Frequency of protein structure elements. Box plot representation of protein secondary structure elements in 81 structures. L = 317 ± 20 (mean ± SEM, n = 81). Secondary structure codes: H, alpha helix; B, residue in isolated beta bridge; E, extended strand, participates in beta ladder; G, 3-helix (3/10 helix); I, 5 helix (pi helix); P, polyproline type II helix (left-handed); T, hydrogen bonded turn; S, bend.
