Abstract
Nowadays, it is urgent to produce in larger quantities and more sustainably to reduce the gap between food supply and demand. In a circular bioeconomy vision, insects receive great attention as a sustainable alternative to satisfy food and nutritional needs. Among all insects, Tenebrio molitor (TM) is the first insect approved by the European Food Safety Authority as a novel food in specific conditions and uses, testifying its growing relevance and potential. This review holistically presents the possible role of TM in the sustainable and circular solution to the growing needs for food and nutrients. We analyze all high value-added products obtained from TM (powders and extracts, oils and fatty acids, proteins and peptides, and chitin and chitosan), their recovery processes (evaluating the best ones in technical and environmental terms), their nutritional and economical values, and their biological effects. Safety aspects are also mentioned. TM potential is undoubted, but some aspects still need to be discussed, including the health effects of substances and microorganisms in its body, the optimal production conditions (that affect product quality and safety), and TM capacity to convert by-products into new products. Environmental, economic, social, and market feasibility studies are also required to analyze the new value chains. Finally, to unlock the enormous potential of edible insects as a source of nutritious and sustainable food, it will be necessary to overcome the cultural, psychological, and regulatory barriers still present in Western countries.

Abstract
The antifreeze activity of a type-III antifreeze protein (AFP) expressed in ocean pout (Zoarces americanus) is compared with that of a specific mutant (T18N) using all-atom molecular dynamics simulations. The antifreeze activity of the mutant is only 10% of the wild-type AFP. The results from this simulation study revealed the following insights into the mechanism of antifreeze action by type-III AFPs. The AFP gets adsorbed to the advancing ice front due to its hydrophobic nature. A part of the hydrophobicity is caused by the presence of clathrate structure of water molecules near the ice-binding surface (IBS). The mutation in the AFP disrupts this structure and thereby reduces the ability of the mutant to adsorb to the ice-water interface leading to the loss of antifreeze activity. The mutation, however, has no effect on the ability of the adsorbed protein to bind to the growing ice phase. Simulations also revealed that all surfaces of the protein can bind to the ice phase, although the IBS is the preferred surface.

Abstract
Antifreeze proteins (AFPs) provide protection for organisms subjected to the presence of ice crystals. The psychrophilic diatom Fragilariopsis cylindrus which is frequently found in polar sea ice carries a multitude of AFP isoforms. In this study we report the heterologous expression of two antifreeze protein isoforms from F. cylindrus in Escherichia coli. Refolding from inclusion bodies produced proteins functionally active with respect to crystal deformation, recrystallization inhibition and thermal hysteresis. We observed a reduction of activity in the presence of the pelB leader peptide in comparison with the GS-linked SUMO-tag. Activity was positively correlated to protein concentration and buffer salinity. Thermal hysteresis and crystal deformation habit suggest the affiliation of the proteins to the hyperactive group of AFPs. One isoform, carrying a signal peptide for secretion, produced a thermal hysteresis up to 1.53°C±0.53°C and ice crystals of hexagonal bipyramidal shape. The second isoform, which has a long preceding N-terminal sequence of unknown function, produced thermal hysteresis of up to 2.34°C±0.25°C. Ice crystals grew in form of a hexagonal column in presence of this protein. The different sequences preceding the ice binding domain point to distinct localizations of the proteins inside or outside the cell. We thus propose that AFPs have different functions in vivo, also reflected in their specific TH capability.

Abstract
We have previously identified a Thr- and Cys-rich thermal hysteresis (antifreeze) protein (THP) in the beetle Tenebrio molitor that has 10-100 times the freezing point depression activity of fish antifreeze proteins. Because this 8.4 kDa protein is significantly different in its properties from THP preparations previously reported from this insect, a thorough search was undertaken for other antifreeze types. Many active proteins were observed, but all appeared to be isoforms of the THP that differed in their number of 12-amino acid repeats (consensus sequence CTxSxxCxxAxT), amino acid substitutions, and N-linked glycosylation. Mass spectral analysis has matched most of these isoforms with cDNA sequences of 17 different clones from a larval fat body library that encode eight different mature THPs containing 84, 96, or 120 amino acids. Genomic Southern blots suggest there may be 30-50 tightly linked copies of the gene, which is a signature consistently seen with unrelated fish antifreeze protein genes, and one that has been associated with the need to rapidly increase gene product in response to climate change. A three-dimensional model is proposed for the fully disulfide-bonded structure of T. molitor THP, which can accommodate addition or deletion of 12-amino acid repeats. The structure is a beta-helix that places most of the Thr in a regular array on one side of the protein to form a putative ice-binding surface.

