Scyllatoxin
Scyllatoxin (Leiurotoxin I) is a peptide toxin, it can be isolated from the venom of the scorpion (Leiurus quinquestriatus hebraeus). Scyllatoxin is a blocker of small-conductance KCa (SK) channel. Scyllatoxin enhances both norepinephrine (NE) and epinephrine (Epi) release in vivo.

Biological Activity
For scyllatoxin, the Arg6 and Arg13 are essential for binding to the Ca2+-activated K+ channel protein and for the functional effect of the toxin[1]. For scyllatoxin, His31 is important for the binding activity of the toxin and for the induction of contractions on taenia coli[1].
