Selection of metabolites produced by NRPS-like enzymes. a The terpenylquinone didemethyltasterriquinone D, the furanone aspulvinone E, the butyrolactone butyrolactone IIa and the dioxolanone phenguignardic acid with its related compound guignardic acid. b Monohydroxylation of the terphenylquinone polyporic acid leads to ascocorynin and a second hydroxylation to atromentin. Alternatively, while polyporic acid is produced from two molecules of phenylpyruvate (PP), ascocorynin can be synthesised from one molecule of phenylpyruvate and one molecule of p-hydroxyphenylpyruvate (p-OH-PP), and atromentin can be produced from the condensation of two molecules of p-hydroxyphenylpyruvate
