Figure 3From: Predicted class-I aminoacyl tRNA synthetase-like proteins in non-ribosomal peptide synthesisSimplified scheme showing the core reactions catalyzed by the enzymatic systems described in this work. The figure shows reaction schemes for the biosynthesis of the cyclopeptide albonoursin, the siderophore aerobactin, and possible substrates of enzymes encoded by the systems based on the MtRS paralogs and reactions they could potentially catalyze.Back to article page
