Some members of this genus produce a conformationally-restricted glutamate analogue useful for reversible brain lesioning; a potent GABA-A (“GAB-uh A”) agonist derived from members of this genus has similar applications. A compound named for being discovered in this genus locks RNAPII’s (“R-N-A-P-two’s”) bridge helix into place, halting DNA translocation. Phallotoxins from this genus conjugated to rhodamine or eosin can be used to visualize muscle fibers because they specifically bind and stabilize F-actin. A species of this genus names a compound that acts as an agonist for a class of namesake G-protein-coupled acetylcholine receptors. Muscimol is responsible for the psychoactive effects of the most famous mushroom of this genus, which was often used as an entheogen. For 10 points, species muscaria and phalloides (“fal-LOY-deez”) are members of what fungal genus that contains red-and-white spotted fly agarics and toxic death caps? ■END■
ANSWER: Amanita [accept specific species like Amanita muscaria or Amanita phalloides; prompt on A. muscaria or A. phalloides or destroying angels by asking “what is the genus name?”; prompt on death caps or fly agarics until each is read by asking “what is the genus name?”; prompt on amatoxins or alpha-amanitin or beta-amanitin by asking “what genus is it named for?”] (The lesioning compounds are the glutamate analogue ibotenic acid and the GABA-A agonist muscimol.)
