Antifreeze Proteins
A collection of antifreeze proteins. Antifreeze proteins are found in a variety of species that tolerate cold temperatures. These include arctic fish, antarctic bacteria, plants, insects, and mold.
All of these proteins bind to water and lower the freezing point. Can you figure out what these proteins have in common besides their function?
