Proamanullin
Proamanullin is a minor cyclic peptide of the amatoxin family found in deadly Amanita mushrooms.
Where Does It Come From? (1)
Proamanullin is a naturally occurring cyclic peptide (amatoxin), found in Death cap and related Amanita mushrooms. It is flagged as toxic.
Research & Evidence
Proamanullin is a bicyclic octapeptide belonging to the amatoxin group produced by certain deadly Amanita mushrooms. It is structurally related to the well-known toxin alpha-amanitin. Despite a source tag suggesting otherwise, it is not a tryptamine or a psychedelic; the amatoxins are inhibitors of RNA polymerase II, the same mechanism that makes this mushroom family lethal. Proamanullin is a comparatively minor congener and is not well characterised on its own.
Toxicity & Safety
As a member of the amatoxin family, proamanullin should be regarded as part of a class of compounds responsible for fatal mushroom poisonings; amatoxins cause severe liver and kidney damage. These mushrooms have no safe use, and any suspected ingestion is a medical emergency.
