T7 promoter+RBS b+linker h+His+Linker a+Sumo+Linker b+TMB-2+T7 terminator

The part consists of T7 promoter,RBS and protein coding(His+Linker a+Sumo+Linker b+TMB-2)and the biological module can be built into E.coil for protein expression.

Usage and Biology

This composite part is made up with nine basic parts, T7 promoter, the RBS b， the linker h， His tag，the linker a, Sumo tag, linker b, the gene of TMB-2 and T7 terminator.It encodes a protein which is TMB-2 fused with His and Sumo tag. The fusion protein is about 39.2 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of TMB-2 and combine Sumo tag to increased protein solubility. The fusion protein can be cut off at the cutting site by Prescission Protease. It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pGEX-6p-1 and pET-28b_SUMO to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
