RBS a+Linker g+GST+Linker e+GIM-2

This part consists of RBS a, protein coding sequence(GST+Linker e+GIM-2), the RBS and the protein coding sequence can be connected by linker g. 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.

Sequence and Features

Usage and Biology

This composite part is made up with five basic parts, the RBSa, the linker g and the GST tag, the cutting site of Prescission Protease and our target protein GIM-2. It encodes a protein which is GIM-2 fused with GST tag. The fusion protein is about 53.4 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of GIM-2 and combine the two parts with the cutting site of Prescission Protease. The fusion protein can be cut off at the cutting site by Prescission Protease. It is convenient for us to purify our target protein.
