Descrizione generale

β-Amanitin belongs to the family of amatoxins. Amanitins are made of bicyclic octapeptides. β-Amanitin is composed of a carboxyl group and is acidic in nature.

Applicazioni

β-Amanitin from Amanita phalloides has been used:
  • as a calibration standard for the quantification of β-Amanitin using liquid chromatography-high resolution-mass spectrometry/mass spectrometry (LC-HR-MS/MS) method.
  • to determine its concentration in urine samples by capillary zone electrophoresis (CZE).
  • in the analysis of β-amanitin in toxic mushrooms by liquid chromatography coupled to time-of-flight mass spectrometry.

Azioni biochim/fisiol

Toxic constituent of the mushroom, Amanita phalloides, inhibits eukaryotic RNA polymerase II and III, but not RNA polymerase I or bacterial RNA polymerase. Inhibits mammalian protein synthesis.

A high-performance liquid chromatographic assay of alpha-amanitin and beta-amanitin in human serum, urine, or stomach washings is described. Sample preparation involves a chemical step with deproteinization and organic solvent treatment, and a selective cleanup and concentration step on reversed-phase prepacked
