Enzyme engineering lets us play with new building blocks in non-ribosomal peptide synthesis

In a recent issue of Nature Chemical Biology, Folger et al. demonstrated a high-throughput approach for engineering peptide bond forming domains from non-ribosomal peptide synthesis. A non-ribosomal peptide synthetase module from surfactin biosynthesis was reprogrammed to accept a fatty acid substrate into peptide biosynthesis, thus illustrating the potential of this approach for generating novel bioactive peptides.
