Partition characteristics of two groups of proteins from 249 species based on the content of simple sequences present in them. The fraction of low complexity sequences in proteins was computed using SEG with the default parameters 45, K1 = 3.4, K2 = 3.75. Proteins with Fc < 15 (pink contour) have lower fraction of low complexity sequences whereas proteins with Fc ≥ 15 (blue contour) have higher fraction of simple sequences. Note that the peaks appear at the extremes. The proportion of proteins in the Y-axis is computed in the respective datasets. For example, the proportion of proteins with a given fraction of low complexity sequence for pink contour is computed with respect to the total number of proteins with Fc < 15.
