scorpion toxins

scorpion toxins
Polypeptide toxins (7 kD) with four disulphide bridges. The a -toxins are found in venom of Old World scorpions, b -toxins in those of the New World. Bind with high affinity to the voltage-sensitive sodium channel of nerve and muscle ( a and b toxins bind to different sites).
