FIG. 3.

Amino acid sequences derived from the nucleotide sequences of PCR amplicons obtained with the D1-D3 primers in polymorphism groups II, III, and IV. The amino acid sequences are aligned to the corresponding sequences of the D1, D2, and D3 motifs (D1-3) of FnBPA and FnBPB from S. aureus 8325-4. Amino acids that differ from either the FnBPA or FnBPB proteins of S. aureus 8325-4 are designated in bold lowercase letters. The identities of the D1, D2, and D3 motifs of the FnBP adhesins from S. aureus 8325-4 are indicated in parentheses on the right.
