Fig. 3From: Mutagenetic analysis of the biosynthetic pathway of tetramate bripiodionen bearing 3-(2H-pyran-2-ylidene)pyrrolidine-2,4-dione skeletonGene organization of bpd BGC (a) and the proposed biosynthetic pathway of compounds 1 and 2 (b). The proposed aminoacyl transthiolation between the BpdD and BpdC NRPS subunits is highlighted by a frame; The inactive A domain in BpdC is shown by white circleBack to article page
