Design Notes
This is a composite part constructed to express a synthetic guide RNA designed to work with the dCas9 protein from S. pyrogenes. It is composed of the previously used constitutive E. coli promoter BBa_J23119, a unique 20 bp guide targeting sequence BBa_K2715035, a synthetic guide RNA for S. pyrogenes dCas9 protein BBa_K2715042, and a terminator sequence BBa_K2284000.
Source
The promoter J23119 is present in pSB1A2 and sourced from the iGEM registry, the unique guide sequence is sourced from the promoter region of toxin A from C. difficile. The synthetic guide RNA sequence is sourced from the CRISPR vector described in CRISPR/Cas9-based efficient genome editing in Clostridium ljungdahlii, an autotrophic gas-fermenting bacterium. ACS synthetic biology, 5(12), pp.1355-1361 (see refs below). The terminator is sourced from the pMTL80000 modular vector series developed by the SBRC Nottingham (see refs below).
