Comparison of Pth to Pfs.

The table lists for several peptides, polypeptides, and proteins their length (L), percolation threshold (Pth), proportion of functional sequences (Pfs), and the ratio of the percolation threshold to the proportion of functional sequences (Rb). It also lists the minimum allowed number of mutations between neighboring sequences (nmin) for Pth to approximate or drop below Pfs. The nmin values were converted to sequence identities (SI) using Eq 4. The study that reported a Pfs value is cited next to the protein’s name. Proteins are listed in order of descending Pfs.
