Background: Botulinum neurotoxins (BoNTs), produced by , are potent protein toxins that can cause botulism, which leads to death or neuroparalysis in humans by targeting the nervous system. BoNTs comprise three functional domains: a light-chain enzymatic domain (LC), a heavy-chain translocation domain (HC), and a heavy-chain receptor-binding domain (HC). The HC domain is critical for binding to neuronal cell membrane receptors and facilitating BoNT internalization via endocytosis.
