Protein
Ice-binding protein K3-B1
Organism
Typhula ishikariensis
Function
Binds to the surface of ice crystals. Has low thermal hysteresis (TH) activity, which is the ability to lower the freezing point of an aqueous solution below its melting point (PubMed:22645341). The TH activity of this protein is approximately 0.3 degrees Celsius at 11 mM (PubMed:27613857).
Similarity
Belongs to the ice-binding protein family.
