T7 promoter+RBS b+Linker h+His+Linker f+PST-1+T7 terminator

This part consists of T7 promoter, RBS and protein coding sequence(His+Linker f+PST-1),and the biological module can be built into E.coli for protein expression.

Usage and Biology=

This composite part is made up with three basic parts, the His tag, T7 promoter, RBS and our target protein PST-1. It encodes a protein which is PST-1 fused with His tag. The fusion protein is about 26.2 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of PST-1. It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pGEX-6p-1 to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
