Research Abstract	Pyripyropene, produced by a fungus Aspergillus fumigatus, is a meroterpenoid that is expected to be developed as a cholesterol lowering drug. Among the pyripyropene biosynthetic gene cluster, a novel terpene cyclase was identified that resembled more like a transporter. In this study, detailed analysis of its active site residue was carried out. Besides, a second meroterpenoid biosynthetic gene cluster was identified from A. fumigatus as well as from a fungus Fusarium graminearum, which causes Fusarium head blight. The PKS among the second gene cluster in A. fumigatus was shown to produce TAL.
