Usage and Biology
blaPEDO-1, a new carbapenem-hydrolyzing beta-lactamases, this enzyme has not yet emerged in clinical settings but constitute potential carbap- enem resistance determinants in pathogenic bacterial species, as demonstrated by their ability to confer resistance to ampi- cillin and various cephalosporins, as well as reduced suscepti- bility to carbapenems, once expressed in E. coli.

Molecular cloning
First, we used the vector pGEX-6p-1 to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
