A comparison of calculated energies using Eq. 11 versus published or experimentally determined stabilities. GER15 = (GER)15GPCCG, ref (46); ABB energy from this study, Tm from A:2B mixture; POG = (POG)10 homotrimer; PPG = (PPG)10 homotrimer. The remaining species annotated as described in ref (23): R10:E10 = 1:1 mixture of (PRG)10 and (EOG)10, association stoichiometry not specified; E10:R10:POG = 1:1:1 mixture of (EOG)10, (PRG)10 and (POG)10; E5 = (EOGPOG)5 homotrimer, R5 = (PRGPOG)5 homotrimer; E3 = (POG)2(EOGPOG)3(POG)2 homotrimer, R3 = (POG)2(EOGPOG)3(POG)3 homotrimer. Formula for the bestfit line (R2 = 0.88) in Eq. 12.
