Crystal Structure of apo form (Zinc removed) of the Botulinum Neurotoxin Type C Light ChainCrystal Structure of apo form (Zinc removed) of the Botulinum Neurotoxin Type C Light Chain
[BXC1_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 syntaxin.
