T7 promoter+RBS b+Linker h+His+Linker f+GIM-2+T7 terminator
This part consists of T7 promoter, RBS and protein coding sequence(His+Linker f+GIM-2),and the biological module can be built into E.coli for protein expression.

Usage and Biology
This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS ,Linker h ,Linker f,T7 terminatorand and our target protein GIM-2. It encodes a protein which is GIM-2 fused with His tag. Linker h is from the vector pET-28a, which connects the RBS to His tag sequence.Linker f from vector pGEX-6p-1, contains the thrombin restriction site and T7 tag.The fusion protein is about 27.4 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of GIM-2. It is convenient for us to purify our target protein.
Molecular cloning
First, we used the vector pGEX-28a to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
