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 at Goethe University have now succeeded in changing these enzymes so that entirely new natural products, or even libraries of natural products, can be produced by microorganisms.
