Backbone conformations of modeled and observed LRRs

^a The symbols α, α_L, γ, β, and β_p denote, respectively, residue backbone conformations closed to the right, left α-helical, and 3₁₀-helical conformations, the β-conformation and polyproline II helix conformations. Symbol ψ denotes unusual conformation with the dihedral angles φ = −140°; ξ = −160°.

^b The arrows, lines, and rectangle denote β-strands, turn regions, and linear conformation of the variable region, respectively.
