Multiple alignment of the partial amino acid sequences of the two putative metallo-β-lactamases in L. hongkongensis and those of known metallo-β-lactamases showing the conserved zinc-ligand binding sites. Amino acid residues high-lighted in yellow and blue representing two independent putative zinc-ligand binding sites of class B3 metallo-β-lactamase His116-His118-His196 and Asp120-His121-His263. Numbers in parentheses indicate the corresponding positions in the amino acid sequences. L1, Stenotrophomonas maltophilia IID1275 (accession no. CAA52968); FEZ-1, Legionella gormanii ATCC33297 (accession no. CAB96921); CAU-1, Caulobacter vibrioides DSM 4727 (accession no. CAC87665); BJP-1, Bradyrhizobium japonicum USDA 110 (accession no. NP_772870)
