<unk>  is an inhibitory β-toxin and thus, a Na+ channel inhibitor. As with other mammal and insect toxins,<unk>  is classified according to species and mechanism of action.<unk>  is a 61-amino-acid protein derived from an 85-amino-acid precursor. The mature protein contains 8 cysteine residues that establish 4 disulfide bridges (4C-C). Despite its high homology with other depressant toxins,<unk>  differs from them at residues 6, 7 and 39, which is thought to be important in determining its unique function. Its lysine residue, at position 51, also has a special feature: it interacts with mammalian Na+ channels.<unk>  primary sequence 01 mklflllvis asmlidglvn adgyirgsng 31 ckvsclwgne gcnkeckafg ayygycwtwg 61 lacwceglpd dktwksesnt cggkk
