The <scene name='Sandbox/Ache_1fss/6'>residues Thr8, Arg27, Met33 and Val34</scene> are present on two loops of the toxin FAS-II.
The residues <scene name='Sandbox_250/Ache_fas2/3'>Thr8, Met33, Arg27 and Val34</scene> are present on two loops of the toxin FAS-II.


When FAS-II <scene name='Sandbox/Ache_1fss/7'>binds</scene> to AChE, Arg27 and Met33 interact with trp279 of the Peripheral Anionic Site, while Val34 and Thr8 interact with tyr70 of the Peripheral Anionic Site. Once this interaction occurs, the entrance of the gorge is <scene name='Sandbox_250/Ache_fas2/1'>covered</scene> such that acetylcholine may not enter.
