From: Bifurcate evolution of quinone synthetases in basidiomycetes
Polyporic acid formation by chimeric quinone synthetases and subsequent phlebiopsin production by the heterologous host. Shown are UHPLC-MS analyses of ethyl acetate extracts of ppaA1:corA-expressing A. nidulans strains. For comparison, chromatograms of A. nidulans tPS19 and tStL04, expressing native ppaA1 and corA, respectively, are included. Analyzed peaks are indicated by numbered bars shaded in grey. Chromatograms were extracted at λ = 350 nm. Compound numbering: phlebiopsin A (1); phlebiopsin B (2); polyporic acid (3)
