Ice control by antifreeze proteins: From interfacial thermodynamics, and engulfment resistance, to thermal hysteresis activity using theory and computation
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-08-01

Molecular Dynamics Simulation Studies on Interfacial Dynamics of Proteins
Clusters of water molecules embedded in proteins or at the interface between globules mediate protein dynamics, allostery and charge transfer. Confined clusters of water molecules exhibit dynamics distinct from dynamics of water in the bulk or in the hydration layer around biomolecules. Here, we …

Structure-Function Studies of a Truncated Ice-Nucleation Protein
Bacterial ice-nucleation proteins (INPs) initiate water freezing at high subzero temperatures. Despite having an opposite function to antifreeze proteins (AFPs), INPs and AFPs both have significant similarities in sequence and structure. Based on these common features, I hypothesize that INPs also …

Tracing The Origin Of A Lectin-like Antifreeze Protein
Type II antifreeze proteins (AFPs) are C-type lectin homologs found in three lineages of teleost fish (Cottidae, Clupeiformes and Osmeriformes). Previous work demonstrated that the AFP gene was horizontally transferred from the Atlantic herring to the smelt, and also showed that the herring is not …

Hemmung der Eisrekristallisation in wässrigen Lösungen durch Antigefrierglykopeptide
Antifreeze proteins (AFP) inhibit the growth of ice crystals and, thus, play an important role in the survival of many organisms at temperatures below the freezing point. But many aspects of the mechanism of action are still not understood, especially for antifreeze glycoproteins and glycopeptides …

Effect of environmental temperature on Antarctic fish antifreeze protein activity and concentration
… attributable in part to the evolution of blood antifreeze proteins (AFPs) that adsorb to the surface of internalized ice crystals and inhibit their growth. The non-colligative depression of the blood serum freezing point can contribute enough protection to prevent freezing down to or below the …

A Molecular and Phylogenetic Analysis of Cryobiosis in Nematodes of the Genus Panagrolaimus
… adaptations may include the synthesis of proteins such as antifreeze proteins or cryoprotectants such as trehalose, the elimination of ice nucleators, and the expression of stress associated proteins (such as molecular chaperones, antioxidants, late embryogenesis abundant (LEA) proteins). …

Insights into the seasonal ecology and thermal biology of the lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae)
… burrowing, dispersal) and physiological (e.g., antifreeze proteins, cryoprotectants) strategies to survive harsh conditions. Commodity type and natural refugia further influence survival, and responses vary by insect species, sex, life stage, prior cold exposure, and population, highlighting the …

The influence of environmental temperature on the thermal tolerance of Antarctic notothenioid fishes
… and limited by their circulating levels of antifreeze proteins (AFPs). To investigate the differences in freeze avoidance between these regions’ endemic ichthyofaunas blood serum freezing points were measured in 11 of the 14 species of the Antarctic icefishes (family Channichthyidae). While …
