The structure of arthropod hemocyanins.
Hemocyanins are large multi-subunit copper proteins that transport oxygen in many arthropods and molluscs. Comparison of the amino acid sequence data for seven different subunits of arthropodExpand

Complete amino-acid sequence of a functional unit from a molluscan hemocyanin (Helix pomatia).
From the beta c-hemocyanin (beta c-Hc) of the vineyard snail, Helix pomatia, the functional unit d (Mr approximately equal to 50,000-55,000) was isolated by limited proteolysis and gelExpand

Hemocyanins in spiders, XII. Dissociation and reassociation of Eurypelma hemocyanin.
The dissociation and reassembly of Eurypelma californicum hemocyanin was studied under various conditions of pH, ionic strength and protein, calcium and magnesium concentrations. The hemolymphExpand

Haemocyanins in spiders, III. Chemical and physical properties of the proteins in Dugesiella and Cupiennius blood.
The haemolymph of the tarantulas, Dugesiella (Eurypelma) californica and Dugesiella (Eurypelma) helluo contains high molecular weight haemocyanin (80-82% of total blood proteins) and a second proteinExpand

Hemocyanins in spiders, XVI[1]. Subunit topography and a model of the quaternary structure of Eurypelma hemocyanin.
Specific antibodies were prepared against the individual subunits of the hemocyanin isolated from the tarantula Eurypelma californicum. From the antibodies, the monovalent antigen-binding fragmentsExpand

Hemocyanins in spiders, IV[1]. Subunit heterogeneity of Eurypelma (Dugesiella) hemocyanin, and separation of polypeptide chains.
The hemocyanin of the North American tarantula Eurypelma californicum (Dugesiella californica) is dissociated at pH 9.6 into monomers (Mr about 70 000) and dimers (Mr about 140 000), which wereExpand

Hemocyanins in spiders, XIX. Complete amino-acid sequence of subunit d from Eurypelma californicum hemocyanin, and comparison to chain e.
The complete primary structure of subunit d of the hemocyanin from the tarantula Eurypelma californicum was determined by manual micro sequencing. Subunit d of Mr = 73000 is split about in the middleExpand
