WebNov 1, 2014 · Antifreeze proteins were first identified in the blood of fish, living in ice-laden seas ( DeVries and Wohlschlag, 1969, Scholander et al., 1953, Scholander et al., 1957 ). Later proteins with similar function were also found in certain insects, plants and microorganisms ( Griffith and Ewart, 1995 ). WebFish antifreeze proteins (APs) including both glycoproteins and small proteins are associated with freezing avoidance in most polar fishes. There are two major types of …
WebThe mechanism by which fish antifreeze proteins cause thermal hysteresis Antifreeze proteins are characterised by their ability to prevent ice from growing upon cooling below the bulk melting point. This displacement of the freezing temperature of ice is limited and at a sufficiently low temperature a rapid ice growth takes place.
WebMost marine fish from temperate and tropical regions don’t have antifreeze proteins, and would freeze to death in the frigid Antarctic waters.
