| Type | conformation (handedness) | Nres | Total | Per res | Total | Per res | Nhb | Hydrogen bonds |
| α | α-Helix (RH) | 8 | 24 | 3 | 16 | 2( φ, ψ ) | 4 | i → i − 4 |
| β | 314-helix (LH) | 6 | 24 | 4 | 18 | 3( φ, θ, ψ ) | 4 | i → i + 2 |
Nres is the number of residues, Nbb is the number of backbone atoms, Ndof is the number of torsional-angle degrees of freedom, Nhb is the number of backbone hydrogen bonds, and i is the residue sequence number.
