FIG. 3.

Multiple alignment of C. pneumoniae Omp4 and Omp5 and C. psittaci Pomp98 (27). Amino acid sequence alignment was done with the PILEUP program (GCG 8.1 package). Dots represent gaps, the black areas indicate amino acid identity, and the grey areas indicate amino acid similarity. The repeated amino acid motifs are boxed. The arrow shows the putative signal peptidase II cleavage sites in C. pneumoniae Omp4 and Omp5. The beginnings and ends of peptides expressed from the pEX clones are indicated by boxes (pEX3-36), asterisks (pEX1-1), and triangles (pEX2-10), respectively.
