Part:BBa_I716462

{AraC-Pbad}{rbs1-A}{ATG}{BamHI no ATG}

Part I716462 was previously characterized by the UC Berkeley iGEM team in 2007. The purpose of this part was to prevent unwanted cell proliferation by engineering a genetic self-destruct mechanism into bacteria that upon induction would express a genetic material-degrading toxin, the endonuclease BamHI that would kill cells yet preserve their physical integrity. BamHI has a restriction cut site of G'GATCC, generating sticky ends (1). The restriction endonuclease was placed under the control of the arabinose- inducible promoter, pBAD. In 2007, the UC Berkeley iGEM team was able to show that cells lost their ability to reproduce but did not lyse upon induction with arabinose (2). The University of Lethbridge 2011 iGEM team wished to further characterize this part to degrade the genomic DNA of E. coli in order to have a functional chassis for our tailings pond clean-up kit without the risk of DNA contamination. In this way, tight control and regulation over our engineered bacterial cells is possible.
