BIOBRICK IMPROVEMENTS

dCas9-ω

dCa9s-ω is our main tool to build our project in E. coli. This catalytically dead Cas9 fused to the RNA polymerase ω subunit can act as an activator or as an inhibitor when provided the right guide RNA.

BBa_K1723000

PAM rich URS J23117 promoter

This promoter is composed of the weak J23117 promoter, BBa_J23117, fused to a PAM rich upstream regulatory region (URS) that is needed for dCas9 to bind as dCas9 cannot bind without a PAM sequence.

BBa_K1723001

PAM rich URS J23117Alt promoter

This promoter was made on the same template as PAM rich URS J23117 promoter, but was mutated to obtain different sequences for sgRNA targeting. It is also fused to a PAM rich upstream regulatory region (URS) that is needed for dCas9 to bind, as dCas9 cannot bind without a PAM sequence.
