A range is defined as the length between two residues along a given sequence, i.e., a range is defined as M = 1 when 1 ≦ k≦ 8 where k = |i-j| and i and j are the residues numbers along the sequence. In the same way, 9 ≦ k ≦ 20, 21 ≦ k ≦ 30, 31 ≦ k ≦ 40 and so on define respective ranges M = 2, 3, 4 ···. The average distances between C atoms of residues were calculated in each range using proteins with known structures.
