The arthropod hemocyanin superfamily is composed of phenoloxidases, hexamerins, pseudohemocyanins or cryptocyanins, and (dipteran) hexamerin receptors. Phenoloxidase are copper containing tyrosinases. These proteins are involved in the process of sclerotization of arthropod cuticle, in wound healing, and humoral immune defense. Phenoloxidase is synthesized by zymogens and are activated by cleaving an N-terminal peptide. WebA hydrophobic area on the protein surface near the copper site is a common feature of the blue copper proteins ~Baker, 1994!. Since the copper site is thought to be the region where the electron transfer takes place, the presence of a hydrophobic patch in this area might be related to the specific biological role played by the

WebHemocyanins are copper-containing respiratory pigments found in many mollusks (some bivalves, many gastropods, and cephalopods) and arthropods (many crustaceans, some arachnids, and the horseshoe crab, Limulus ). They are colourless when deoxygenated but turn blue on oxygenation. The copper is bound directly to the protein, and…. WebThe blue copper proteins have a beautiful blue colour, far more intense than that of the Cu(II) ion in water, but similar in hue. Caeruloplasmin has several of these functions, and is a blue colour, hence the recently … red dawn author

WebJan 1, 2001 · The blue copper proteins or cupredoxins are a group of proteins that exhibit a number of unusual properties, viz. a bright blue colour, a narrow hyperfine splitting in … WebThe spectroscopic and electrochemical properties of blue copper proteins are strikingly different from those of inorganic copper complexes in aqueous solution. Over three decades ago this unusual behavior was ascribed to constrained coordination in the folded protein; consistent with this view, crys … Copper coordination in blue proteins WebWe studied the coherent electron transport through metal–protein–metal junctions based on a blue copper azurin, in which the copper ion was replaced by three different metal ions (Co, Ni and Zn). Our results show that neither the protein structure nor the transmission at the Fermi level change significantly upon metal replacement. The discrepancy with … red dawn bjj
