Sequence alignment and secondary-structure consensus prediction for RnQV1 P2 and P4 CP amino acid sequences. The sequences of P2 (1,356 amino acids for W1075; 1,357 amino acids for W1118) (A) and P4 (1,061 amino acids for W1075; 1,059 amino acids for W1118) (B) were obtained from the UniProt database [H1ACC6, M1VMJ0, H1ACC8, and M1VHN2, respectively). Several SSE prediction methods (PsiPred, Jnet, Porter, Sable, Gor, Yaspin, and Profsec) were used to test correlation with our models of the structural subunits. A consensus SSE prediction was obtained by simple majority at each sequence position. Identical residues (white on red background) and partially conserved residues (red) are indicated. The arrows indicate β-strands, and the spirals indicate α-helices.
