Antifreeze Protein Unexpectedly Holds Water (VIDEO)
Caption
The structure of the hyperactive Type I antifreeze (Maxi) showing the extensive array of buried water molecules. The protein is a homodimer of beta-hairpin subunits (colored yellow and orange). Waters are represented by red spheres and their hydrogen-bonding interactions by black dashed lines. This video relates to a paper that appeared in the Feb. 14, 2014, issue of Science, published by AAAS. The paper, by Tianjun Sun at Queen’s University in Kingston, Ontario, Canada, and colleagues was titled, "An Antifreeze Protein Folds with an Interior Network of More Than 400 Semi-Clathrate Waters."
