  • Here the authors report asperigimycins, fungal ribosomally synthesized and post-translationally modified peptides with a heptacyclic scaffold. After chemically modifying them for nanomolar anticancer activity, CRISPR screening identifies SLC46A3 as a key transporter for their uptake in cells.

  • Prenylated indole alkaloids contain spirooxindole rings with a 3R or 3S carbon stereocenter, which determines their bioactivities, but the biocatalytic mechanism controlling the 3R- or 3S-spirooxindole formation was unclear. Here, the authors report the biochemical and structural characterization of the oxygenase/semipinacolase CtdE that catalyses the 3S-spirooxindole construction in the biosynthesis of 21R-citrinadin A.

  • A Diels–Alderase that catalyses the inherently disfavoured cycloaddition and forms a bicyclo[2.2.2]diazaoctane scaffold with a strict α-anti-selectivity has now been discovered. This Diels–Alderase, called CtdP, is an NmrA-like protein. Isotopic labelling, structural biology and computational studies reveal that the CtdP-catalysed Diels–Alder reaction involves a NADP+/NADPH-dependent redox mechanism.
