Alignment of the predicted amino acid sequence of the ICMP3153 symbiotic element integrase (3153 int) with sequences of some other members of the P4 integrase family: φR73 int, retronphage phi-R73 integrase (A42465); φSF6 int, Shigella flexneri phage Sf6 integrase (X59553); SlpA int, SlpA integrase from cryptic E. coli phage CP-57 (U36840); V. chol int, tcp-associated integrase from V. cholerae (U39068); D. nodo int, vap-associated integrase IntA from Dichelobacter nodosus (L31763). Identical amino acid residues are shaded.
