Universal DFT accumulation in proteomes.

Probability of a number of DFT in a protein, on log-log scale, for 32 eukaryotes proteomes, colored differently for Animalia (red), Plantae (green) and Fungi (yellow). Few FTs occur quite often in the proteome while many FTs are rare. The cases of human and E. coli are shown as specific examples. All individual eukaryote species are very well fitted by a pure power-law (see Text S1 - section 9). E. coli serves as an example of a typical prokaryote.
