Distinct differences in several biophysical characteristics between POFs and PDFs. A comparison of PDFs and POFs shows distinct differences in several biophysical characteristics (S. cerevisiae, Sc; S. pombe, Sp; A. thaliana, At; O. sativa, Os; D. melanogaster, Dm; A. gambiae, Ag; M. musculus, Mm; R. norvegicus, Rn; H. sapiens, Hs; C. elegans, Ce). (a) Average length of PDFs and POFs from different species. (b) Structural disorder index (disorder/length) of PDFs and POFs from different species. (c) Hydrophilic index of PDFs and POFs from different species. Proteomes analyses were performed as described in Materials and methods.
