Polytheonamides are potently cytotoxic hypermodified ribosomal peptides that are produced by an uncultivated bacterium. Now, a bioinformatic mining strategy has enabled the development of a bacterial production host that can be cultivated in a laboratory. The host generates polytheonamide-like compounds within 2 days, and can efficiently introduce multiple d-amino acids, asparagine N-methylations and C-methyl groups into various peptides.
