Freedom of expression : A synthetic route to metabolites

Summary

Microbial specialized metabolites play key roles in microbiome interactions, but their biosynthetic pathways are difficult to characterize. In this issue, Patel et al. (2022) describe new technologies for the computer-aided redesign of gene clusters to facilitate heterologous expression across diverse hosts and showcase their utility by identifying a new class of microbiome-derived nucleotide metabolites.
