| abstract |
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. n 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. |
