Amanullin is a cyclic nonribosomal peptide. It is an amatoxin, all of which are found in several members of the Amanita genus of mushrooms. The oral LD50 of amanullin is approximately 20 mg/kg in mice, however it is non-toxic in humans.

Toxicology

Like other amatoxins, amanullin is an inhibitor of RNA polymerase II. Amanullin has a species dependent and specific attraction to the enzyme RNA polymerase II. Upon ingestion, it binds to the RNA polymerase II enzyme, effectively causing cytolysis of hepatocytes (liver cells).[1]
