Figure 8: Schematic diagram of the dimerization of PbINP using tyrosine ladders. Dimerization allows for tetrapeptides of each side of a monomer to create a relatively flat Thr-X-Thr based ice binding surface. Threonine residues used on the ice binding surface are highlighted in red. S: Ser, L: Leu, T: Thr, A: Ala, and Q: Gln. Adapted from Garnham et al. [13].
