PAM rich URS j23117 promoter

PAM rich URS J23117 is an improvement of the J23117 (BBa_J23117) weak promoter [1]. This promoter is the promoter J23117 flanked with a PAM (PAM = NGG sequence) rich Upstream Regulatory Sequence (URS) to enable the use of protein dCas9-ω (BBa_K1723000) as a gene transcription regulator when in complex with one sgRNA targeting the promoter such as: the activator sgRNA Z4 (BBa_K1723003), the inhibitor sgRNA Z0 (BBa_K1723002), or the other inhibitor sgRNA Z35 (BBa_K1723004). dCas9 can only bind if the DNA target sequence is preceded by a PAM sequence.
