Classification of Complete Proteomes of Different Organisms and Protein Sets Based on Their Protein Distributions in Terms of Some Key Attributes of Proteins

Figure 2

Protein distributions for the human (H. sapiens) proteome in the LD space defined by ln(L) (the protein length in a logarithm scale) and ID (protein intrinsic disorder contents with 1.0 corresponding to proteins with 100% residues disordered and 0.0 corresponding to proteins with 0% residues disordered). The distributions in the hierarchical scale are shown in (b) and (c), respectively (see text). Linear fittings of ln(L) and ID are shown in red dashed lines with satisfactory R² and hence support the linear participations shown in Table 2. The blue and red dots indicate the shortest (16 aa) and longest (34,350 aa) proteins, respectively.
