Abstract
A major component (S5C4) was purified from Jameson''s mamba [D. jamesoni kaimosae] by gel filtration on Sephadex G-50 and by ion-exchange chromatography on CM-cellulose. Protein S5C4 contains 60 amino acid residues and is cross-linked by 4 intrachain disulphide bridges. The complete primary structure of the protein was elucidated. The toxicities, the immunochemical properties, the sequence and the invariant amino acid residues of protein S5C4 resemble subgroup II of the D. angusticeps-type proteins.
