Meganuclease I-SceI controlled by pRha

I-SceI homing endonuclease expression is controlled by pRha promoter. Expression is induced with L-rhamnose. I-SceI doesn't have an LVA degradation tag.

Characterization

We performed a set of experiments to show I-SceI is expressed and active in eliminating restriction-site harbouring plasmid.

Experimental setup

We transformed two plasmids with different antibiotic resistances into NEB Turbo E.Coli strain:

1. First plasmid: Low copy plasmid with encoded generator to express I-SceI meganucllease. Three version with different promoters was tested: I-SceI meganuclease controlled by pBad, pLac and pRha. For all version:
   • Backbone: pSB3C5
   • Resistance: Chloramphenicol
   • Origin of Replication: p15a
2. Second plasmid: High copy plasmid with encoded I-SceI restriction site, K175027. This biobrick was a kind gift of the [http://2012.igem.org/Team:TU-Delft TUDelft iGEM team] which we further characterized.
   • Backbone: pSB1AK3
   • Resistance: Ampicillin and Kanamycin
   • Origin of Replication: modified pMB1 derived from pUC19

We expected to perform transformation with both plasmids, and plate with two antibiotics in order to select for double transformants. We would then induce I-SceI expression in those clones to measure its efficiency.
