Table 4 Mean ΔΔG (in kcal/mol) for μSBSs from \(\mathcal {M}_{\text {PoP}}\) obtained from SBSs at different codon positions (I, II, III). In the lower part of the table, the mean ΔΔG is computed by considering also the synonymous mutations (with ΔΔG=0) and the degeneracy (the number of SBSs leading to a μSBS)
