Polypentagonal ice-like water networks emerge solely in an activity-improved variant of ice-binding protein [Biophysics and Computational Biology]

Polypentagonal water networks were recently observed in a protein capable of binding to ice crystals, or ice-binding protein (IBP). To examine such water networks and clarify their role in ice-binding, we determined X-ray crystal structures of a 65-residue defective isoform of a Zoarcidae-derived IBP (wild type, WT) and its five...
