Only the fragment domain of the peptides is shown. Class 1 peptides are derived from peptide C (Table I) and the putative minimal epitope is underlined. Class 2 sequences contain portions of the ARRXA motif. Conserved residues are in bold. Sequences derived from parent peptides A and B, as well as new peptides D, E, and F, are labeled. The C-terminal RGQ in the sequence derived from peptide A is encoded by part of the 3’-constant region. Class 3 peptide sequences were aligned using CLUSTALW (http://npsa-pbil.ibcp.fr) with key residues determined automatically. Clone frequency (out of 20) is shown and differing residues are italicized as described in Table I. Peptide sequences translated from alternate start codons are marked (*).
