epsilon-Amanitin or ε-amanitin is a Cyclic peptide. It is an amatoxin, all of which are found in several members of the Amanita genus of mushrooms. The oral LD₅₀ of ε-amanitin is approximately 0.1 mg/kg.

Toxicology

Like other amatoxins, ε-amanitin an inhibitor of RNA polymerase II. Upon ingestion, it binds to the RNA polymerase II enzyme which completely prevents mRNA synthesis, effectively causing cytolysis of hepatocytes (liver cells) and kidney cells.^[1]
