Expression, Renaturation and Functional Analysis of an Excitatory Insect-Specific Toxin from Scorpion Buthus martensii Karsch
Abstract:The cDNA of BmK IT-AP, an excitatory insect toxin from the scorpion Buthus martensi Karsch that has an analgesic effect on mammalian cells, was expressed in E. coli in the form of an inclusion body. Following denaturation and reduction, the recombinant protein was renatured and purified by liquid chromatography. The authenticity of the recombinant product was confirmed by bioassay and its electrophysiological effect on insect sodium channel.

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.
