FIG. 6.
Comparison of the predicted protein characteristics from the amino acids of the p28 proteins of the Arkansas and Jax strains. Surface probability predicts the surface residues by using a window consisting of a hexapeptide. A surface residue is any residue with >2.0 nm2 of water-accessible surface area. A hexapeptide with a value of greater than 1 was considered as surface region. The antigenic index predicts potential antigenic determinants. The regions with a value above 0 are potential antigenic determinants. The T-cell motif locates the potential T-cell antigenic determinants by using a motif of five amino acids with residue 1 glycine or polar, residue 2 hydrophobic, residue 3 hydrophobic, residue 4 hydrophobic or proline, and residue 5 polar or glycine. The scale indicates the amino acid positions.
