Frequency plots of C-terminal β-strands from Proteobacteria. Frequency plots generated from unique peptides of α-proteobacteria are shown in Figure 5A, of β-Proteobacteria in Figure 5B, of γ-Proteobacteria in Figure 5C, of δ-Proteobacteria in Figure 5D and of ε-Proteobacteria in Figure 5E. The frequency plots are overall very similar; an exception is the high frequency of His at the +3 position in β-Proteobacteria and of Tyr at the +5 position in ε-Proteobacteria.
