From: Novel dimeric β-helical model of an ice nucleation protein with bridged active sites
Size comparison of Pb INP to other known AFPs. Eight dimers of the Pb INP model were aligned end to end to approximate the size of the repetitive central domain of the protein (ca. 320 Å in length). The N and C termini are indicated. The crystal structures of all known AFPs are aligned with their IBSs facing Pb INP. Each protein is rainbow coloured with blue representing the N terminus and red representing the C terminus. All structures are to scale. Type I AFP (PDB 1WFA), type II AFP (PDB 2ZIB), type III AFP (PDB 1HG7), Mp AFP_RIV -Marinomonas primoryensis region IV AFP (PDB 3P4G), sbwAFP - spruce budworm AFP (PDB 1M8N), sfAFP - snow flea AFP (PDB 2PNE), Tm AFP - Tenebrio molitor AFP (PDB 1EZG).
