Structure predictions for salmine and squid protamine using different methods. Helical structure, turns and random coil are denoted by h, t and c, respectively. The last line shows the consensus prediction for salmine (A) and the Sp1 (B) and Sp2 (C) variants of squid protamine. (D) Proportions of secondary structure motifs for the consensus prediction for salmine, Sp1 and Sp2.
