title: The amino acid sequence of protein CM-3 from Dendroaspis polylepis polylepis (black mamba) venom.
abstract: Protein CM-3 from Dendroaspis polylepis polylepis venom was purified by gel filtration and ion exchange chromatography. It comprises 65 amino acids including eight half-cystines. The complete amino acid sequence of protein CM-3 has been elucidated. The sequence (residues 1-50) resembles that of the N-terminal sequence of the subunits of a synergistic type protein and residues 51-65 that of the C-terminal sequence of an angusticeps type protein. Mixtures of protein CM-3 and angusticeps type proteins showed no apparent synergistic effect, in that their toxicity in combination was no greater than the sum of their individual toxicities.
