Usage and Biology
MUS-2 is a novel variant of the chromosome-encoded β-lactamase MUS-1 in M. odoratimimus, which has been isolated from livestock animals in Lebanon. It could be sure that animals could be a reservoir for such genes and are a source of new and/or emerging multidrug-resistant bacteria and due to possible links with animals, humans may have high risk factors for colonization/infection with such bacteria. Bacteria that carry the enzyme are potentially harmful to humans.
Molecular cloning
We used the vector pGEX-6p-1 to construct our expression plasmid.
Figure 1. Left: The PCR result of MUS-2. Right: The verification results by enzyme digestion.
After verification, it was determined that the construction is successful.
