Hydration and protein dynamics of HEWL-RC in crowding conditions plotted as a function of protein-protein distance. a, The protein-protein distance is defined as the average surface-to-surface distance between proteins using a spherical approximation, which can be estimated for each concentration. b, Assuming a homogeneous mixture, the average surface-to-surface distance between proteins can be estimated, revealing that the transition occurs at a protein-protein distance of 30-40 Å.
