Part:BBa_K2922034

The colicin-N operon under T7 promoter control

Summary

This is a composite part consist of a T7 promoter (BBa_K525998), CDS of colicin-N (BBa_K2922027), CDS of colicin-N immunity protein (BBa_K2922028) and CDS of lysis protein (BBa_K2922029). Each CDS has an RBS (BBa_B0034) behind. T7 promoter could be induced by IPTG or lactose in Escherichia coli BL21 strain and then express all proteins mentioned. E coli that can`t express colicin-N immunity protein would be killed by colicin-N, colicin-N immunity protein is used to protect itself from attack of extracellular colicin-N and lysis protein helps the release of colicin-N. This part is constructed in the aim of achieve our “aggressive” design.

Ientification

To build this part correctly, Agarose gel electrophoresis is used to examine and strands in correct length are extracted to sequence for further examination.
