Pairwise amino acid alignment of the replication initiation protein from ΦCA82 (GenBank accession number HQ264138) and SpV4 (GenBank accession number NC_003438) microphages. Identical amino acids (*), residues with strong similarity (:), and weak similarity (.) are shown. Locations of conserved domains are boxed. The active sites of the rep protein are shaded gray.
