ABSTRACT Antifreeze glycoproteins from the Greenland cod Boreogadus saida were dimethylated at the N-terminus (m*AFGP) and their dynamics and conformational properties were studied in the presence of ice using ^sup 13^C-NMR and FTIR spectroscopy. ^sup 13^C-NMR experiments of m*AFGP in D^sub 2^O, in H^sub 2^O, and of freeze-dried m*AFGP were performed as a function of temperature. Dynamic parameters (^sup 1^H T^sub 1p^ and T^sub CH^) obtained by varying the contact time revealed notable differences in the motional properties of AFGP between the different states. AFGP/ice dynamics was dominated ...
