FIG. 1.

Central unglycosylated region of the RSV G protein. Residues 151 to 190 of the RGH subtype A5 RSV strain and those from the prototypical subtype A (A2) and B (B1) strains are identified. The positions of relevant residues are shown by numbers above the amino acid alignment. Note that invariant residues 164 to 176 are shown in bold, and the predicted disulfide bonds are shown as solid lines connecting the relevant cysteine residues. The dotted line underlies residues 151 to 172 (the PCC; see the text) bearing the epitopes for L9 and K6 MAbs.
