Part:BBa_K533012

safety version of pSB1C3 plasmid

All ccdb parts have been withdrawn from the Registry. Samples of parts containing the ccdB gene cannot be requested. - iGEM HQ

The plasmid has a ccdB suicide gene and a mutation-controller sequence, variant of I-SceI restriction site. It can hence eliminate devious mutations and help to restrain biobricks to only our engineered organisms.

The variant of I-SceI site present in the plasmid allows for elimination of heavily mutated vectors in I-SceI expressing strains.

This year, we tried to construct an E. coli strain expressing ccdB resistance gene and I-SceI endonuclease from its chromosome and wanted to use this new strain as the engineering strain for all the biobricks. Due to the limited time, we did not construct this strain. Any teams interested in enhancing safety level might consider this undertaking.
