Fasciculin
Fasciculins (FASs) are toxins produced by the snake green mamba. FASI and FASII are known to bind to acetylcholinesterase (AChE) and cause severe fasciculations. The images at the left and at the right correspond to one representative FAS, i.e. the crystal structure of Fasciculin 1 (1fas).
