Recombinant light chains of botulinum neurotoxins and light chain fusion proteins for use in research and clinical therapy

摘要

The present invention relates to the construction, expression, and purification of synthetic or recombinant light chain (LC) botulinum neurotoxin genes from all botulinum neurotoxin serotypes. The methods of the invention can provide 1.1 g of the LC per liter of culture. The LC product is stable and proteolytically active. Methods of using the products of the invention are described.
