More Information
Summary:The present invention relates to a method for proteolytically processing a single-chain clostridial neurotoxin into a corresponding di-chain clostridial neurotoxin, the method comprising: providing a single-chain clostridial neurotoxin; and contacting the single-chain clostridial neurotoxin with furin; wherein the single-chain clostridial neurotoxin has an activation loop comprising or consisting of the polypeptide sequence Arg-Xaa-Xaa-Arg; and wherein furin hydrolyses a peptide bond of the activation loop thereby producing a di-chain clostridial neurotoxin. The invention also relates to engineered clostridial neurotoxins and methods for manufacturing the same, as well as related pharmaceutical compositions, nucleotide sequences, and therapeutic and cosmetic uses.
