Backbone dihedral angle. Backbone dihedral angle distributions (a) for the antiparallel (A1 & A2) and parallel (P1 & P2) β-sheets at the amphipathic interface of the lipid bilayer, and (b) for the antiparallel (A1) and parallel (P1) β-sheets in water. Dihedral angles (φ, ψ) are calculated only for the residues in the β-strands (residues 4 to 8 and 13 to 17 of each β-hairpin).