Abstract
Thermal hysteresis proteins (THPs), which depress the freezing point of water below the melting point (producing a characteristic thermal hysteresis), are well known for their antifreeze activity in both fish and terrestrial arthropods, but have only recently been identified in plants. This study describes the purification of a THP from winter-collected bittersweet nightshade, Solanum dulcamara, using ion exchange and preparative 'free flow' isoelectric focusing. The THP has a molecular mass of 67 kDa (considerably larger than those of animal THPs), and an unusually high glycine component (23.7 mol%). Treatments of the THP with periodate or borate caused inactivation, suggesting the presence of carbohydrate. More specific treatments directed at galactose (beta-galactosidase or Abrus precatorius lectin) also resulted in inactivation, indicating that galactose is present. A thermal hysteresis activity versus THP concentration curve showed that the specific activity of the S. dulcamara THP is lower than that of any known animal THP. The functional significance of this low activity is discussed.

Abstract
Underivatized 1,25-dihydroxy[26,27-3H]vitamin D-3 was successfully used to photoaffinity label the 1,25-dihydroxyvitamin D-3 receptor. The covalent incorporation of tritium into the receptor protein was induced by ultraviolet irradiation of the receptor-1,25-dihydroxy[26,27-3H]vitamin D-3 complex in crude pig intestinal nuclear extract. The amount of incorporated label increased with increasing time of irradiation and was dependent on light of wavelengths 220-280 nm. Sodium dodecyl sulfate polyacrylamide gel electrophoresis and fluorography were used to demonstrate that label was incorporated primarily into the 1,25-dihydroxyvitamin D-3 receptor. In addition, the label incorporation was eliminated by competition with a 100-fold excess nonradioactive 1,25-dihydroxyvitamin D-3, indicating that the label was specific for the steroid binding site. Since 1,25-(OH)2[26,27-3H]vitamin D-3 is readily available and requires no special precautions for its preparation and handling, it should be a useful photoaffinity label for future studies of the receptor.

Abstract
Antifreeze proteins, produced by many cold water marine teleost fish and terrestrial arthropods (insects, spiders, etc.), inhibit ice crystal growth by a non-colligative mechanism, probably by adsorbing onto the surface of potential seed ice crystals and thereby blocking growth at preferred growth sites. In this study it is demonstrated that the activity of two insect antifreeze proteins is greatly increased by the addition of specific rabbit polyclonal antibodies to the antifreezes. A model is presented which suggests that the enhancement occurs because the antifreeze-antibody complex, being much larger than the antifreeze protein alone (a minimal 7-8-fold increase in size), blocks a larger area of the ice crystal surface and extends further above the surface, thus requiring the temperature to be further lowered before crystal growth proceeds. This idea is further supported by the finding that addition of goat anti-rabbit IgG to the antifreeze protein + anti-antifreeze protein antibody complexes further enhanced activity.

Abstract
Antifreeze proteins (AFP) are able to inhibit the growth of ice-crystals at temperatures below the equilibrium freezing point (Tf) of hemolymph. The analysis of AFP activity has commonly involved the use of direct microscopic observation of a sample following inoculation with ice. The resulting activity, defined as the amount of thermal hysteresis observed between Tf and the subsequent rapid growth of ice, has been reported to range up to 7 degrees C. However, most studies report high level of variation, possibly due to ice-crystal size variability and the presence of non-visible ice nuclei. We describe a new method of analysis of AFP activity using differential scanning calorimetry (DSC). DSC analysis reveals much higher activity, up to 10 degrees C, with less variation observed within a sample, and is not subject to the difficulty of accurate assessment of ice-crystal volume.

Abstract
The effectiveness of water binding of antifreeze glycoproteins relative to hemoglobin, cytochrome c and polyvinylpyrrolidone was determined by analyzing results obtained in an isopiestic study at 25 degrees C. The net weight of water which moved from a protein/NaCl aqueous sample to a saturated NaCl reference solution increased in the order: antifreeze glycoprotein, hemoglobin, polyvinylpyrrolidone and cytochrome c. Since the glycoproteins were least effective in transporting water we conclude that, of the proteins studied, the glycoprotein was most effective in binding water under equilibrium conditions at 25 degrees C.
