clostridial neurotoxin(English)
- a family of closely related bacterial protein toxins, consist of seven antigenically distinguishable botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT). Each toxin is synthesized as a ~150 kDa single chain protein, but subsequently cleaved by specific clostridial or host proteases. Cleavage results in an N-terminal ~50 kDa light chain (LC) and a C-terminal ~100 kDa heavy chain (HC). Both chains remain attached via a single disulfide bond formed between cysteines at the C-terminus of the LC and the N-terminus of the HC, a peptide loop formed by the N-terminal ~55 amino acids of HC that wraps around the LC and further non-covalent interactions. Regarded as the most hazardous natural substances known. The 50% lethal doses for susceptible mammals including man amount to approximately one nanogram per kg of body weight
