===Design Notes===

This part was designed to fulfill the self destruct system of P.A.S.E 1. It contains a toxin system based on phage lysis system of holin (BBa_K112805) and lysozyme (BBa_K112301). Holin protein causes "pores" in the inner membrane, which allows lysozyme to access and break down the peptidoglycan of the cell wall, causing lysis and eventually death. The toxins are regulated by cI regulated promoter (BBa_R0051). This part is designed to integrate into the cell's genome via homologous recombination and therefore it contains homologous regions at its ends. Kanamycin resistance was added for selectivity. Therefore, when transforming in bacteria only the cells that have gone through double recombination with the insert will survive.

P.A.S.E. 1 cassette

A DNA cassette that undergo homologous recombination into E.coli genome that contains homologous regions at each end, Kanamicin resistance gene (KanR) and death operon containing Lambda holin and lysozime genes and controlled by a Lambda cI regulated promoter
