[Isolation of 6 subunits of scorpion, Androctonus australis garzonii, hemocyanin]. 1976

J Lamy, and J Lamy, and J F Pensec, and J Weill

A method for the purification of the 5 sub-units 5 S and of a 7 S sub-unit of the haemocyanin of the Scorpion Androctonus australis garzonii is reported. It includes preparation of crude haemocyanin, dissociation in 1 M urea in the absence of divalent cations, starch gel electrophoresis and A 50 DEAE "Sephadex" separation. All the sub-units are homogeneous with regard to ultracentrifugation and polyacrylamide gel electrophoresis. The yield variers from 7 to 20 per cent according to each fraction.

UI	MeSH Term	Description	Entries
D010446	Peptide Fragments	Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.	Peptide Fragment,Fragment, Peptide,Fragments, Peptide
D006433	Hemocyanins	Metalloproteins that function as oxygen transport proteins in the HEMOLYMPH of MOLLUSKS and ARTHROPODS. They are characterized by two copper atoms, coordinated with HISTIDINE residues, that reversibly bind a single oxygen molecule; they do not contain HEME groups.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012605	Scorpions	Arthropods of the order Scorpiones, of which 1500 to 2000 species have been described. The most common live in tropical or subtropical areas. They are nocturnal and feed principally on insects and other arthropods. They are large arachnids but do not attack man spontaneously. They have a venomous sting. Their medical significance varies considerably and is dependent on their habits and venom potency rather than on their size. At most, the sting is equivalent to that of a hornet but certain species possess a highly toxic venom potentially fatal to humans.

D046911	Macromolecular Substances	Compounds and molecular complexes that consist of very large numbers of atoms and are generally over 500 kDa in size. In biological systems macromolecular substances usually can be visualized using ELECTRON MICROSCOPY and are distinguished from ORGANELLES by the lack of a membrane structure.
