  1. Results of a protein database search. Similar sequences from human proteins, bacterial and fungal proteins are shown. Each peptide bears the HLA-B27 binding motif at least at position two (arginine). Identical amino acids are shaded, conserved substitutions are underlined. A standard search in SWISS PROTEIN database was performed using the TFASTA program (24).
