INPN

WHY INP

Ice-nucleation protein (INP), an outer membrane protein from Pseudomonas syringae, is responsible for promoting nucleation of ice at relatively high temperatures (above -50C). The proteins are localised at the outer membrane surface and can cause frost damage to many plants. It is composed of three domains structurally distinguished as the N-terminal domain (191 amino acids, 15% of the protein), which is the portion most responsible for targeting to the cell surface, the C-terminal domain (49 amino acids, 4% of the protein), and the central domain, composed of repeats comprising an 8-, 16-, and 48-residue periodicity that acts as a template for ice crystal formation.
