    Structural and functional heterogeneity of hemocyanin: intra- and inter-specific comparison in four species of portunid crabs (Crustacea: Portunidae)

    This work is focused on hemocyanin (Hc) heterogeneity at population level and on the biochemical characterization of the different subunit patterns. Two different approaches have been used: we have characteriz...

    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. ...

    Effects of environmental parameters on the oxygen consumption of four marine invertebrates: a comparative factorial study

    The oxygen consumption curves of two decapod crustaceans (Palaemon serratus, Penaeus monodon) and two prosobranch molluscs (Trunculariopsis trunculus, Nassarius mutabilis) have been detected in the entire pO2 in...

    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). ...
