Various measures of intrinsic disorder content in 53 species: (a), Ratio of disordered residues in each species; (b), Percentage of proteins with long disordered regions (>30aa) in each species; (c), Ratio of fully disordered proteins in each species. In all figures above, the X-axis is the index number of each species. Filled squares indicate the taxonomy of archaea with similar species together and on the same level. (1), (3)-(5) indicate species in four phyla: Crenarchaeota, Korarchaeota, Nanoarcgaeota, and Thaumarchaeota. (2.1) - (2.8) are eight different classes in the phylum of Euryarchaeota. (d), Correlation among various disordered contents. X-axis: the ratio of disordered residues. Y-axis: percentage of proteins with long disordered regions and percentage of fully disordered proteins, accordingly.
