FIG. 4.

Alignment of the amino acid sequences of the putative collagen-binding subdomains of A. pyogenes CbpA, S. aureus Cna (GenBank accession no. M81736), E. faecalis Ace (GenBank accession no. AF260872), and E. faecium Acm (GenBank accession no. AY135217). Where three or more amino acids are identical, they are boxed in black. The five amino acids thought to be critical for collagen binding of Cna (39) are indicated by arrows. Amino acid numbers for each protein are on the right.
