    Copper and zinc dismetabolism in the mouse brain upon chronic cuprizone treatment

    Recent reports describe successful treatment using copper chelation therapy in neurodegenerative animal models. However, the success claimed for chelation therapy in neurodegenerative diseases is still rather ...

    Comparison of the X-ray absorption properties of the binuclear active site of molluscan and arthropodan hemocyanins

    The structural characteristics of oxy- and deoxy-hemocyanins have been investigated using X-ray absorption spectroscopy both in the near-edge (XANES) and for the first shell contribution in the EXAFS region. ...

    Copper Depletion/Repletion of the Catalytic Centre of Ceruloplasmin as Monitored by Light Absorption, Fluorescence, EPR and Atomic Absorption Spectra

    0.1 mM human ceruloplasmin (CP) was dialyzed against 25 mM KCN in Tris/HCl, pH=7.0, at 4°C for 2,4,6,22 and 28 hrs, then 16 hrs against 10 mM EDTA 12-hr dialysis without EDTA followed. Copper in CP was measure...

    Half-apo Derivatives of Hemocyanins

    A number of experimental evidences have indicated that the two copper ions in the site of hemocyanin (Hc) are differently shielded by the protein matrix, thus showing asymmetrical chemical behaviour (1, 2,3). ...

    Effects of Solvent Composition on Hemocyanin Conformation

    The conformation of proteins is due to the balance of the electrostatic and hydrophobic interactions which develop either within aminoacid side chains or between these and the solvent. All chemical and/or phys...

    Spectroscopic Characterization of a Co(II) Derivative of Carcinus maenas Hemocyanin

    The substitution of the metal with Co(II) is a useful technique for studying the structure of the active site of metalloproteins and metalloenzymes. As known, Co(II) ions have unique spectroscopic and magnetic...
