met-hemocyanin, as deduced from the fitting of the first-shell extended X-ray absorption fine structure (EXAFS) data (Woolery et al., 1984). With the peroxide coordination mode in the Kitajima's model compounds, analogous to that deduced from X-ray crys- tallography on oxy-hemocyanin, there is no need to assume the This is the first X-ray structure of an unit from the wall of the molluscan hemocyanin cylinder. The crystal structure of RtH2e demonstrates molecular self-assembly of six identical molecules forming a regular hexameric cylinder. This suggests how the functional units are ordered in the wall of the native molluscan hemocyanins. Comparison of the Two Molluscan Hemocyanin Genes: Exon-Intron Structure. The structure of the HtH1 gene and the OdH G gene are compared schematically in Fig. 1.

Roles of the inner collar domains and carbohydrates, and evolutionary implications, are discussed in detail. Hemocyanin structure. • The oxygen binding centre is composed of a pair of copper atoms. Each Cu atom is bounded by 3 histidine ligands.An empty cavity exist between the Cu atoms. • The Cu is in +1 oxidation state in the deoxy form & it is diamagnetic in nature & so it is colourless. The crystal structure of Limulus polyphemus subunit type II hemocyanin in the deoxygenated state has been determined to a resolution of 2.18 A. Phase information for this first structure of a cheliceratan hemocyanin was obtained by molecular replacement using the crustacean hemocyanin structure of Panulirus interruptus. met-hemocyanin, as deduced from the fitting of the first-shell extended X-ray absorption fine structure (EXAFS) data (Woolery et al., 1984).

The basic molluscan hemocyanin quaternary structure is the decamer, a cylinder 35 nm in diameter and 18 nm in height, containing ten subunits with identical sequence. In its most simple but rarely seen form , the decamer is exclusively consisting of a wall (Fig. 2A).

In a biochemical breakthrough for molluscan hemocyanin, the first quaternary structure with atomic resolution is on the verge of solving the mystery of molluscan hemocyanin. Here we describe the latest information about the molecular structure, classification and evolution of the molecule, and the physiology of molluscan hemocyanin.

Although the respiratory function of hemocyanin is similar to that of hemoglobin, there are a significant number of differences in its molecular structure and mechanism. Whereas hemoglobin carries its iron atoms in porphyrin rings ( heme groups), the copper atoms of hemocyanin are bound as prosthetic groups coordinated by histidine residues. Abstract. Hemocyanin is an extracellular, blue protein that occurs in high concentrations in the blood of many arthropods, including spiders, scorpions, horseshoe crabs, crustaceans, and at least two centipedes. In a biochemical breakthrough for molluscan hemocyanin, the first quaternary structure with atomic resolution is on the verge of solving the mystery of molluscan hemocyanin. Here we describe the latest information about the molecular structure, classification and evolution of the molecule, and the physiology of molluscan hemocyanin. The basic molluscan hemocyanin quaternary structure is the decamer, a cylinder 35 nm in diameter and 18 nm in height, containing ten subunits with identical sequence.
