Isolation and characterization of type I antifreeze proteins from Atlantic snailfish (Liparis atlanticus) and dusky snailfish (Liparis gibbus). (1/16)

Antifreeze proteins (AFPs) were isolated from the blood plasma of Atlantic snailfish Liparis atlanticus and dusky snailfish Liparis gibbus, which belong to the Teleost family Cyclopteridae, a close relative of sculpins. Using a combination of gel filtration chromatography and reversed-phase HPLC, proteins were purified to individual peaks. Atlantic snailfish plasma contained two different proteins (MW=9344, 9415) while dusky snailfish plasma contained five protein isoforms (MW=9514-9814), as determined by mass spectrometry. Further characterization revealed that these proteins are rich in alanine (>50 mol%), and have alpha-helical secondary structure that can undergo reversible thermal denaturation. Thermal hysteresis activities of these proteins were similar to each other but lower than the major type I AFPs from winter flounder. Results of this study have indicated that although the AFPs from snailfish are significantly larger than previously described type I AFPs, they share enough characteristics to be classified in this group.  (+info)

Structure of type I antifreeze protein and mutants in supercooled water. (2/16)

Many organisms are able to survive subzero temperatures at which bodily fluids would normally be expected to freeze. These organisms have adapted to these lower temperatures by synthesizing antifreeze proteins (AFPs), capable of binding to ice, which make further growth of ice energetically unfavorable. To date, the structures of five AFPs have been determined, and they show considerable sequence and structural diversity. The type I AFP reveals a single 37-residue alpha-helical structure. We have studied the behavior of wild-type type I AFP and two "inactive" mutants (Ala17Leu and Thr13Ser/Thr24Ser) in normal and supercooled solutions of H(2)O and deuterium oxide (D(2)O) to see if the structure at temperatures below the equilibrium freezing point is different from the structure observed at above freezing temperatures. Analysis of 1D (1)H- and (13)C-NMR spectra illustrate that all three proteins remain folded as the temperature is lowered and even seem to become more alpha-helical as evidenced by (13)C(alpha)-NMR chemical shift changes. Furthermore, (13)C-T(2) NMR relaxation measurements demonstrate that the rotational correlation times of all three proteins behave in a predictable manner under all temperatures and conditions studied. These data have important implications for the structure of the AFP bound to ice as well as the mechanisms for ice-binding and protein oligomerization.  (+info)

A mechanism for stabilization of membranes at low temperatures by an antifreeze protein. (3/16)

Polar fish, cold hardy plants, and overwintering insects produce antifreeze proteins (AFPs), which lower the freezing point of solutions noncolligatively and inhibit ice crystal growth. Fish AFPs have been shown to stabilize membranes and cells in vitro during hypothermic storage, probably by interacting with the plasma membrane, but the mechanism of this stabilization has not been clear. We show here that during chilling to nonfreezing temperatures the alpha-helical AFP type I from polar fish inhibits leakage across model membranes containing an unsaturated chloroplast galactolipid. The mechanism involves binding of the AFP to the bilayer, which increases the phase transition temperature of the membranes and alters the molecular packing of the acyl chains. We suggest that this change in acyl chain packing results in the reduced membrane permeability. The data suggest a hydrophobic interaction between the peptide and the bilayer. Further, we suggest that the expression of AFP type I in transgenic plants may be significant for thermal adaptation of chilling-sensitive plants.  (+info)

Solution structure of a hydrophobic analogue of the winter flounder antifreeze protein. (4/16)

The solution structure of a synthetic mutant type I antifreeze protein (AFP I) was determined in aqueous solution at pH 7.0 using nuclear magnetic resonance (NMR) spectroscopy. The mutations comprised the replacement of the four Thr residues by Val and the introduction of two additional Lys-Glu salt bridges. The antifreeze activity of this mutant peptide, VVVV2KE, has been previously shown to be similar to that of the wild type protein, HPLC6 (defined here as TTTT). The solution structure reveals an alphahelix bent in the same direction as the more bent conformer of the published crystal structure of TTTT, while the side chain chi1 rotamers of VVVV2KE are similar to those of the straighter conformer in the crystal of TTTT. The Val side chains of VVVV2KE assume the same orientations as the Thr side chains of TTTT, confirming the conservative nature of this mutation. The combined data suggest that AFP I undergoes an equilibrium between straight and bent helices in solution, combined with independent equilibria between different side chain rotamers for some of the amino acid residues. The present study presents the first complete sequence-specific resonance assignments and the first complete solution structure determination by NMR of any AFP I protein.  (+info)

