Journal ArticleDOI
Antifreeze and ice nucleator proteins in terrestrial arthropods.
TL;DR: Many freeze-avoiding species do have proteins with ice-nucleating activity, and these proteins must be masked in winter, but in the beetles D. canadensis and Tenebrio molitor, AFPs in the hemolymph and gut inhibit ice nucleators.
Journal ArticleDOI
Thermal Hysteresis Protein Activity in Bacteria, Fungi, and Phylogenetically Diverse Plants
John G. Duman,T. Mark Olsen +1 more
TL;DR: This study shows for the first time that thermal hysteresis protein activity is also present in nonangiosperm plants, fungi, and bacteria, and identified for theFirst time in two additional kingdoms, the fungi and bacteria.
Journal ArticleDOI
Long-range protein-water dynamics in hyperactive insect antifreeze proteins.
Konrad Meister,Simon Ebbinghaus,Yao Xu,John G. Duman,Arthur L. DeVries,Martin Gruebele,David M. Leitner,Martina Havenith +7 more
TL;DR: Terahertz spectroscopy and molecular simulations are combined to prove that long-range protein–water interactions make essential contributions to the high antifreeze activity of insect AFPs from the beetle Dendroides canadensis.
Journal ArticleDOI
Inhibition of recrystallization of ice by insect thermal hysteresis proteins: A possible cryoprotective role
Charles A. Knight,John G. Duman +1 more
TL;DR: The studies outlined here demonstrate that the thermal hysteresis proteins from the overwintering larvae of the beetle Dendroides canadensis are extremely efficient in inhibiting ice recrystallization.
Journal ArticleDOI
Plant thermal hysteresis proteins
TL;DR: Winter stem fluid from the bittersweet nightshade, Solanum dulcamara L., showed the recrystallization inhibition activity characteristic of the animal thermal hysteresis proteins (THPs), suggesting a possible function for the THPs in this freeze tolerant species.
