Dependence of protein stability on the structure of the denatured state: free energy calculations of I56V mutation in human lysozyme.

Abstract excerpt

Free energy calculations were carried out to understand the effect of the I56V mutation of human lysozyme on its thermal stability. In the simulation of the denatured state, a short peptide including the mutation site in the middle is employed. To study the dependence of the stability on the denatured-state structure, five different initial conformations, native-like, extended, and three random-coil-like...
