Analysis of Water and Hydrogen Bond Dynamics at the Surface of an Antifreeze Protein

Figure 2

Power spectra of the velocity autocorrelation function of water in hydration layers around Plane 1 (red), Plane 2 (green), and Plane 3 (blue) of the protein, as well as for bulk water (black), at 300 K. (a) Power spectrum of water in the hydration layer, taken to be 5 Å from the surface of the wild-type AFP. (b) Power spectrum of water hydrogen bonding to wild type AFP. (c) Same as (b), but for mutant AFP.
