Lethal Toxin Neutralizing Factor (LTNF) isolated from Opossum (Didephis virginiana) has been shown to exhibit anti-venom and anti-allergic property. The small synthetic peptide- LT10 derived from N-terminal of LTNF also showed this property in vivo. We applied molecular modeling, docking and molecular dynamic (MD) simulation techniques to compute the interaction of LT10 peptide with few snake venom enzymes, namely PLA2 from Naja naja and Atrolysin –C from Crotalus atrox. Our in silico interaction analyses provides molecular basis that might account for antivenom activity of LT10 peptide towards these two snake venom toxins. The understanding of such key molecular interactions could be useful for design and development of better anti-snake venom therapies.

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.
