Extreme thermostability of tarantula hemocyanin [PDF]

FEBS Letters, 1995
Biotops with extreme temperatures such as deserts force animals to avoid or escape high temperatures by biochemical, behavioural or morphological adaptation. In this context we tested the resistance to heat of the oxygen carrier hemocyanin from the ancient tarantula Eurypelma californicum, which is found in arid zones of North America.

Copper isotope composition of hemocyanin

Journal of Trace Elements in Medicine and Biology, 2022
Copper is a metal that plays a central role in biology, for example, as co-factor in various redox enzymes. Its stable isotopic composition is being used as tracer of its transport in living organisms and as a biomarker for diseases affecting its homeostasis.

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider. [PDF]

Mol Ecol Resour
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

Inter-Subunit Dynamics Controls Tunnel Formation During the Oxygenation Process in Hemocyanin Hexamers

Frontiers in Molecular Biosciences, 2021
Hemocyanin from horseshoe crab in its active form is a homo-hexameric protein. It exists in open and closed conformations when transitioning between deoxygenated and oxygenated states.

Diversity, evolution, and function of myriapod hemocyanins

BMC Evolutionary Biology, 2018
Background Hemocyanin transports O2 in the hemolymph of many arthropod species. Such respiratory proteins have long been considered unnecessary in Myriapoda. As a result, the presence of hemocyanin in Myriapoda has long been overlooked.

Short-Term Estivation and Hibernation Induce Changes in the Blood and Circulating Hemocytes of the Apple Snail Pomacea canaliculata

Metabolites, 2023
States of natural dormancy include estivation and hibernation. Ampullariids are exemplary because they undergo estivation when deprived of water or hibernation when exposed to very low temperatures.

Revealing the Diverse Allergenic Protein Repertoire of Six Widely Consumed Crab Species: A Species-Specific Allergen in King Crab. [PDF]

Allergy
This study comprehended the allergen profiles of six edible crab species using proteomic and transcriptomic analyses and identified 11 putative allergens. King crab has a distinct protein and allergen profile, with the discovery of malate dehydrogenase as a novel king crab‐specific allergen registered as Para c 11.

The occurrence of hemocyanin in Hexapoda [PDF]

The FEBS Journal, 2009
Hemocyanins are copper‐containing, respiratory proteins that have been thoroughly studied in various arthropod subphyla. Specific O2‐transport proteins have long been considered unnecessary in Hexapoda (including Insecta), which acquire O2 via an elaborate tracheal system.

The diversity and evolution of chelicerate hemocyanins

BMC Evolutionary Biology, 2012
Background Oxygen transport in the hemolymph of many arthropod species is facilitated by large copper-proteins referred to as hemocyanins. Arthropod hemocyanins are hexamers or oligomers of hexamers, which are characterized by a high O2 transport ...
