Bucain, a potent neurotoxin isolated from the venom of the Malayan krait (Bungarus candidus), induces paralysis and death. Its crystal structure has been determined at 2.10 A resolution and based on the molecular topology and hydrophobicity profile is structurally classified as a three-fingered α-neurotoxin possessing a positively charged AChR-binding site.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
