Synthetic biology for natural product drug production and engineering.

Natural products continue to provide privileged scaffolds for drug discovery. However, challenges in supply and structure diversification can limit development. Here, we discuss recent (2017-2020) examples of synthetic biology approaches used to address challenges in supply and contribute to structure diversification of selected plant and bacterial natural products. Our examples include plant terpenoids, alkaloids, and lignans and bacterial polyketides, nonribosomal peptides, and ribosomally synthesized and posttranslationally modified peptides.