Freezing of a fish antifreeze protein results in amyloid fibril formation. (5/16)

Amyloid is associated with a number of diseases including Alzheimer's, Huntington's, Parkinson's, and the spongiform encephalopathies. Amyloid fibrils have been formed in vitro from both disease and nondisease related proteins, but the latter requires extremes of pH, heat, or the presence of a chaotropic agent. We show, using fluorescence spectroscopy, electron microscopy, and solid-state NMR spectroscopy, that the alpha-helical type I antifreeze protein from the winter flounder forms amyloid fibrils at pH 4 and 7 upon freezing and thawing. Our results demonstrate that the freezing of some proteins may accelerate the formation of amyloid fibrils.  (+info)

The effect of hydrophobic analogues of the type I winter flounder antifreeze protein on lipid bilayers. (6/16)

The effect of four synthetic analogues of the 37-residue winter flounder type I antifreeze protein (AFP), which contain four Val, Ala or Ile residues in place of Thr residues at positions 2, 13, 24 and 37 and two additional salt bridges, on the binary lipid system prepared from a 1:1 mixture of the highly unsaturated DGDG and saturated DMPC has been determined using FTIR spectroscopy. In contrast to the natural protein, which increases the thermotropic phase transition, the Thr, Val and Ala analogues decreased the thermotropic phase transitions of the liposomes by 2.2 degrees Celsius, 3.4 degrees Celsius and 2.4 degrees Celsius, while the Ile analogue had no effect on the transition. Experiments performed using perdeuterated DMPC showed that the Ala and Thr peptides interacted preferentially with the DGDG in the lipid mixture, while the Val peptide showed no preference for either lipid. The results are consistent with interactions involving the hydrophobic face of type I AFPs and model bilayers, i.e. the same face of the protein that is responsible for antifreeze properties. The different effects correlate with the helicity of the peptides and suggest that the solution conformation of the peptides has a significant role in determining the effects of the peptides on thermotropic membrane phase transitions.  (+info)

Hyperactive antifreeze protein from winter flounder is a very long rod-like dimer of alpha-helices. (7/16)

The winter flounder (Pseudopleuronectes americanus) produces short, monomeric alpha-helical antifreeze proteins (type I AFP), which adsorb to and inhibit the growth of ice crystals. These proteins alone are not sufficiently active to protect this fish against freezing at -1.9 degrees C, the freezing point of seawater. We have recently isolated a hyperactive antifreeze protein from the plasma of the flounder with activity 10-100-fold higher than type I AFP. It is comparable in activity to the AFPs produced by insects, and is capable of conferring freeze resistance to the flounder. This novel AFP has a molecular mass of 16,683 Da and a remarkable amino acid composition that is >60% alanine. CD spectra indicate that the protein is almost entirely alpha-helical at 4 degrees C but partially denatures at 20 degrees C, resulting in a species with a moderately reduced helix content that is stable at up to 50 degrees C. This transformation correlates with irreversible loss of activity. Analytical ultracentrifugation (sedimentation velocity and equilibrium) indicates that the predominant species in solution is dimeric (molecular weight, 32,275). Size-exclusion chromatography reveals a 2-fold higher apparent molecular weight suggesting that this molecule has an unusually large Stokes radius. The axial ratio of the dimer calculated from the sedimentation velocity data is 18:1, confirming that this protein has an extraordinarily long, rod-like structure, consistent with a novel dimeric alpha-helical arrangement. The structural model that best fits these data is one in which the approximately 195 amino acids of each monomer form one approximately 290-A long alpha-helix and associate via a unique dimerization motif that is distinct from that of the leucine zipper and any other coiled-coil.  (+info)

