The patulin biosynthesis is one of model pathways in an understanding of secondary metabolite biology and network novelties in fungi. However, molecular regulation mechanism of patulin biosynthesis and contribution of each gene related to the different catalytic enzymes in the biochemical steps of the pathway remain largely unknown in fungi. In this study, the genetic components of patulin biosynthetic pathway were systematically dissected in Penicillium expansum, which is an important fungal pathogen and patulin producer in harvested fruits and vegetables. Our results revealed that all the 15 genes in the cluster are involved in patulin biosynthesis. Proteins encoded by those genes are compartmentalized in various subcellular locations, including cytosol, nucleus, vacuole, endoplasmic reticulum, plasma membrane and cell wall. The subcellular localizations of some proteins, such as PatE and PatH, are required for the patulin production. Further, the functions of eight enzymes in the 10-step patulin biosynthetic pathway were verified in P. expansum. Moreover, velvet family proteins, VeA, VelB and VelC, were proved to be involved in the regulation of patulin biosynthesis, but not VosA. These findings provide a thorough understanding of the biosynthesis pathway, spatial control and regulation mechanism of patulin in fungi. << Less

Patulin biosynthesis: the metabolism of phyllostine and isoepoxydon by cell-free preparations from Pencillium urticae.
Sekiguchi J., Gaucher G.M.
Cell-free extracts of Penicillium urticae (NRRL 2159A), and its Pat-mutants, J2, J1, and S11, were found to contain significant NADP-dependent isoepoxydon dehydrogenase activity. This reversible interconversion of the epoxides (-)-phyllostine and (+)-isoepoxydon occurred optimally at pH 5.8 and wa ... >> More
Cell-free extracts of Penicillium urticae (NRRL 2159A), and its Pat-mutants, J2, J1, and S11, were found to contain significant NADP-dependent isoepoxydon dehydrogenase activity. This reversible interconversion of the epoxides (-)-phyllostine and (+)-isoepoxydon occurred optimally at pH 5.8 and was completely inhibited by 1 mM p-chloromercuribenzoate (PCMB). The cytosol enzyme possessed specificity for both substrate and cofactor since neither (+)-epoxydon, an epimer of (+)-isoepoxydon, nor NADH was utilized. Cell extracts of the parent and of mutant J2, which is blocked before the epoxides in the patulin pathway, were found to convert phyllostine and isoepoxydon to a number of unknown metabolites which appeared as yellow spots on thin-layer chromatograms after spraying with a chromogenic reagent. Extracts of mutant J1 were unable to carry out this conversion, while whole cells of mutant S11 accumulated what appeared to be these same 'yellow' compounds. Since PCMB-treated extracts of J2 converted phyllostine but not isoepoxydon to these new metabolites, phyllostine appeared to be their more immediate precursor. The relative positions of isoepoxydon and phyllostine in the patulin pathway are discussed. << Less
