Figure 6

Comparison between the MTase-GTase Core of the noda and chropara groups. Conventions are the same as in Figures 2 and 3. Numbering of secondary elements is as for the alphavirus supergroup, and by analogy, the Core region ends at the position W/Y/F♦ in strand βG. The sequences of the chropara group were aligned to the set alignment of the noda group by using MAFFT with the --add option [94]. Conserved cysteines in the chropara group, which may be equivalent to those of the alto group, are indicated by an asterisk. The putative equivalent of the conserved D♥ of the alphavirus supergroup is boxed with a dashed line.
