AFP binds to small ice crystals thus inhibiting their growth.. There are 3 types of AFP which differ in the ice crusts face to which they bind. AFP I is Ala-rich and alpha helical AFP II is Cys-rich and globular AFP III is globular For winter flounder antifreeze protein type I see User:Mary Ball/AFP. For insect antifreeze protein see RiAFP For perennial ryegrass see IRI3 For arctic yeast see IBP LEUSY For yellow mealworm antifreeze protein see Tenebrio molitor Antifreeze Protein (TmAFP) and Thermal hysteresis protein YL-1. For Marinomonas primoryensis antifreeze protein see A1YIY3 9GAMM). Relevance AFPs are added to ice cream and yogurt. AFPs are tested as freeze tolerant for crops, cryosurgery, hypothermia therapy, food preservation and tissue transplant preservation. Structural highlights AFP flat surface presents Thr residues at distances which match those of the primary prism plane of ice thus allowing for favorable interactions between the protein and ice crystals. Fungal antifreeze protein (PDB code 3vn3) is shown. 3D Structures of antifreeze protein Antifreeze protein 3D structures
