target sequence upstream of promotor

To facilitate measurements, we used a reporter plasmid, with the mRFP gene under the control of a weak promoter (BBa_J23117) that is preceded by a sequence rich in NGG PAM sequences on the NT strand.

We designed sgRNA that complements the NT strand from at least 20nt upstream from -55 point (With the transcription start denoted +1, RNAP complex covers from -55 to +20.)

When the dcas9-sgRNA complex binds to target sequence, RpoA will recruits RNA polymerase, promotor J23117 will be activated. Then, by measuring the biological activity of the downstream reporter gene, we will know the effectiveness of this transcription activation device under different conditions.
