Fig. 2: Biosynthesis of furochromone skeleton.

Functional characterization of SdPCS (a), SdPT (b), and SdPC (c). Shown are HPLC/UV chromatograms of enzyme catalysis reactions (λ = 280 nm), together with (+)-ESI-MS and MS/MS spectra of the products. Control, reaction mixtures incubated with boiled enzymes or microsomes.
