We choose four different promoters whose reported strengths are respectively low, medium,strong and the strongest from constitutive promoter family to express the inhibitor tetR and cI ,and then we construct three plasmid with different copy number containing this circuit, in order to find out the proper promoter which meets the threshold that trigger the killer system.

<Description>
This is one of our application circuits.


This circuit contains two devices: inhibitor device and killer device.
Inhibitor device: We select strong constitutive promoter J23119 and strong RBS B0034 to express inhibitor gene tetR.
Killer device: Toxin protein, MazF, can cleavage ACA sequence of free mRNA specifically. It cause bacteria can’t translate successfully and dead finally. So we constructed it with induced promoter pTet and medium RBS B0032 to control the expression level of toxin protein.
We reversed the direction of inhibitor device, in order to reduce the influence between two devices.
Meanwhile, we also constructed more circuits which have different combine with promoter, RBS and inhibitor. More detail see in our Wiki([http://2016.igem.org/Team:BIT-China/Parts Parts Submission])
