The dependence of function divergence on sequence divergence for the EF-hand family in which the proteins with only the non-experimentally supported annotations were utilized. Abscissa; GO Distance; Ordinate; fraction of comparisons. Different colors show distributions of sets of pairs of proteins with different ranges of sequence similarity, divided into bins of width 10% residue identity.
