Changes to properties of amino acids caused by mutations. Average changes per residue in residue volumes when comparing original amino acid and mutated amino acid in A) α-helices, β-strands, turns and bends and B) separately in α-helices (H), 3₁₀-helices (G), extended strands (E), isolated β-bridges (B), turns (T) and bends (S). C) Average changes per residue in charges when comparing original amino acid and mutated amino acid in α-helices, β-strands, turns and bends and D) separately in α-helices, 3₁₀-helices, extended strands, isolated β-bridges, turns and bends.
