Figure 3
Amino-acid compositions of different classes of β-bulge in the Proteins4K database. The four positions 0, 1, 2, X are as shown in Fig. 1[link]. The numbers in the figure are the percentages of the total for all 20 contributed by each individual amino-acid residue. (a) The three classes of β-bulge: classic (5133), G1α (3348) and G1β (1506). (b) Division of G1α β-bulges into those present in β-bulge loop-5 (BBL-5; 2154) and loop-6 (BBL-6; 1155) and of G1β β-­bulges into those present in (1283) or absent from (223) β-links.
