ClassSmall Molecule
DescriptionPatulin is found in pomes. Mycotoxin, found as a contaminant of foods, e.g. apple juice. Sometimes detd. in apple juice Patulin is a mycotoxin produced by a variety of molds, particularly Aspergillus and Penicillium. It is commonly found in rotting apples, and the amount of patulin in apple products is generally viewed as a measure of the quality of the apples used in production. It is not a particularly potent toxin, but a number of studies have shown that it is genotoxic, which has led to some theories that it may be a carcinogen, though animal studies have remained inconclusive. Patulin is also an antibiotic. Several countries have instituted patulin restrictions in apple products. The World Health Organization recommends a maximum concentration of 50 ug/L in apple juice. Patulin has been shown to exhibit apoptotic and antibiotic functions (5, 6). Patulin belongs to the family of Pyrans. These are compounds containing a pyran ring, which is a six-member heterocyclic, non-aromatic ring with five carbon atoms, one oxygen atom and two ring double bonds.

Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (3)
Mechanism of ToxicityPatulin's strong affinity to sulfhydryl groups enables to to inhibit a number of enzymes, including succinate dehydrogenase, alcohol dehydrogenases, ATPases, acetylcholinesterase, aldolases, protein tyrosine phosphatases, RNA polymerases, aminoacyl-tRNA synthetase, ribonuclease H, and lactate dehydrogenase. This widespread enzyme inhibition has a number of effects, including inhibition of aerobic respiration, inhibition of RNA synthesis, and inhibition of protein synthesis. Patulin also affects some aspects of membrane permeability and causes DNA-strand breakage and chromosomal aberrations, likely contributing to it's genotoxicity. Patulin may also cause the development of allergies by inhibiting interferon-gamma production. Mycotoxins are often able to enter the liver and kidney by human organic anion transporters (hOATs) and human organic cation transporters (hOCTs). They can also inhibit uptake of anions and cations by these transporters, interefering with the secretion of endogenous metabolites, drugs, and xenobiotics including themselves. This results in increased cellular accumulation of toxic compounds causing nephro- and hepatotoxicity. (14, 1, 2)
MetabolismMetabolism of patulin is limited. No metabolic products have been identified. It is quite likely that the metabolic fragments or conjugated metabolites of patulin either are bound to the cell membrane or become incorporated into the cellular components. (14)
Toxicity ValuesLD50: 29-48 mg/kg (Oral, Mouse) (15) LD50: 10 mg/kg (Subcutaneous, Mosue) (15) LD50: 5.7-8.17 mg/kg (Intraperitoneal, Mouse) (15) LD50: 8.57 mg/kg (Intravenous, Mouse) (15)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)3, not classifiable as to its carcinogenicity to humans. (11)
Uses/SourcesPatulin is a mycotoxin produced by a variety of molds, particularly Aspergillus and Penicillium. Although patulin can occur in many molding fruits, grains and other foods, the major source of patulin contamination is in apples with brown rot, and in apple cider or apple juice. Patulin is also an antibiotic. (13, 14)
Minimum Risk LevelThe World Health Organization recommends a maximum concentration of 50 µg/kg (50 ppb) in juices. (15)
Health EffectsAnimals studies have shown patulin to cause gastrointestinal hyperemia, distension, hemorrhage and ulceration. It has also been shown to be immunotoxic, and neurotoxic. (15, 16)
SymptomsSkin irritation occurs in cases of topical exposure. Patulin is also a stomach irritant and causes nausea and vomiting if ingested. (16)
TreatmentSymptomatic and supportive care is the mainstay of therapy. (4)

General Function:
Ubiquitin protein ligase binding
Specific Function:
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB1 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template. At the start of transcription, a single-stranded DNA template strand of the promoter is positioned within the central active site cleft of Pol II. A bridging helix emanates from RPB1 and crosses the cleft near the catalytic site and is thought to promote translocation of Pol II by acting as a ratchet that moves the RNA-DNA hybrid through the active site by switching from straight to bent conformations at each step of nucleotide addition. During transcription elongation, Pol II moves on the template as the transcript elongates. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing. Acts as an RNA-dependent RNA polymerase when associated with small delta antigen of Hepatitis delta virus, acting both as a replicate and transcriptase for the viral RNA circular genome.
