Microorganisms often assemble natural products similar to product assembly lines. Certain enzymes, non-ribosomal peptide synthetases (NRPS), play a key role in this process. Biotechnologists have now succeeded in changing these enzymes so that entirely new natural products, or even libraries of natural products, can be produced by microorganisms.
