The neurotoxin secreted by Indian cobra (Naja naja) binds to acetylcholine receptor of nerve cells, which leads to a lump in the nerve impulse, ceases breathing, thereby causing the death of a person due to suffocation. These neurotoxins are small peptide with approximately 7 kDa. Homology modeling was performed to generate the 3D structure of neurotoxins (A, B, C and D) of N. naja, using the k...
Tetanus neurotoxin was depleted of its catalytic Zn2+ ion, and the apotoxin was reconstituted with different transition metal ions. The Mn2+- and Co2+-tetanus neurotoxins are highly active in the proteolysis of vesicle-associated membrane protein/synaptobrevin, the natural substrate of this toxin, whereas Cu2+ and Fe2+ minimally supported proteolytic activity. The visible absorbance spectrum of...
Elapid snake venom neurotoxins exert their effects through high-affinity interactions with specific neurotransmitter receptors. A novel murine gene, lynx1, is highly expressed in the brain and contains the cysteine-rich motif characteristic of this class of neurotoxins. Primary sequence and gene structure analyses reveal an evolutionary relationship between lynx1 and the Ly-6/neurotoxin gene fa...
