Carboxylesterase; part of the gene cluster that mediates the biosynthesis of patulin, an acetate-derived tetraketide mycotoxin produced by several fungal species that shows antimicrobial properties against several bacteria (PubMed:19383676, PubMed:24334092).

The pathway begins with the synthesis of 6-methylsalicylic acid by the polyketide synthase (PKS) patK via condensation of acetate and malonate units (PubMed:19383676).

The 6-methylsalicylic acid decarboxylase patG then catalyzes the decarboxylation of 6-methylsalicylic acid to yield m-cresol (also known as 3-methylphenol) (PubMed:24334092).

These first reactions occur in the cytosol (By similarity).

The intermediate m-cresol is then transported into the endoplasmic reticulum where the cytochrome P450 monooxygenase patH converts it to m-hydroxybenzyl alcohol, which is further converted to gentisyl alcohol by the cytochrome P450 monooxygenase patI (By similarity).

The oxidoreductases patJ and patO further convert gentisyl alcohol to isoepoxydon in the vacuole (By similarity).

PatN catalyzes then the transformation of isoepoxydon into phyllostine (By similarity).

The cluster protein patF is responsible for the conversion from phyllostine to neopatulin whereas the alcohol dehydrogenase patD converts neopatulin to E-ascladiol (By similarity).

The steps between isoepoxydon and E-ascladiol occur in the cytosol, and E-ascladiol is probably secreted to the extracellular space by one of the cluster-specific transporters patC or patM (By similarity).

Finally, the secreted patulin synthase patE catalyzes the conversion of E-ascladiol to patulin (By similarity).

The role of the carboxylesterase patB in the patulin pathway was not determined yet and requires further study (By similarity).

Patulin was originally used as an antibiotic and specifically trialed to be used against the common cold, but it is no longer used for that purpose since it has been shown to induce immunological, neurological and gastrointestinal effects (PubMed:15082620). Genotoxic effects of patulin with dose-dependent increase in DNA strand breaks in brain, liver and kidneys have been detected in mice (PubMed:22222931). However, more recently, it has been proposed that patulin might also have anti-tumor properties (PubMed:26619846).3 Publications
