Figure 1. Sequence of the Chilean HpaA clone 5 and comparison with HpaA sequences from strains 26695, J99, CCUG 17874 and 8826.
Conserved amino acid residues are indicated by asterisks (*), deleted positions by dashes (-), and the differences in the HpaA sequence of strain CH-CTX1 are in bold face. The conserved receptor-binding motif is underlined.
