2. Using molecular simulations it is possible to compute the free energy change AG for the nonphysical reaction CH3-CH2-CH3 CH3-CH3 (Propane Ethane) in any desired solvent. Simulation data give the following results AG°(vacuum)=0.5 kcal/mol AG (octanol)=2.0 kcal/mol AG (water) 1.0 kcal/mol (a) The experimentally measured free energy of transfer AGx(propane) of propane from octanol to water is 4 kcal/mol and from vacuum (gas phase) to water is -0.2 kcal/mol. Calculate the corresponding values of AGOx(ethane) from octanol to water and from vacuum to water. b) Assume that the free energy of transfer of a methylene group from water to octanol is a measure of the strength of the hydrophobic driving force for burial of such a group during protein folding. Calculate the expected approximate decrease in stability (as a result of reduced hydrophobicity) for a Leu Ala substitution at a buried site in a monomeric globular protein. The measured decrease in stability is twice the theoretical…
