WebBoNTs are large neurotoxic proteins of ∼150 kDa that consist of a light chain (L-chain; 50 kDa) and a heavy chain (H-chain; 100 kDa) linked by a disulfide bond.. These two chains are linked by a single disulfide bond … WebAfter injection, Botox begins to bind to a group of proteins called SNARE. These proteins play a role in muscle movement because they're responsible for releasing a muscle-moving chemical called acetylcholine (ACh). The more SNARE proteins Botox binds up, the less ACh floating around, and the less muscle movement there will be.
