Design Notes

This part contains a dcas9 coding sequence under constitutive expression of a strong clostridial promoter Pcac_thl, itself characterised in the following part BBa_K2715001. It also contains the regulatory region and promoter for Toxin A, driving expression of the reporter gene gusA, and has the alternative sigma factor required for activity of the promoter under control of the clostridial ferredoxin promoter, itself characterised in the following part BBa_K2715002. Each of these 3 modules are separated by a terminator sequence BBa_K2715014 , in order to represent read-through of the strong promoters into the native Toxin A promoter. The composite module is not RFC10 compatible because the dCas protein that we used contains restriction sites, we are not physically submitting this module but we do use it for experiments demonstrated on the wiki.


Source

The dcas9 is from S. pyrogenes, the promoter is from C. acetobutylicum, the toxin A regulatory regions including TcdR are from C. difficile, and the GusA protein is taken from E. coli.
