Genomic evidences for the existence of a phenylpropanoid metabolic pathway in Aspergillus oryzae.

Journal Article (Journal Article)

Plants interact with their environment by producing a diverse array of secondary metabolites. A majority of these compounds are phenylpropanoids and flavonoids which are valued for their medicinal and agricultural properties. The phenylpropanoid biosynthesis pathway proceeds with the basic C6-C3 carbon skeleton of phenylalanine, and involves a wide range of enzymes viz., phenylalanine ammonia lyase, coumarate hydroxylase, coumarate ligase, chalcone synthase, chalcone reductase and chalcone isomerase. Recently, bacteria have also been shown to contain homodimeric polyketide synthases belonging to the plant chalcone synthase superfamily linking the capabilities of plants and bacteria in the biosynthesis of flavonoids. We report here the presence of genes encoding the core enzymes of the phenylpropanoid pathway in an industrially useful fungus, Aspergillus oryzae. Although the assignment of enzyme function must be confirmed by further biochemical evidences, this work has allowed us to anticipate the phenylpropanoid metabolism profile in a filamentous fungus for the first time and paves way for research on identifying novel fungal flavonoid-like metabolites.
