Amino acid alignment of five intimin sequences. Dots indicate identity to Int-θ, and dashes indicate alignment gaps. Consensus gaps indicate amino acid residues present in sequences that are not in those shown here. Shaded residues delineate the conserved central domain identified by McGraw et al. (23). Arrows demarcate the functional domains (20). GenBank accession numbers for previously published sequences are Int-α, AF022236; Int-β, AF081187; and Int-γ, AF081182.
