Most molluscs have blue blood because their respiratory molecule is hemocyanin, a type-3 copper-binding protein that turns blue upon oxygen binding. Molluscan hemocyanins are huge cylindrical multimeric glycoproteins that are found freely dissolved in the hemolymph. The structure and evolution of molluscan hemocyanin have been studied for decades, but it required the recent progress in DNA sequencing, X-ray crystallography and 3D electron microscopy to produce a detailed view of their structure and evolution. Hemocyanin - Hc Hemocyanin - Hc - Structure, Deoxy – Hemocyanin, Oxy – Hemocyanin Dioxygen – Binding Hemocyanin Spectral data of Hemocyanin Met – 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. Hemocyanins are responsible for transporting O 2 in the arthropod and molluscan hemolymph.

In arthropod species, Hemocyanin-like proteins of Biomphalaria glabrata and full-length hemocyanins of other Tectipleura share the same gene structure Previous to this study, only the exon–intron architectures of two hemocyanin-like protein genes of Biomphalaria glabrata ( BgHcl -1, BgHcl -2) have been published for species of the clade of Tectipleura [ 22 ].

Hemocyanin structure

Gai et al. determined the first X-ray crystal structure of intact molluscan hemocyanin, which unveiled the architecture of the 3.8-MDa cylindrical supermolecule composed of hierarchically associated homologous functional units. 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.

These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O 2). They are second only to hemoglobin in frequency of use as an oxygen transport molecule. 2013-09-01 A hemocyanin of the tarantula Eurypelma californicum is made up of 4 hexamers or 24 peptide chains.

Hemocyanins are colourless in the reduced, or deoxygenated, state and blue when exposed to air or to oxygen dissolved in the blood. 2021-03-04 The crystal structure of T.pacificus hemocyanin was determined by the molecular replacement method using the wall region of the Cα model of Haliotis diversicolor hemocyanin (PDB: 3J32) as a search model combined with noncrystallographic symmetry (NCS) averaging (Figures 1 and S1, and Table 1).The revealed structure was a cylindrical decamer with five-fold symmetry, and consisted of a wall and 2009-03-17 structure of the hemocyanin Helix lucorum (HlH), species in the series of molluscan hemocyanins.
