A structural model for multimodular NRPS assembly lines
This viewpoint article focuses on the structures of the dissected catalytic domains of non-ribosomal peptide synthetases and how these structural details of the NRPS machinery, integrated in a didomain and an elongation module were used to generate a model for a multimodular NRPS assembly line.

Recent advances in the biosynthesis of unusual polyketide synthase substrates
Polyketides comprise a diverse class of natural products, with many important biological and pharmacological activities. Substrates functioning as starter units and extender units during their assembly significantly contribute to the chemical complexity exhibited by this class of natural products. This highlight provides an overview of the recent advances in understanding the diversity of these polyketide synthase (PKS) building blocks.

Recent advances in engineering nonribosomal peptide assembly lines
This reviews summarises progress towards the engineering of nonribosomal peptide synthetases (NRPS) from the expression of heterologous tailoring enzymes to direct modifications of the assembly lines to produce analogues. New techniques/tools for introducing changes are also examined.

Polyketide synthase and non-ribosomal peptide synthetase thioesterase selectivity: logic gate or a victim of fate?
Thioesterases (TEs) are product offloading enzymes from FAS, PKS, and NRPS complexes. We review the diversity, structure, and mechanism of PKS and NRPS TEs and analyze TE loading and release steps as possible logic gates with a view to predicting TE function in new pathways.