Type I antifreeze proteins expressed in snailfish skin are identical to their plasma counterparts. (8/16)

Type I antifreeze proteins (AFPs) are usually small, Ala-rich alpha-helical polypeptides found in right-eyed flounders and certain species of sculpin. These proteins are divided into two distinct subclasses, liver type and skin type, which are encoded by separate gene families. Blood plasma from Atlantic (Liparis atlanticus) and dusky (Liparis gibbus) snailfish contain type I AFPs that are significantly larger than all previously described type I AFPs. In this study, full-length cDNA clones that encode snailfish type I AFPs expressed in skin tissues were generated using a combination of library screening and PCR-based methods. The skin clones, which lack both signal and pro-sequences, produce proteins that are identical to circulating plasma AFPs. Although all fish examined consistently express antifreeze mRNA in skin tissue, there is extreme individual variation in liver expression - an unusual phenomenon that has never been reported previously. Furthermore, genomic Southern blot analysis revealed that snailfish AFPs are products of multigene families that consist of up to 10 gene copies per genome. The 113-residue snailfish AFPs do not contain any obvious amino acid repeats or continuous hydrophobic face which typify the structure of most other type I AFPs. These structural differences might have implications for their ice-crystal binding properties. These results are the first to demonstrate a dual liver/skin role of identical type I AFP expression which may represent an evolutionary intermediate prior to divergence into distinct gene families.  (+info)

Antifreeze protein from an Antarctic fish [ PDB file ] [ PubMed link ] Many animals that live in extremely cold climates produce proteins that act to prevent the formation of ice crystals in the bodily fluids of the organism. Antarctic fish produce a range of such proteins, as the water temperatures can drop below 0 degrees Celsius. We have determined the structure of the type I antifreeze protein (SS3) from the blood of the shorthorn sculpin at both 5 degrees and -5 degrees. The structure largely comprises a long alpha-helix that displays conserved Thr residues (red) along a single surface. These residues are important for preventing the growth of ice crystals, although the mechanism of action is not currently understood. An additional short helix exists at the N-terminus of the protein, although the conformational relationship between the two helices is not well defined. This is the first solution structure of a wild-type type I antifreeze protein ...

This report describes the use of several isosteric non-natural nucleotides as probes to evaluate the roles of nucleobase shape, size, solvation energies, and π-electron interactions as forces influencing key kinetic steps of the DNA polymerization cycle. Results are provided using representative high- and low-fidelity DNA polymerases. Results generated with the E. coli Klenow fragment reveal that this high-fidelity polymerase utilizes hydrophobic nucleotide analogues with higher catalytic efficiencies compared to hydrophilic analogues. These data support a major role for nucleobase desolvation during nucleotide selection and insertion. In contrast, the low-fidelity HIV-1 reverse transcriptase discriminates against hydrophobic analogues and only tolerates non-natural nucleotides that are capable of hydrogen-bonding or π-stacking interactions. Surprisingly, hydrophobic analogues that function as efficient substrates for the E. coli Klenow fragment behave as noncompetitive or uncompetitive ...

Brrrrr! Its cold outside. Lots of animals are much better adapted to the cold weather than we are. Polar bears have thick fur, seals and whales have a layer of blubber and some birds migrate.. But what if youre a fish?. Birds and mammals are warm-blooded. They can keep their body temperature higher than the icy environment around them. Fish are cold-blooded. Their body temperature is the same as their surroundings. In the Arctic and Antarctic Oceans, the temperature is very chilly - below 0 degrees Celsius. The salt in the oceans stops them freezing.. Why dont fish freeze?. To stop their blood freezing, some fish that live in the Arctic and Antarctic have special antifreeze proteins.. Antifreeze proteins are very clever. They slow down the formation of bonds between water molecules, which prevents the formation of ice crystals in the fishs blood.. Scientists are working out how they could use these antifreeze proteins as a non-polluting de-icer for cars and machinery. Antifreeze proteins ...
Sea water freezes at -1.9C which presents a problem for any creature that wants to live in Arctic or Antarctic seas.

