Evolution of Fish Antifreeze Gene Sheds Light on Climate History

WebFour distinct macromolecular antifreezes have been isolated and characterized from different marine fish. These include the glycoprotein antifreezes (Mr 2.5-33 K), which are made up of a repeating tripeptide (Ala-Ala-Thr)n with a disaccharide attached to the threonyl residues, and three antifreeze protein (AFP) types. 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.
