Figure 1. van Hove self-correlation function Gs(r, Δt) of ubiquitin in glycerol/water solutions.

Figure 1

The inset shows the non-Gaussian parameter, α2 of ubiquitin where all protein atoms are included in the analysis. The peak in α2 and a secondary ‘hopping peak’ in Gs(r, Δt) observed for glycerol are signatures of dynamic heterogeneity in the dynamics of GF liquids. The addition of water suppresses these features due to the uncooperative nature of TIP3P water model.
