Figure 6.

An example of an indel being flanked by divergent regions in Methanopyrus kandleri. The portion of the alignment corresponds to positions 1,281 to 1,340 in our RNA polymerase subunit A' dataset. For clarity, identical amino acids shared by each taxon and the first taxon (Sulfolobus tokodaii) are indicated by dashes, whereas stars correspond to missing amino acids.
