Biological ice nucleation plays a key role in the survival and adaptation of cold-adapted organisms. Several species of bacteria, fungi, and insects produce ice nucleators (INs) that enable ice formation of ice at temperatures above -10 oC. Bacteria

Antifreeze glycoproteins (AFGPs) are able to bind to ice, halt its growth, and are the most potent inhibitors of ice recrystallization known. The structural basis for AFGP’s unique properties remains largely elusive. Here we determined the antifree

We study the effect of antifreeze glycoproteins (AFGPs) on the survival of organoids under hypothermic conditions. We find that the survival of organoids in cold conditions depends on their developmental stage. Mature organoids die within 24 h when b

Cold-adapted organisms use antifreeze proteins (AFPs) or ice-nucleating proteins (INPs) for the survival in freezing habitats. AFPs have been reported to be able to inhibit the activity of INPs, a property that would be of great physiological relevan

In some cold-adapted organisms, over a dozen isoforms of antifreeze (glyco)proteins or AF(G)Ps are present. Although these isoforms are structurally similar, their ability to inhibit ice growth varies significantly, and, in some fish, passive isoform

Antifreeze proteins (AFPs) and antifreeze glycoproteins (AFGPs) inhibit ice growth via an adsorption-inhibition mechanism that assumes irreversible binding of AF(G)Ps to embryonic ice crystals and the inhibition of further growth. The irreversible bi

Fish antifreeze proteins (APs) including both glycoproteins and small proteins are associated with freezing avoidance in most polar fishes. There are two major types of APs, the antifreeze glycoproteins (AFGPs) found in Antarctic notothenioid fishes

We combine Terahertz absorption spectroscopy (THz) and molecular dynamics (MD) simulations to investigate the underlying molecular mechanism for the antifreeze activity of one class of antifreeze protein, antifreeze protein type III (AFP-III) with a

We study the solution structure of antifreeze glycoproteins (AFGPs) with linear and two-dimensional infrared spectroscopy (2D-IR). With 2D-IR, we study the coupling between the amide I and amide II vibrations of AFGPs. The measured nonlinear spectral
