  • Polymerase Bcs3, which allows the fermentation-free synthesis of Haemophilus influenzae type b capsule for vaccine development, adopts a basket-like shape with all six active sites facing the interior, creating a protected environment for catalysis.

  • Systematically culturing combinations of auxotrophic yeast mutants leads to the identification of pairs that form obligatory cross-feeding relationships, some of which are stable over time and can divide metabolic labor for biotechnological applications.

  • Lowering the levels of disease-promoting proteins is generally assumed to be beneficial. The authors developed a two-step strategy to integrate protein-level tuning, noise-aware synthetic gene circuits into a well-defined human genomic locus. This approach was used to study the effect of BACH1 levels on MDA-MB-231 human breast metastatic cells.

    • We used chemical proteomics to identify candidate protein targets of indole metabolites in mammalian cells. We discovered that microbiota-derived and synthetic aromatic monoamines can activate recruitment of β-arrestin to the orphan receptor GPRC5A. Specific microbiota species that express amino acid decarboxylases were found to produce aromatic monoamine agonists for GPRC5A.

    • A new platform for screening nucleophilic-fragment-based covalent ligands enables the identification and targeting of ligandable sulfenic acid sites, setting the stage for exploration of nucleophile-directed probe and drug development.

    • Protein stability is important for biological function, but little is known about in-cell stability. In the New Delhi metallo-β-lactamase NDM-1, enhancement of zinc binding or amino acid substitutions at the C terminus increase in-cell kinetic stability and prevent proteolysis. These findings link NDM-1-mediated resistance with its in-cell stability and physiology.

      Research Briefing
    • Tricyclic peptides have reduced conformational flexibility, making them well suited for ligand development. Researchers have now generated large combinatorial libraries of tricyclic peptides using a disulfide-directing motif. Screening these libraries discovered binders to challenging protein targets.

Chemical Biology of Microbiomes

Interspecies communication in complex microbiome environments occurs through the small molecules, peptides, and proteins produced by both the host and the microbial residents, as highlighted in this collection of recent articles from Nature Portfolio.
