Fungal dirigent protein controls the stereoselectivity of multicopper oxidase-catalyzed phenol coupling in viriditoxin biosynthesis.

Paecilomyces variotii produces the antibacterial and cytotoxic ( M)-viriditoxin (1) together with a trace amount of its atropisomer ( P)-viriditoxin 1'. Elucidation of the biosynthesis by heterologous pathway reconstruction in Aspergillus nidulans identified the multicopper oxidase (MCO) VdtB responsible for the regioselective 6,6'-coupling of semiviriditoxin (10), which yielded 1 and 1' at a ratio of 1:2. We further uncovered that VdtD, an α/β hydrolase-like protein lacking the catalytic serine, directs the axial chirality of the products. Using recombinant VdtB and VdtD as cell-free extracts from A. nidulans, we demonstrated that VdtD acts like a dirigent protein to control the stereoselectivity of the coupling catalyzed by VdtB to yield 1 and 1' at a ratio of 20:1. Furthermore, we uncovered a unique Baeyer-Villiger monooxygenase (BVMO) VdtE that could transform the alkyl methylketone side chain to methyl ester against the migratory aptitude. << Less
