Background: BoNT-D Light Chain

BoNT-D LC (Botulinum neurotoxin serotype D light chain) is a 50-55 kDa member of the peptidase M27 family of molecules. It is the product of Clostridium botulinum, and inhibits acetylcholine release from neuromuscular junctions. This is accomplished by toxin internalization with subsequent cleavage of synaptobrevin, thus blocking synaptic vesicle fusion with the presynaptic membrane. Notably, BoNT-D is not toxic to human cells. BoNT/D precursor is 1276 amino acids (aa) in length. Following internalization and precursor proteolytic cleavage, it assumes a mature form that shows a disulfide-linked 442 aa light chain/enzyme N-terminus, and a 834 aa heavy chain/receptor-binding C-terminus. The 100 kDa heavy chain creates a channel within the endosome that allows for redox rupture of the disulfide bond and entry of the light chain into the cytosol. Covalent attachment of cargo molecules to the N-terminus is used to transport molecules into the cytosol. The D light chain shares less that 50% aa identity with the other botulinum serotype light chains.
