Comparison of selection estimates Δη between different protein secondary structures. values are scaled relative to the genome-wide most selectively-favored codon. Points represent values for each codon, while error bars represent the 95% posterior probability intervals. Codons showing significant selective shifts are colored by amino acid property. Negative values indicate a change in the selectively-favored codon relative to the genome-wide most selectively-favored codon. The Deming regression slope β and 95% confidence intervals (noted in parentheses) are represented by solid and dashed black lines, respectively. ρS indicates the Spearman rank correlation between the Δη of the two regions. (A,D) Coils vs. Helices. (B,E) Coils vs. Sheets. (C,F) Helices vs. Sheets
