Amanitins
Amanitin may refer to several related amatoxins: * α-Amanitin * β-Amanitin * γ-Amanitin * ε-Amanitin See also * Amatoxin, a class of toxic compounds that include the amanitins * Amanin Amanin is a cyclic peptide. It is one of the amatoxins, all of which are found in several members of the mushroom genus ''Amanita''. Toxicology Like other amatoxins, amanin is an inhibitor of RNA polymerase II. Upon ingestion, it binds to the ...

Amatoxin
Amatoxin is the collective name of a subgroup of at least nine related toxic compounds found in three genera of poisonous mushrooms (''Amanita'', ''Galerina'' and ''Lepiota'') and one species (Conocybe filaris) of the genus ''Conocybe''. Amatoxins are lethal in even small doses, as little as half a mushroom, including the immature 'egg' form which appears quite different from the fully-grown mushroom. Although laboratory analysis has found that the spores contain as little as 3% the toxin concentration of the main mushroom body, anecdotes have been repeated in field guides that claim foragers have fallen ill from spores alone after collecting but then discarding toxic Amanitas, unknowingly leaving their spore dust on the remaining harvest. Unlike many ingested poisons, they cannot be destroyed by heat without destroying the mushrooms beyond edibility first, so cooking the poisonous mushrooms does not diminish their lethality. Structure The compounds have a similar structure, tha ...
