoride efflux pump, which allows the bacteria to cope with the, potentially toxic, elevated fluoride levels in which it finds itself.
