More than 60% of pharmaceuticals are related to natural products (NPs), chemicals produced by living organisms. Despite this fact, the rate of natural product discovery has slowed over the past few decades. In many cases the rate-limiting step in NP discovery is structural characterization. Here we report the use of microcrystal electron diffraction (MicroED), an emerging cryogenic electron microscopy (CryoEM) method, in combination with genome mining to accelerate NP discovery and structural elucidation. As powerful proofs-of-principle we rapidly determine the structure of a new 2-pyridone NP, Py-469 (1), and revise the structure of fischerin (2), an NP isolated more than 25 years ago, with potent cytotoxicity but hitherto ambiguous structural assignment. This study serves as a powerful demonstration of the synergy of MicroED and synthetic biology in NP discovery, technologies that when taken together will ultimately accelerate the rate at which new drugs are discovered.