Antifreeze proteins (AFPs) enhance the survival of organisms inhabiting cold environments by affecting the formation and/or structure of ice. We report the crystal structure of the first multi-domain AFP that has been characterized. The two ice binding domains are structurally similar. Each consists of an irregular β-helix with a triangular cross-section and a long α-helix that runs parallel on one side of the β-helix. Both domains are stabilized by hydrophobic interactions. A flat plane on the same face of each domains β-helix was identified as the ice binding site. Mutating any of the smaller residues on the ice binding site to bulkier ones decreased the antifreeze activity. The bulky side chain of Leu174 in domain A sterically hinders the binding of water molecules to the protein backbone, partially explaining why antifreeze activity by domain A is inferior to that of domain B. Our data provide a molecular basis for understanding differences in antifreeze activity between the two domains of this
In contrast with the gas-phase reactions of atmospheric trace gases, there is incomplete or even controversial experimental information on the adsorption and surface state of molecules on ice surfaces due to the difficulties in experimental measurements. The heterogeneous reactions of atmospheric SO2, O3 and H2O2 are of special interest due to their impact on atmospheric pollution and climate. Here, quantum chemical modeling can provide valuable information which is not accessible from the direct measurements and can complement the perceptions obtained by experimental techniques. In the current work, we present the recent results of quantum chemical studies of the structure of adsorption complexes of SO2 molecule on the ice surface and various mechanisms of the further surface reactions of this molecule resulting in the formation of sulfurous acid and ionic dissociation. The comprehensive models of the ice surface, simple and composite models for the quantum chemical treatment of crystalline ...
Antifreeze proteins (AFPs) are often called ice-binding proteins and are thought to bind to ice or ice-like crystals exclusively to control their growth. Here molecular recognition repertoire of AFPs has been greatly expanded to other hydroxyl containing, non-ice like compounds. The inhibitory and habit-modifying effects of AFPs on the stable nuclei formation and on the crystals of nucleosides have been first demonstrated.

Antifreeze After watching murder, upon murder shows, one key thing Ive learned about antifreeze is that it has a sweet taste. While Ive never tasted it, I can say that TV has come in quite handy with the knowledge of avoiding antifreeze. The fatal substance is common in driveways in the winter. Some car owners take care of their car very carefully, which can involve antifreeze/coolant changes to prepare for harsh winter weather. A spill is common, and usually unintentional, but the small accident can be a fatal one. The sweet, intoxicating, smell and taste can be a lure for pups. The main ingredient in antifreeze is ethylene glycol. If ingested, the toxic chemical could lead to severe illnesses and even death. According to Petxtreme, "The mortality rate in dogs poisoned by antifreeze ranges from 50 to 70% and is thought to be even higher in cats." That is an extremely high number! If the animal isnt treated immediately, nervous system damage or kidney damage could occur, if death doesnt come ...
An apparatus for carrying out an enzymatic cycling reaction including a turntable arranged in a reaction tank, a number of reaction vessels being arranged in the turntable along its periphery, a device for circulating an antifreeze liquid through the reaction tank, a heater for heating the antifreeze liquid, a refrigerator for cooling the antifreeze liquid and a switching valve for selectively passing the antifreeze liquid through the heater or refrigerator. Until all the samples and cycling mixture are delivered into the reaction vessels, the reaction tank is held at a very low temperature at which no enzymatic cycling reaction proceeds. Then the antifreeze liquid is heated to an enzymatic cycling reaction temperature so as to perform the enzymatic cycling reaction simultaneously for liquids contained in all the reaction vessels for a desired period. Then, the antifreeze liquid is heated to a high temperature so as to stop simultaneously the cycling reaction in all the reaction vessels.

