一般描述

β-Amanitin belongs to the family of amatoxins.[1] Amanitins are made of bicyclic octapeptides.[2] β-Amanitin is composed of a carboxyl group and is acidic in nature.[3]

应用

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.[4]
  • to determine its concentration in urine samples by capillary zone electrophoresis (CZE).[5]
  • in the analysis of β-amanitin in toxic mushrooms by liquid chromatography coupled to time-of-flight mass spectrometry.[2]

生化/生理作用

Inhibits eukaryotic RNA polymerase II and III; does not inhibit RNA polymerase I or bacterial RNA polymerase; inhibits mammalian protein synthesis.
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.
