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
