Design Notes

Original vector: pHT315

This shuttle vector is derived from pHT315. The complete sequence of pHT315 has been published, as well as the construction of pHT304 in "Construction of cloning vectors for Bacillus thuringiensis (Arantes O. & Lereclus D., 1991 Gene[1]"). The E. coli origin comes from pUC19 and the Bacillus origin from pHT1035. The newly constructed plasmid was modified so that the final construct (pHT315) would not have any restriction site duplicated.

Construction of BBa_K802004

The pHT304 shuttle vector contains all 4 of the iGEM sites. The gel electrophoresis showed that all of them are unique sites. Given the fact that the polylinker from pHT315 is the same one from pUC19, we know that the sites EcoRI, XbaI and PstI are in the polylinker and not in a coding region of the plasmid. However, the SpeI site was not in the polylinker. A double digestion by EcoRI and SpeI gave two fragments of 1 kb and 5.5 kb. At a closer look at the Bacillus region coming from the pHT1035-15△HindIII plasmid (i.e. the pHT1035 after the deletion of the site HindIII and after the selection of a high copy number plasmid based on the antibiotic concentration), we identified the SpeI site. Fortunately, the site was neither in the origin of replication for Bacillus, nor in the gene responsible for the Erythromycin resistance. The site SpeI was eliminated by filling-in [2). Afterwards, a customized iGEM polylinker [3] containing all 4 of the iGEM sites in the right order was cloned in EcoRI and HindII sites of the shuttle vector.

The plasmid is derived from the pHT315 vector (Arantes and Lereclus, 1991).
