Sequence alignment of the β domains of SPATEs and B. pertussis autotransporters. The sequences of selected SPATEs and B. pertussis autotransporters were aligned using the DNAStar MegAlign program (ClustalW method). Amino acids that are identical to the corresponding EspP residues are highlighted in black. The arrow shows the passenger domain cleavage site. Mutations introduced into EspP at positions denoted with an asterisk impaired passenger domain cleavage, whereas those denoted with a filled circle did not.
