This protein is scorpion toxin II from Androctonus austalis. It is a 64 residue protein that binds to mammalian sodium channels, causing paralysis and death at high enough doses. Most of the residues indicated to be crucial to binding to sodium channels are located on a knob at the lower left of the image. Positively charged amino acids are shown in red. Arg 62 and His 64 protrude furthest from the core of the protein. It is reasonable to expect such residues to be involved in binding to sodium channels, which usually handle positively-charged Na+ ions. Mutational analysis has shown that Asp 8 (blue) and Lys 58 (green) are likely to be critical to binding. Arg 18 is not in the same region as the rest of the binding residues, but probably has a major role in binding also. The purple segment is residues 9 through 12, which together with residue 8, form a structurally conserved loop found in many scorpion toxins. This image was made by J High, School of Biology, Georgia Tech, 1998.

蝎子入药是因为蝎毒，那蜜蜂呢？

记得有人特意让蜜蜂叮，据说可以不得关节炎什么的，不知道有没有人培养一种低毒的蝎子

蝎毒的主要成分是啥？通过体液（叮咬）和消化道（熬药）作用有啥区别？

据说蝎子跟蛇一样越小越毒。记得十几年前养殖蝎子好像挺流行的，到处都有那种培训班，过了一段就销声匿迹了。

吃过活蝎子，泡在酒里张牙舞爪的那种，一点味道也没有，远不如油炸的爬雪山蝎子。
