The pyr cluster is responsible for the biosynthesis of pyranonigrin A. (A) The pyr cluster identified from P. thymicola IBT 5891. orf1 encodes IMPDH, pyrA encodes PKS-NRPS, pyrB encodes P450, pyrC encodes flavin-dependent monooxygenase, pyrD encodes hydrolase, orf2 encodes flavin binding oxidoreductase, orf3 encodes GMC oxidoreductase. (B) Characterization of pyrA in A. nidulans A1145. Shown are chromatograms of extracts from: i) A. nidulans expressing pyrA; ii) A. nidulans containing the control vector. (C) Reconstitution of pyr cluster in A. nidulans A1145. Shown are chromatograms of extracts from: i) A. nidulans expressing the putative pyr cluster; ii) A. nidulans containing control vectors.
