Design Notes

In pSB1C3-LEE5*Δtir-gfp, the tir fragment was deleted so that the gfp start codon is at the position of the former tir start codon, which yielded BBa_K2688017. The introduced point mutation was then PCR corrected, yielding this biobrick.

Our results indicate that gfp expression is improved when this fragment is removed compared to the parental pSB1C3- LEE5*-gfp plasmid, and that H-NS protein is still able to control the remaining LEE5 region. Of note, Ler proteins are able to activate LEE5 promoter.



Source

LEE5 is a topic of research at the host lab, which provided us with the source plasmid pKK-LEE5-gfp.
