Figure 8From: Dependence of α-helical and β-sheet amino acid propensities on the overall protein fold typeRelationship between the frequencies of exposed residues. Relationship between the frequencies of exposed Ile, Leu, Glu, Lys and Arg residues, f ILEKR , and exposed Ser, Thr and Asn residues, f STN , in β-strands. The SCOP classes are: α/β proteins (□), α + β proteins (Δ) and all-β proteins (+).Back to article page
