Multiple sequence alignment.

<p>ClustalW alignment of the protein sequences of the major outer membrane protein (MOMP) from <i>C. pneumoniae</i> and members of the genus <i>Chlamydophila.</i> The solid boxes show the motifs putatively involved in substrate transport and selection. The pairwise percentage identity, to MOMP from <i>C. pneumoniae,</i> is indicated in parenthesis for each sequence. The dashed boxes show the four MOMP-derived peptides, as predicted using on-line epitope mapping prediction servers.
