Recrystallization Inhibition

Ice-binding proteins (IBPs) have ice recrystallization inhibition (IRI) activity. IRI property has been extensively utilized for the cryopreservation of different types of cells and tissues. Recent reports demonstrated that IRI can also play a significant role in protecting proteins from freezing damage during freeze–thaw cycles. In this study, we hypothesized that the protective capability of IBPs on proteins against freeze–thaw damage is proportional to their IRI activity. Hence we used two IBPs: one with higher IRI activity (LeIBP) and the other with lower activity (FfIBP). Yeast alcohol dehydrogenase (ADH) was used as a freeze-labile model protein. IBPs and ADH were mixed, frozen at −20 °C, and thawed repeatedly. The structure of ADH was assessed using fluorescence emission spectra probed by 1-anilinonaphthalene-8-sulfonate over the repeated freeze–thaw cycles. The activity was monitored at 340 nm spectrophotometrically. Fluorescence data and activity clearly indicated that ADH without IBP was freeze-labile. However, ADH maintained about 70% residual activity after five repeated cycles at a minimal concentration of 0.1 mg mL-1 of high IRI-active LeIBP, but only 50% activity at 4 mg mL−1 of low active FfIBP. These results showed that the protection of proteins from freeze–thaw stress by IBPs is proportional to their IRI activity.

The One

At subzero temperatures extracellular ice growth can kill plants by dehydrating cells and rupturing their membranes. Some grasses can protect themselves from this damage by producing antifreeze proteins (AFPs). These AFPs irreversibly adsorb to growing ice crystals and prevent further gowth. This is measured by ice-recrystallization inhibition (IRI), whereby ice crystals remain small at high sub-zero temperatures. An AFP from Brachypodium distachyon, a temperate grass, has been structurally modelled as a left-handed beta helix with two flat ‘faces’ on either side of the molecule. I am trying to determine which ‘face’ is important for ice adsorption. I have made mutations in the sequence encoding the AFP so that a small, flat amino acid is replaced by a bulky residue, which will likely interfere with the “fit” of the protein to ice. A mutation on one of the flat ‘faces’ of the protein seems to retain all AFP activity, whereas mutations on the opposite ‘face’ appear to cause a loss in activity. Therefore, I believe that this latter ‘face’ is the one important for ice-binding. By understanding how proteins interact with ice, it may be possible to develop new technologies such as environmentally-friendly de-icing agents.

Living Organisms

More than 80% of Earth’s surface is exposed periodically or continuously to temperatures below 5 °C. Organisms that can live in these areas are called psychrophilic or psychrotolerant. They have evolved many adaptations that allow them to survive low temperatures. One of the most interesting modifications is production of specific substances that prevent living organisms from freezing. Psychrophiles can synthesize special peptides and proteins that modulate the growth of ice crystals and are generally called ice binding proteins (IBPs). Among them, antifreeze proteins (AFPs) inhibit the formation of large ice grains inside the cells that may damage cellular organelles or cause cell death. AFPs, with their unique properties of thermal hysteresis (TH) and ice recrystallization inhibition (IRI), have become one of the promising tools in industrial applications like cryobiology, food storage, and others. Attention of the industry was also caught by another group of IBPs exhibiting a different activity—ice-nucleating proteins (INPs). This review summarizes the current state of art and possible utilizations of the large group of IBPs.
