Biosynthesis of Antroquinonol and 4-Acetylantroquinonol B via a Polyketide Pathway Using Orsellinic Acid as a Ring Precursor in Antrodia cinnamomea.
    Journal of agricultural and food chemistry, 2017, Jan-11, Volume: 65, Issue:1

    Antroquinonol (AQ) and 4-acetylantroquinonol B (4-AAQB), isolated from the mycelium of Antrodia cinnamomea, have a similar chemical backbone to coenzyme Q (CoQ). Based on the postulation that biosynthesis of both AQ and 4-AAQB in A. cinnamomea starts from the polyketide pathway, we cultivated this fungus in a culture medium containing [U-

Identification of the orsellinic acid synthase PKS63787 for the biosynthesis of antroquinonols in Antrodia cinnamomea.
    Applied microbiology and biotechnology, 2017, Volume: 101, Issue:11

    Antrodia cinnamomea, an endemic basidiomycete used as a health food in Taiwan, is known to synthesize antroquinonols, which were reported to have notable medicinal potential in oncology and immunology. However, the biosynthetic pathway of these compounds is currently unclear. Our previous study showed that a pks63787 knockout mutant of A. cinnamomea (∆pks63787) is deficient in the biosynthesis of several aromatic metabolites. In this study, we pointed by phylogenetic analysis that pks63787 likely encodes an orsellinic acid synthase. Moreover, amendment of the cultural medium with orsellinic acid not only restores the ability of ∆pks63787 to produce its major pigment and other deficient metabolites, e.g., antroquinonols, but also enhances the productivity of several antroquinonols, including two new compounds 2 and 3. These results provide direct evidence that the PKS63787 is involved in the biosynthesis of antroquinonols and confirmed our hypothesis that the 6-methylcyclohexenone moiety was synthesized via the PKS63787-mediated polyketide pathway. In conclusion, PKS63787 might function as orsellinic acid synthase and orsellinic acid is an important precursor indispensable for the biosynthesis of the major pigment and antroquinonols in A. cinnamomea. To facilitate further basic or applied study, a putative biosynthesis pathway map of antroquinonols is proposed.
