Phylogenetic tree obtained for clinical relevant MβLs and PAN-1 by distance method using neighbor-joining algorithm (SeaView version 4 software). Branch lengths are drawn to scale and are proportional to the number of amino acid substitutions with 500 bootstrap replications. The distance along the vertical axis has no significance. Percentage of amino acid identity shared with the PAN-1 enzyme is indicated in brackets. The tree is rooted with the KPC-2 enzyme.
