RBS b+Linker h+His+Linker a+Sumo+Linker b+GIM-2+T7 terminator

This part consists of RBS, protein coding sequence(His+Linker a+Sumo+Linker b+GIM-2) and T7 terminator,and the biological module can be build into E.coli for protein expression. This part can be prefaced with promoters of different strengths and types to regulate expression function.

Usage and Biology

This composite part is made up with eight basic parts, T7 Ribosome binding sites,the His-Sumo tag, three cutting sites of Prescission Protease, our target protein GIM-2 and T7 terminator. It encodes a protein which is GIM-2 fused with His-Sumo tag. The fusion protein is about 39.4 kD. The fusion protein can be cut off at the cutting sites by Prescission Protease. It is convenient for us to purify our target protein.
