Figure 4

The values of the ν parameter reflecting changes in amino acid frequencies for different evolutionary tree branches for categorizations based on the van der Waals volume, hydropathy and isoelectric point. y-axis, amino acid groups (see Table 4); x-axis, v (see Methods section); branches are labeled as in Figure 2. Property designations: A, van der Waals volume; B, hydropathy; C, isoelectric point.
