Conformational Features of the Dippu-AST 8 Neuropeptide from the Cockroach Diploptera punctata
Abstract:Spatial structure and conformational properties of the Dippu-AST 8 (allatostatin III) neuropeptide have been investigated by the molecular mechanics method. The conformational energy and geometrical parameters corresponding to the low-energy states of the molecule are obtained. A single backbone conformation with a very restricted set of Ser 3, Phe 4 and Leu 9 amino acids positions is observed for Dippu-AST 8 neuropeptide.

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.
