Interaction energy distribution. (A and B) The probability distribution function of Van der Waals energy of urea (A) and water (B) in the first solvation shell of mutant lysozyme and in the bulk region, respectively, with the rest of system. (C and D) The probability distribution function of electrostatic energy of urea (C) and water (D) in the first solvation shell of mutant lysozyme and in the bulk region, respectively, with the rest of system. The first solvation shell (FSS) is defined as within 5.0 Å of protein and the bulk region is defined as not within 6.0 Å of protein.
