Amino acid alignment by the Lipmann-Pearson (DNA Star program) method of the neuA gene regions of two L. pneumophila strains, L. longbeachae NSW150, and five other bacterial species showing regions of high similarity (>6 amino acids): Carboxydibrachium pacificum DSM 12653 (accession number ABXP01000000; identity, 40%), Desulfomicrobium baculatum DSM 4028 (accession number NC_013173; identity, 43%), Geobacter lovleyi (accession number NC_01081; identity, 38%), E. coli 55989 (accession number NC_011748; identity, 34%), and N. meningitidis ATCC 13091 (accession number AEEF01000113; identity, 38%). In the sequences, periods indicate residues that differ from the sequence of Philadelphia-1.
