  • a Solvent-exposed residues are shown above the diagonal, and structural residues are shown below the diagonal.

  • b Col-E and Col-G are highly similar but significantly diverge in their LRR-encoded DNA sequences from the rest of the family; as a consequence, the Ka/Ks analysis did not produce meaningful results (denoted by dashes).
