Figure 4From: Dependence of α-helical and β-sheet amino acid propensities on the overall protein fold typeRelationship between the amino acid propensities. Amino acid propensities, P, for Glu and Lys for each SCOP fold for α-helices (A) and β-strands (B). The SCOP classes are: all-α proteins (○), α/β proteins (□), α + β proteins (Δ) and all-β proteins (+).Back to article page
