Kill switch
To the circuit a kill switch is added for two reasons: bio-safety and secretion. The bio-safety concern is that the E.coli is in essence a treat to the humans and thus it is killed after it has done what it is supposed to. The second reason is the efficient secretion: if the peptides are not secreted naturally it is very difficult to force them. The solution is cell lysis, then all the peptides will surely be secreted.
For lysis cassettes several options are already in the part registry, these are listed in the part registry. From these options the holin with endolysin kill switch, BBa_K112808, has the most experience and good experience. Furthermore, it is easy to combine with the other parts of the circuit.
In Figure 1 the kill switch is shown in the circuit. The kill switch gets activated after the timer, the final promoter is the PcI promoter. So, at the same time as the
