Antitumour activity of Helix hemocyanin against bladder carcinoma permanent cell lines
Biotechnology & Biotechnological Equipment, 2019 Hemocyanins are oxygen-transporting glycoproteins in molluscs and arthropods. In this study, we assayed the biomacromolecules from the molluscs Helix lucorum (HlH), Rapana venosa (RvH) and Megatura crenulata (KLH) including their functional units (FUs ...

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.

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates
Chemistry – A European Journal, EarlyView.ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Insect Molecular Biology, EarlyView.RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

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.

Antimicrobial Activity of Molluscan Hemocyanins from Helix and Rapana Snails
, 2016 For the first time the antimicrobial activities of hemocyanins from the molluscs Rapana venosa (RvH) and Helix aspersa (HaH) have been tested. From the hemolymph of the garden snail H.
