Figure 1. An example of data transformation for clarity of perception. A. Actual distribution of pI and MW values obtained for the P06761 protein of map 4. B. The comparison diagram transformed by pI values. Here and in below, the following legend is used: Current position of points on the map (row 1); Alignment of points according to the putative unmodified proteoform (row 2); Alignment of points according to the best match of δpI values (row 3); Prediction of pI values for proteins with different numbers (from 1 to maximum) of phosphorylated residues (row 5), acetylation sites (row 6), and succinylation sites (row 7); Combination of acetylation and phosphorylation (from 1 to maximum) (row 8); Combination of succinylation and phosphorylation (from 1 to maximum) (row 9); Combination of acetylation, succinylation and phosphorylation (from 1 to maximum) (row 10); Average values for multiples of phosphorylated residues from 1 to 15 (row 11).
