The primary structure of a major polypeptide component from the venom of Naja melanoleuca.
The venom of the forest cobra, Naja melanoleuca, contains a number of homologous polypeptides containing between 60 and 71 amino acid resides. The primary structure of a major component (approx. 10% by weight of the crude venom) has been determined unambiguously. The molecule contians 61 amino acid residues and four disulphide bridges. It has not effect on neuromuscular transmission or the excitatory or inhibitory responses to acetylcholine of molluscan neurons. The molecule is similar to, but not identical with, the so-called cytotoxins VII2 and VII3 isolated, by others, from the same venom but reported to be minor components.
