Geomicrobiology
Antifreeze proteins are specialized biomolecules produced by certain organisms that enable them to survive in extremely cold environments by lowering the freezing point of their bodily fluids. These proteins bind to ice crystals and inhibit their growth, preventing the formation of large ice structures that could damage cellular structures. Their presence is crucial for the survival of various microorganisms in polar regions and high-altitude habitats, allowing them to thrive where temperatures drop significantly.
