[[https://www.uniprot.org/uniprot/BXB_CLOBO BXB_CLOBO]] Botulinum toxin acts by inhibiting neurotransmitter release. It binds to peripheral neuronal synapses, is internalized and moves by retrograde transport up the axon into the spinal cord where it can move between postsynaptic and presynaptic neurons. It inhibits neurotransmitter release by acting as a zinc endopeptidase that cleaves the '76-Gln-|-Phe-77' bond of synaptobrevin-2.

== Publication Abstract from PubMed ==
Clostridium botulinum neurotoxins are among the most potent toxins to humans. The crystal structures of intact C. botulinum neurotoxin type B (BoNT/B) and its complex with sialyllactose, determined at 1. 8 and 2.6 A resolution, respectively, provide insight into its catalytic and binding sites. The position of the belt region in BoNT/B is different from that in BoNT/A; this observation presents interesting possibilities for designing specific inhibitors that could be used to block the activity of this neurotoxin. The structures of BoNT/B and its complex with sialyllactose provide a detailed description of the active site and a model for interactions between the toxin and its cell surface receptor. The latter may provide valuable information for recombinant vaccine development.
