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.
