Figure 2.

Partial sequence alignments of the B protein from exinuclease ABC complex (A) and phenylalanyl-tRNA synthetase (B) showing two conserved indels that are specific for ε-Proteobacteria and not found in other organisms. The dashes (-) in the alignment show identity with the amino acid on the top line. The accession numbers of the sequences (second column) and position of the sequence in C. jejuni homolog (on top) are indicated. Sequence information for only representative species is shown.
