Thiotemplated Polyketide Chain Fusion and Reductive Cyclization Build the Reactive Butenolide Core of Malleicyprol

Abstract Malleicyprol, a virulence factor of notorious animal and human pathogens of the Burkholderia pseudomallei (BP) group, features a molecular cyclopropanol warhead linked to a reactive butenolide core. Biosynthetic considerations suggested that this heterocycle was formed by the merger of two individual…

The Fatal Mushroom Neurotoxin Muscarine is Released from a Harmless Phosphorylated Precursor upon Cellular Injury

l ‐(+)‐Muscarine ( 1 )‐producing mushrooms pose a severe threat to human health as ingestion can result in circulatory collapse or even death. However, their metabolic profile is surprisingly poorly understood, including knowledge of poison release and potentially toxic congeners. In the mycelium of…

Direct α‐Hydroxy Acid Loading onto a Bacterial Thiotemplate Assembly Line via a Multienzyme Gateway

Abstract Various nonribosomal peptide synthetases (NRPSs) create structural and functional diversity by incorporating α‐hydroxy acids into peptide backbones. Trigonic acid, an unusual cyclopropanol‐substituted hydroxy acid, is the source of the molecular warhead of malleicyprol, a critical virulence…

Novel Biocatalysts from Specialized Metabolism

Enzymes are increasingly recognized as valuable (bio)catalysts that complement existing synthetic methods. However, the range of biotransformations used in the laboratory is limited. Here we give an overview on the biosynthesis‐inspired discovery of novel biocatalysts that address various synthetic challenges.…
