Daurichromenic acid (DCA) is a meroterpenoid with anti-HIV activities that is isolated from Rhododendron dauricum L. We recently reported that DCA is biosynthesized and accumulated in the apoplast of glandular scales attached on the surface of young leaves of R. dauricum. In the present study, we
Rhododendron dauricum L., a flowering tree popular in Hokkaido, produces daurichromenic acid (DCA), a terpenophenol with a potent anti-HIV activity. The DCA-producing enzyme, named DCA synthase, could be detected in the soluble protein fraction prepared from the young leaves of R. dauricum. DCA
Daurichromenic acid is a meroterpenoid with various pharmacological activities that is biosynthesized from grifolic acid in Rhododendron dauricum. Heterologous expression of grifolic acid synthases from Stachybotrys bisbyi and a daurichromenic acid synthase from R. dauricum in Aspergillus oryzae
Rhododendron dauricum produces daurichromenic acid, an anti-HIV meroterpenoid, via oxidative cyclization of the farnesyl group of grifolic acid. The prenyltransferase (PT) that synthesizes grifolic acid is a farnesyltransferase in plant specialized metabolism. In this study, we demonstrated that the
Daurichromenic acid (DCA) synthase catalyzes the oxidative cyclization of grifolic acid to produce DCA, an anti-HIV meroterpenoid isolated from Rhododendron dauricum We identified a novel cDNA encoding DCA synthase by transcriptome-based screening from young leaves of R. dauricum The gene coded for
