Statistical investigations of protein residue direct couplings
Fig 3
S, SF and PPV scores as a function of various 3D structural coordinates for each of five protein domains.
Structures are ordered by the average of their scores over four methods: CCM (black lines), EVC (cyan lines), GSF (red lines) and PCV (green lines). Below the name for each domain are shown both the mean value of F and of the optimal cut points X for the S-scores. The constant cut point values of x = F × ℓ are shown between the PPV and SF plots. The value of r (the maximum 3D distance defining contacting pairs) is 5 Å.
