CRUSTACEAN-DERIVED PROTEIN HAVING ANTIFREEZE ACTIVITY

摘要

A crustacean-derived protein having antifreeze activity which under reduced conditions has a molecular weight, as measured by sodium dodecyl sulfate (SDS) - polyacrylamide gel electrophoresis, of about 37,000, about 16,000, and/or about 15,400; and the N-terminal amino acids are indicated by SEQ ID No. 1 or SEQ ID No. 2. Since this protein is excellent in comparison to the conventional antifreeze proteins from the standpoints of safety, activity, production rate, cost, and the like, use is possible in a wide range of fields, beginning with foods.
