Figure 3. Arteriviridae:
Amino acid sequence alignments are provided separately for each of the five domains (nsp5-3CLpro, nsp12-NiRAN, nsp12-RdRp, nsp13-ZBD and nsp13-HEL1) used in the DEmARC analysis presented in Figure 3. Arteriviridae. An additional alignment comprises a concatenation of these domains, each separated by four spaces. Phylogenetic analysis of the concatenated alignment gives a tree with a similar topology to that shown in Figure 3. Arteriviridae, but differs in detail because the DEmARC analysis included additional nidovirus sequences and involved model testing using individual domains.
