Characterization of an antifreeze glycopeptide gene from the Antarctic cod, Notothenia neglecta, and a functional study of the "pre-" sequence of this antifreeze glycopeptide
The antarctic fish, Notothenia neglecta, synthesizes a series of 8 different-sized antifreeze glycopeptides (AFGP 1 to 8) which lower the freezing point of its body fluids below that of sea water. I report here the sequence of one of its AFGP genes. The structural gene contains 46 tandemly repeated...
