Our project pertains to measuring concentrations of fluoride and characterizing fluoride riboswitches with higher affinity to fluoride; these technologies can be used to determine methods to sequester, bioremediate, and detect fluoride.
We developed the "Fluoride Riboswitch Regulated Chloramphenicol Acetyltransferase Operon" (CHOP) regulated by the fluoride riboswitch as a system to characterize the fluoride riboswitch.
Since bacteria does not grow in the presence of chloramphenicol, the protein bacteria needs the chloramphenicol acetyltransferase protein in order to grow on chloramphenicol. We plated serial dilutions of CHOP and ΔcrcB, which is our control E.coli without the resistance to chloramphenicol, onto plates with varying concentrations of fluoride in order to test the best level the fluoride that CHOP can stimulate growth.
Our results demonstrated that with no fluoride there was no growth of CHOP. However, the growth of CHOP increased as the concentration of fluoride increased. In other words, CHOP is fluoride dependent. Our fluoride riboswitch was able to regulate the expression of chloramphenicol acetyltransferase as judged by bacterial growth; the concentration with the most growth of CHOP would represent the best activation concentration of fluoride for the riboswitch. Since the growth of bacteria containing the CHOP vector is correlated with the activation of the fluoride riboswitch, CHOP can be used to find other riboswitches that have a better affinity to fluoride, by screening for fluoride-dependent bacterial growth at lower concentrations of fluoride.
