DescriptionPhallacin belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Phallacin is a very strong basic compound (based on its pKa). Phallacin is one of a group of toxins from the death cap (Amanita phalloides) known as phallotoxins. Phallacin is a potentially toxic compound. Moreover, they inhibit the ATP hydrolysis activity of F-actin. They bind specifically at the interface between F-actin subunits, locking adjacent subunits together. The phallotoxins consist of at least seven compounds, all of which have seven similar peptide rings, isolated from the death cap (Amanita phalloides). This leads to a decrease in the rate constant for the dissociation of actin subunits from filament ends, which essentially stabilizes actin filaments through the prevention of filament depolymerization. Phallotoxins bind actin, preventing its depolymerization and poisoning the cell. Hypovolemic shock; Gastrointestinal symptoms occur after a latent period and include abdominal pain, vomiting, and watery diarrhea.
