Secondary/tertiary structure (Left) and surface structure with the IBS shown in light blue (Right). (A) Protein ID code 1WFA. Type I $\alpha$-helical fish protein. Predicted IBS matches that identified by ref. 3. (B) Protein ID code 1HG7. Type III globular fish protein. Predicted IBS matches that identified by ref. 16. (C) Protein ID code 3P4G. Ca²⁺-dependent bacterial protein. Predicted IBS matches that identified by ref. 39. (D) Protein ID code 1M8N. Hyperactive AFP from the spruce budworm beetle. Predicted IBS matches that determined by ref. 40. Visualization done with PyMOL (41).
