Antifreeze Proteins Categories.
 |
Antifreeze Proteins, Type I - A subclass of ANTIFREEZE PROTEINS that are 3-5 kD in size and contain a single alanine-rich amphipathic alpha-helix. |
|
Antifreeze Proteins, Type II - A subclass of ANTIFREEZE PROTEINS that have a cystine-rich globular structure of approximately 14 kD. |
|
Antifreeze Proteins, Type III - A subclass of ANTIFREEZE PROTEINS that are globular, 6.5 kD in size and contain compact beta-sheet structures. |
|
Antifreeze Proteins, Type IV - A subclass of ANTIFREEZE PROTEINS that contain four amphipathic alpha-helices folded into an antiparallel helix bundle. |
