Amantiina is part of a group of toxins called amatoxinswhich can be found in several mushrooms belonging to the genus Amanita. Some examples are the death cap Amanita phalloides and members of the destroying angel complex, which includes A.

The lethal dose of amanitoxins is 0. Contact with the eyes may result in irritation, corneal burns, and eye damage.

alpha-Amanitin – Wikipedia

Persons with pre-existing skin, eye, or central nervous systems disorders, impaired liver, kidney, or pulmonary function may be more susceptible to the effects of this substance. While it damages all organs, damage to the liver and heart result in fatalities. At the molecular level amanitin toxins cause damage to cells of these organs.


The toxins may also cause disruptions in the plasma alfaa resulting in organelles that are normally in the cytoplasm to be found in the extracellular matrix. In particular, William LipscombNobel laureate, greatly contributed to characterizing this protein.

Not only did Lipscomb determine how to successfully retrieve and purify this life-threatening protein, but he also determined the molecular structure by X-ray crystallography in a time before this science was widely utilized. This was first achieved by collecting Amanita phalloides fruiting bodies in New Jersey in These mushrooms were then dried for 24 hours and then ground in a blender with water.

The slurry created was homogenized further to break open any intact cells, and after this a brown syrup extract containing the toxins was collected. This extract was then taken through various separation methods to isolate the toxins themselves. The toxins were then desalted and taken through four different methods of sephadex and acidic protein purification. The crystallization and analysis were performed by Edward C.

Kostansek and William H. The flask was left open overnight and crystals formed as the ethanol evaporated. This is considered to be an incredibly easy crystallization to perform. From Wikipedia, the free encyclopedia.
