General description

Patulin is a mycotoxin produced by a variety of molds, such as, Aspergillus and Penicillium. It is commonly found in apples. It is used as an inhibitor of potassium uptake and as an inducer of ion flux across cell membranes, potentially involving Na+-K+ dependent ATPase and to induce intra- and intermolecular protein crosslinking.

Application

Patulin has been used:
  • to study patulin contamination of bottled wine
  • in DNA-damaging activity of patulin in Escherichia coli
  • in molecular cloning and functional characterization of two CYP619 cytochrome P450s involved in biosynthesis of patulin in Aspergillus clavatus

Biochem/physiol Actions

Mycotoxin with anti-bacterial, potassium uptake inhibitory, and possibly carcinogenic activities. It is used as an inhibitor of potassium uptake and as an inducer of ion flux across cell membranes, potentially involving Na+-K+ dependent ATPase and to induce intra- and intermolecular protein crosslinking.

Other Notes

Patulin is a frequently found food contaminant mainly produced by the fungi Aspergillus and Penicillium. Patulin is suspected to be clastogenic, mutagenic, teratogenic and in higher concentrations cytotoxic. Here, we investigate the mechanism of the patulin-induced genotoxicity. Chromosomal damage was