A diver himself, Cziko worked with other divers to place and maintain a temperature-logging device in McMurdo Sound, Antarctica, one of the coldest marine environments on the planet. The device recorded ocean temperatures there for 11 years, a substantial portion of notothenioids lifespan. Not once in that time did temperatures increase enough to overcome the antifreeze proteins anti-melting effect to completely rid the fishes of their internal ice, the researchers report.. The researchers suspect that the accumulation of ice inside the fishes could have adverse physiological consequences, but none have yet been discovered.. If the fishes are destined to carry ice crystals around all their lives, Cheng said, it is conceivable that ice particles could obstruct small capillaries or trigger undesired inflammatory responses. Cziko likens the potential threat to dangers posed by asbestos in the lungs or blood clots in the brain.. "Since much of the ice accumulates in the fishes spleens, we think ...

Having an atomistic insight into rare transitions and their respective important interactions is pivotal for understanding and experimentally controlling such processes. Water is an important agent on its own in facilitating protein folding, recognizing ice crystal planes (anti-freeze proteins) and in mediating protein association. By using molecular simulations we better understand the role of water at the hydration shell of single proteins in terms of structure and dynamics, we resolve the mechanisms of association and first steps of self-assembly food and anti-freeze proteins, and elucidate the role of water during protein association. Finally, in order to improve the efficiency of rare event sampling we develop a new algorithm which efficiently samples complex rare transitions as well as gives insight into the barrier region of the transition ...

Rat and mouse poisons are toxic to children. Antifreeze. Though there are several types of anticoagulants available as rat poison, some populations. The liver metabolizes ethylene glycol into glycolate and oxalate, which cause extensive cellular damage in various tissues, especially the kidneys, but across many different organs. A greedy rat can eat enough poison to kill 20 rats before he starts to feel sick and if a dog or cat eats the rat, the poison is transferred. Most rodent poisons use anti-coagulants that kill the animals by causing uncontrollable bleeding. But usually not quickly. It may sample a small dose but then it would realise that it is not good & not take anymore. There are some types of road salt that apparently contain some antifreeze which can be toxic to dogs.

Basically, heres how it goes(year by year): Well first we cant be sure that the winter flounder stocks are disappearing... Next, well there may be less winter flounder but lets wait and see if their is a recovery... Then, they havent returned to prior levels yet, perhaps somehting is wrong... Next, lets investigate possible reasons for their decline, but do nothing to help the population to recover... Further, well the investigations have yielded inconclusive results so more studies need to be undertaken before anything is put in stone... Finally, we dont know why the flounder are going away, however, we do not feel the best course of action is trying to repopulate, but actually to correct the problems of which we have no idea....

Nature. Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides Canadensis manages to withstand temperatures down to -30 degrees Celsius is reported by an international team of researchers led by Prof. Dr. Martina Havenith from the Department of Physical Chemistry II at the Ruhr-Universität in the journal PNAS. Together with American colleagues, the RUB-researchers showed that interactions between the antifreeze proteins and water molecules contribute significantly to protection against the cold. Previously, it was assumed that the effect was only achieved through direct contact of the protein with ice crystals. The team obtained the results through a combination of terahertz spectroscopy and molecular dynamics simulations.. Protein-ice interaction: locally and over longer distances. The structure of the fire beetle antifreeze proteins resembles a triangular prism. The ice binding surface of the "prism" ...

