How does acetylcholine get released
WebThrough their proteolytic action on these proteins, botulinum toxins prevent exocytosis, thereby inhibiting the release of acetylcholine. There are 7 serotypes of this toxin-A, B, C1, D, E, F, and G-and each cleaves a different intracellular protein or the same target at distinct bonds. The separate cleavage sites in SNAP-25 for botulinum toxin ...
