Design Notes

This part was synthesized on the model of the PAM rich URS J23117 promoter (BBa_K1723001). The promoter BBa_K1723001 was mutated to change the sequences of the sgRNA-targeted sites therefore allowing the presence of two independently regulated promoters. We avoided mutating -35 sequence and -10 sequence to keep a similar promoter strength [1]. the new targeted sequences were generated randomly and blasted on E. coli genome to avoid unwanted interactions. Using this procedure we believe more similar promoters could be made. In our experiments the promoter is 40bp upstream of the ATG start codon.