Antifreeze in the Gatorade was the preferred method by a Springfield, Mo., woman who fatally poisoned her husband and son and almost killed a daughter as well, Greene County authorities say. Diane Staudte, 51, has been charged with two counts of first-degree murder, one count of first-degree assault and one count of armed criminal action. A 22-year-old daughter, Rachel Staudte, also of Springfield, was charged Saturday with the same offenses.. Diane Staudte admitted Thursday to poisoning all three with antifreeze over a 14-month period, according to a probable cause statement. She told investigators that she killed her husband because she hated him and her son because he was "worse than a pest." She said she wanted to kill her 24-year-old daughter, Sarah Staudte, because the young woman "would not get a job and had student loans that had to be paid," the probable cause statement said. Her earlier story was that her husband, Mark Staudte, 61, hadnt been feeling well and suffered from seizures ...
The Warming and Irradiance Measurements (WARM) buoy is designed to collect coincident observations of temperature and light intensity. The buoy string has sensors collecting visible light measurements within the ice at 0.5 and 1.0 m from the ice surface and within the water column at 5, 10, 20 and 50 m from the ice surface. At the 5 m depth a Wetlabs Ecotriplet measures chlorophyll and dissolved organic material fluorescence. Thermistors are located at 2.5, 5.0, 7.5, 10, 15, 20 and 50 m. Two versions of the WARM buoy were deployed a 20 m version used on the shallow Chukchi Sea and a 50 m version deployed at the North Pole and Canada Basin.The buoy is deployed in early spring (March/April) by drilling a hole through the sea ice (~2 m thick) and feeding the tether through the ice. The surface float is anchored to the sea ice to prevent the buoy from slipping. In the summer the ice melts and the buoy is able to float in open water until the fall when it is frozen back into the ice. For more ...
Uptake of HNO3 onto cirrus ice may play an important role in tropospheric NOx cycling. Discrepancies between modeled and in situ measurements of gas-phase HNO3 in the troposphere suggest that redistribution and removal mechanisms by cirrus ice have been poorly constrained. Limited in situ measurements have provided somewhat differing results and are not fully compatible with theory developed from laboratory studies. We present new airborne measurements of HNO3 in cirrus clouds from anvil outflow made during the Tropical Composition, Cloud, and Climate Coupling Experiment (TC4). Upper tropospheric (|9 km) measurements made during three flights while repeatedly traversing the same cloud region revealed depletions of gas-phase HNO3 in regions characterized by higher ice water content and surface area. We hypothesize that adsorption of HNO3 onto cirrus ice surfaces could explain this. Using measurements of cirrus ice surface area density and some assumptions about background mixing ratios of gas-phase HNO3,

If this is a 16-valve DOHC engine then I would say that your head gasket is blown. Check your oil to see if their is a milky substance in it. Usually the milky substance is at the bottom of the oil dipstick. On these engines blowing the head gasket does not mean you will overheat. On my 2.5 DOHC engine the head gasket blew between cylinders 2 and 3 which allowed coolant to get into the cylinders and it basically burned it during combustion. If this is happening you should notice a white puff of smoke when you accelerate hard or when you first turn the car on. White smoke is not normal exhaust color and if you have this then you have a major repair bill on your hands ...

Psychrophilic organisms produce AFPs in order to prevent ice growth during freezing. Some studies have demonstrated that these proteins are extremely effective in the inhibition of recrystallization of ice even at very low concentrations [49]. However, their working mechanism is not well understood. Moreover, their properties offer the opportunity to exploit AFPs for biotechnological applications, especially in food industry. In frozen food products, freezing provides a multitude of small ice crystals, but it is also important to prevent the formations of large ice crystals [50]. AFPs from Antarctic bacteria GU1.7.1, GU3.1.1 and AFP5.1 were able to reduce the damage associated to ice, probably through the reduction of the size of large ice crystals in buffer solution. This phenomenon was evidenced when zucchini and cucumbers tissues were treated with a commercial and bacterial AFPs, where small pore were (red asterisk Figs. 1, 2) formed on plant cell walls of treated tissues in comparison to the ...
Press Release issued May 15, 2017: Anti-freeze coolants are used in automobiles, HVAC systems, and heat exchangers to facilitate heat transfer process in adverse cold weather conditions. Also, they prevent overheating of the vehicle in summer. These are antifreeze agents or chemicals that are added in water in a certain proportion. This mixture is called an anti-freeze coolant. Antifreeze coolants ensure workability and performance of engines and heat exchangers. Chemicals predominantly used as anti-freeze agents include propylene glycol, ethylene glycol, methanol, and glycerol. Adverse cold climatic conditions and automotive demand from relatively colder regions across the world maintain stable volumes of demand across the world. Other applications of antifreeze coolants are found in aerospace, industrial applications, and the electronics industry. Typical application in aerospace includes development of anti-icing and de-icing materials.
Adults mainly inhabit coral reefs, sometimes forming large aggregations, which are mostly stationary during the day. Juveniles occur in seagrass beds, also in mixed sand and coral habitats of shallow sheltered reefs (Ref. 1602). Sub-adults commonly form very large schools that are stationary or drift slowly along slopes during the day. Large individuals along coastal slopes at moderate depths (Ref. 48635). Benthopelagic (Ref. 58302). Feed on fishes, and a variety of invertebrates including shrimps, crabs, lobsters, stomatopods, cephalopods, echinoderms and ophiuroids (Ref. 55). ...

