A comparison of the paralogous genes of the Cpn 1054 gene family in Chlamydia pneumoniae CWL029. The 5' end of Cpn 1054 is similar to Cpn 008, 010, 011, 043,045, and 1055 while the 3' end was similar to the Cpn 009, 010.1, 012, 042, 044, 046, and 1056. The range of predicted amino acid similarity is 20–99%, as indicated by shading. Vertical bars indicate termination codons that interrupt the reading frame. The position of the beginning of each family member in the CWL029 genome is indicated above the sequence. All numbering is based on the CWL029 genome sequence .
