Design Notes

Because this is a positive regulator (it ceases transcriptional termination in the presence of F- ions), it was decided that it should be placed upstream of a direct reporter. In this case, lacZ was used as our reporter. We have included the lysine promoter as part of this biobrick as a reliably constitutively active promoter, ensuring that the rate of transcription of downstream genes should only be affected by the rate of transcriptional attenuation by the fluoride riboswitch.
