FIG. 4.

Alignment of amino acid sequences for the coat protein (CP), N-proximal minor coat protein (nCPm), and C-proximal minor coat protein (cCPm) of the criniviruses LIYV and SPCSV. The numbers of the first and the last amino acids shown in the alignment are indicated, and an asterisk indicates the end of the protein. Gaps between sequences (marked with dots) indicate adjoining sequences and are due to the alignment program. Conserved residues in each pairwise alignment are indicated in bold. Residues conserved in all sequences are highlighted by shading, and the S, R, and D residues conserved in all filamentous plant virus CPs are also indicated by an exclamation mark. Consensus (Cons.) indicates the similar or identical amino acid residues for the CP sequences (above the alignment) or the cCPm sequences (below the alignment). The amino acids that were similar or identical in the CP and cCPm sequences are indicated between the alignments. In the consensus: a, an acidic residue (D or E); b, a basic residue (H, K, or R); f, a hydrophobic residue (A, F, I, L, M, P, V, or W); o, an aromatic residue (F, W, or Y); p, a polar residue (C, G, N, Q, S, T, or Y).
