RBS b+Linker h+His+Linker a+Sumo+Linker b+TMB-2+T7 terminator
This part consists of RBS, protein coding sequence(His+Linker a+Sumo+Linker b+TMB-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
The Tripoli metallo-beta-lactamase-1 (TMB-1) gene was first discovered in a Achromobacter xylosoxidans strain obtained from an environmental sample in a hospital in Tripoli, Libya, in 2011
After the initial report, TMB-1 has been identified in clinical isolates of Acinetobacter spp. in Japan, and the new TMB-1 variant named TMB-2, with the single mutation S228P, was isolated from a different hospital in Japan also in clinical isolates of Acinetobacter spp.
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.
Figure 1. Left: The PCR result of TMB-2. Right: The verification results by enzyme digestion.
After verification, it was determined that the construction is successful. We converted the plasmid to E. coli BL21(DE3) for expression and purification.
