Figure 4. — Three-dimensional alignment of ElaOMV1 (light-brown) and ScNV-20S (light-purple) RNA-dependent RNA polymerases. Panel A shows the alignment at a low magnification level, so it is possible to see the alignment of the overall protein structures (they are shown as cartoons). Panel B shows the alignment at a higher magnification level: it is possible to see the alignment of the palm domain (green, red, and blue belong to ElaOMV1; light-green, light-red, and light-blue belong to ScNV-20S; structures are shown as ribbons). In Panel C, the focus is only on conserved amino acids part of the catalytic triad in palm domains A, B, and C.
