Beta-Scorpion Toxin folded in the periplasm of E.coli

Template:ABSTRACT PUBMED 23999087

Function

[SIXE_HOTJU] Excitatory insect toxins induce a spastic paralysis. They bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. This toxin is active only on insects.