Ice-binding proteins (IBPs), a unifying name for antifreeze proteins, recrystallization inhibition proteins, and ice nucleating proteins, are found in organisms living in cold ecosystems where ice is present. Organisms from many branches of the tree of life use IBPs to embrace the consequences of freezing by several strategies such as preventing freezing or tolerating it. The program consists of plenary lectures, oral presentations, poster sessions, and an excursion.
Oh well, whatever, nevermind. He isnt a Didion fan, and thats okay. I am not a fan of Dave Eggers writing. I find Pynchon unreadable. This doesnt mean I am free to dismiss them, or their influence, out of hand. People writing seriously about reading, writing, and writers have an obligation to know whats out there. To borrow an analogy from hockey, one of the things that made Gretzky great was his ability to envision the ice surface, and everybody on it. He played center. And he always, always knew where his guys were--Kurri, McSorley, Messier, Coffey. He could pass to any of them without raising his head. He knew all the angles, the give in the boards, the furthest corners of the ice. He hung out behind the opposing net, moving back and forth, until with one sudden move the puck was in the net and the goalie cursing wildly. All this from a physically unprepossing man with the gift of great hands who saw the ice the way we wordy types should view the literary landscape ...

Antifreeze proteins (AFPs) are a unique class of proteins that bind to growing ice crystal surfaces and arrest further ice growth. AFPs have gained a large interest for their use in antifreeze formulations for water-based materials, such as foods, waterborne paints, and organ transplants. Instead of commonly used colligative antifreezes such as salts and alcohols, the advantage of using AFPs as an additive is that they do not alter the physicochemical properties of the water-based material. Here, we report the first comprehensive evaluation of thermal hysteresis (TH) and ice recrystallization inhibition (IRI) activity of all major classes of AFPs using cryoscopy, sonocrystallization, and recrystallization assays. The results show that TH activities determined by cryoscopy and sonocrystallization differ markedly, and that TH and IRI activities are not correlated. The absence of a distinct correlation in antifreeze activity points to a mechanistic difference in ice growth inhibition by the ...
Very little is known about the mechanism of antifreeze action of antifreeze glycoproteins (AFGPs) present in Antarctic teleost fish. Recent NMR and CD studies assisted with total synthesis of synthetic AFGP variants have provided insight into the structure of short AFGP glycopeptides, though the observations did not yield information on the antifreeze mechanism of action. In this study, we use Hamiltonian replica exchange (HREX) molecular dynamics simulations to probe the structure and surrounding aqueous environments of both the natural (AFGP8) and synthetic (s-AFGP4) AFGPs. AFGPs can adopt both amphiphilic and pseudoamphiphilic conformations, the preference of which is related to the proline content of the peptide. The arrangement of carbohydrates allows the hydroxyl groups on terminal galactose units to form stable water bridges which in turn influence the hydrogen-bond network, structure, and dynamics of the surrounding solvent. Interestingly, these local effects lead to the perturbation of ...

Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL). The physical and chemical nature of the surfacial region of ice is greatly affected by solutes such as sodium halide salts. In this work, we studied the effects of sodium chloride and sodium bromide on the photolysis kinetics of harmine, an aromatic organic compound, in aqueous solution and at the surface of frozen salt solutions above the eutectic temperature. In common with other aromatic organic compounds we have studied, harmine photolysis is much faster on ice surfaces than in aqueous solution, but the presence of NaCl or NaBr--which does not affect photolysis kinetics in solution--reduces the photolysis rate on ice. The rate decreases monotonically with increasing salt concentration; at the concentrations found in seawater, harmine photolysis at the surface of frozen salt solutions proceeds at the ...
One was a lovely toy poodle which ingested poison in a North Vancouver park (Princess Park) this week-end. The other dogs in the household were also sick but, given the patients small size, the amount of poison he consumed, he did not survive. His presentation was extremely unusual case as the antifreeze (ethylene glycol) was laced with something else which made the detection more difficult. We were told by the family that poison is at times put out in the parks of North Vancouver for dogs and wildlife (bears, coyotes or raccoons). While we can not think who would be so misguided as to do this, we wish to warn the pet owners in that area.. We recently saw a cat who had been exposed to minoxidil (Rogaine). It is known to cause irreversible heart failure in cats. Whether there is some left on hands after applying it, or even if they like to nuzzle (or lick) the treated area or the bottle itself, they become exposed. As more compounds are available for topical treatments (to lessen side effects to ...

