  1. All values in kcal/mol, and ± shows bootstrap error estimate. \(RF^{exp}_R\) indicates value ranges calculated using \(RF_R = RF_{mutant}/RF_{wildtype}\) from previously reported experimental RF measurements, where "a" stands for measurements for FPV, the prodrug of APV. \(RF^{calc}_R\) indicates average calculated \(RF_R\) value from the distribution described in Eq. 4 with subscript and superscript corresponding to lower and upper bound of 95% credible interval, respectively
