The diversity and evolution of chelicerate hemocyanins [PDF]
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 ...

The Structure of Arthropod Hemocyanins
Hemocyanins are large multi-subunit copper proteins that transport oxygen in many arthropods and molluscs. Comparison of the amino acid sequence data for seven different subunits of arthropod hemocyanins from crustaceans and chelicerates shows many highly conserved residues and extensive regions of near identity.

Antiviral activity of hemocyanins [PDF]
Hemocyanins are giant biological macromolecules acting as oxygen-transporting glycoproteins. Most of them are respiratory proteins of arthropods and mollusks, but besides they also exhibit protecting effects against bacterial, fungal and viral invasions.

Classification of polyphenol oxidases shows ancient gene duplication leading to two distinct enzyme types [PDF]
Summary: Polyphenol oxidases (PPOs) are coupled binuclear copper proteins that catalyze the oxidation of phenols. New functions of PPOs are continuously being discovered, latest with several fungal o-methoxy phenolases, which are active on lignin-derived

The evolution of hemocyanin genes in Tectipleura: a multitude of conserved introns in highly diverse gastropods [PDF]
Background Hemocyanin is the oxygen transporter of most molluscs. Since the oxygen affinity of hemocyanin is strongly temperature-dependent, this essential protein needs to be well-adapted to the environment.

Diverse immune functions of hemocyanins
Substantial evidence gathered recently has revealed the multiple functionalities of hemocyanin. Contrary to previous claims that this ancient protein is involved solely in oxygen transport within the hemolymph of invertebrates, hemocyanin and hemocyanin-derived peptides have been linked to key aspects of innate immunity, in particular, antiviral and ...

Preliminary Analysis of Hemocyanins in Hemolymph Plasma of Baikal Endemic Amphipods [PDF]
Two-dimensional electrophoresis of plasma hemolymph proteins of several endemic Baikal amphipod species showed that, as expected, hemocyanin is the main major protein in plasma of these species.

Hemocyanins of Muricidae: New 'Insights' Unravel an Additional Highly Hydrophilic 800 kDa Mass Within the Molecule. [PDF]
Hemocyanins are giant oxygen transport proteins that freely float within the hemolymph of most molluscs. The basic quaternary structure of molluscan hemocyanins is a cylindrical decamer with a diameter of 35 nm which is built of 400 kDa subunits ...
