(A) Alignment of amino acid sequences of RSV-A strains in the second variable region of G protein. Alignments are shown relative to the sequence of ON1 strain first described in Canada (GenBank accession number JN257693). Alignment of sequences was performed using the ClustalW1.6 method via BioEdit software. The amino acid positions correspond to positions 210 to 322 of the G protein of the ON1 strain. Identical residues are indicated by dots, asterisks indicate the position of stop codons. Dashed line boxes frame the 23 amino acid duplicated region of the 24 amino acid insertion. Solid line boxes highlight predicted N-glycosylation sites. This study RSVA strains are labeled with their NCBI accession numbers. (B) Alignment of amino acid sequences of RSV-B strains in the second variable region of G protein. Alignments are shown relative to the sequence of a prototype BA strain (GenBank accession number AY333364). Alignment of sequences was performed using the ClustalW1.6 method via BioEdit software. The amino acid positions correspond to positions 201 to 313 of the G protein of the BA strain. Identical residues are indicated by dots, asterisks indicate the position of stop codons. Dashed line boxes frame the 20 amino acid duplication and insertion. Solid line box highlights predicted N-glycosylation sites. This study RSV-B strains are labeled with their NCBI accession numbers