Words To Know:. notothenoids: the arctic ice fish. practical application: how organisms adapt through natural selection. superheating: solid is above its melting point but does not actually it to melt at this point. Origins: Fish in Antarctica have been forced to evolve natural antifreeze proteins to stay alive. These proteins are mainly found in the notothenoid fishes, which are found in freezing temperatures. Arthur DeVries discovered these fish, their ice- binding-proteins and also figured out how they work in the 1960s . The proteins bind to small crystals and also protect cells by binding to their cell membranes. They are anti-freezing proteins that allow fish to survive and adapt to harsh and cold conditions of arctic waters.. Recent Discoveries:. Paul Cziko, among other researchers in the United States and New Zealand, published in The Proceedings of the National Academy of Sciences that these anti freeze proteins are also anti melting. Cziko and his team wanted to understand the ...

Certain Arctic and Antarctic ectotherm species have developed strategies for survival under low temperature conditions that, among others, consist of antifreeze glycopeptides (AFGP). AFGP form a class of biological antifreeze agents that exhibit the ability to inhibit ice growth in vitro and in vivo and, hence, enable life at temperatures below the freezing point. AFGP usually consist of a varying number of (Ala-Ala-Thr)(n) units (n=4-55) with the disaccharide beta-D-galactosyl-(1 -> 3)-alpha-N-acetyl-d-galactosamine glycosidically attached to every threonine side chain hydroxyl group. AFGP have been shown to adopt polyproline II helical conformation. Although this pattern is highly conserved among different species, microheterogeneity concerning the amino acid composition usually occurs; for example, alanine is occasionally replaced by proline in smaller AFGP. The influence of minor and major sequence mutations on conformation and antifreeze activity of AFGP analogues was investigated by ...
Our walking and running movement patterns require friction between shoes and ground. The surface of ice is characterised by low friction in several naturally occurring conditions, and compromises our typical locomotion pattern. Ice skates take advantage of this slippery nature of ice; the first ice skates were made more than 4000 years ago, and afforded the development of a very efficient form of human locomotion. This review presents an overview of the physics of ice surface friction, and discusses the most relevant factors that can influence ice skates dynamic friction coefficient. It also presents the main stages in the development of ice skating, describes the associated implications for exercise physiology, and shows the extent to which ice skating performance improved through history. This article illustrates how technical and materials development, together with empirical understanding of muscle biomechanics and energetics, led to one of the fastest forms of human powered locomotion.

  • Antarctic fish produce a range of such proteins, as the water temperatures can drop below 0 degrees Celsius. (edu.au)
  • Many animals that live in extremely cold climates produce proteins that act to prevent the formation of ice crystals in the bodily fluids of the organism. (edu.au)
  • This structure contains ~50% Ala and has a very similar fold to the wild type sequence, indicating that zinc-ligands and a few key hydrophobic residues are all that is required for structure. (edu.au)
  • In addition, Npc1 (Niemann-Pick disease, type C1), a 13 transmembrane-spanning protein containing a sterol-sensing domain, was also demonstrated to contribute early morphogenetic movements including epiboly and CE movements [ 7 ]. (ijbs.com)
  • This protein is tryptophan-containing mutant of BKLF F3 that retains native structure and function. (edu.au)
  • Therefore, both AFP4 proteins are essential for gastrulation of zebrafish embryos. (ijbs.com)
