Xanthones produced by the filamentous fungus Aspergillus nidulans protect its sexual structures from predation by arthropods.

New findings clarify apparently conflicting results about how molecular agents that preserve protein integrity prevent harmful, dense aggregates from forming.

Time-resolved transition metal ion fluorescence resonance energy transfer using a fluorescent, noncanonical amino acid donor and metal ion acceptor measures distances and distance distributions in proteins, allowing the equilibrium distributions among conformational states to be accurately determined.

GTPBP7, NSUN4, and MTERF4 facilitate maturation of the peptidyl transferase center of the mitochondrial ribosome.

Common variants of the SARS-CoV-2 Spike protein and its ligand, the human ACE2 receptor, increase the binding affinity, suggesting that they could increase viral transmissibility.

Reconstitution of orientation-specific R-loop-replisome collisions with purified proteins reveals the differential impact of R-loop-associated RNA:DNA hybrids and G-quadruplexes on replication fork progression.

METRIS is a method that reports a mechanical readout of protein-protein interactions and due to its unique properties, it will allow many protein-protein interactions to be quantitatively measured easily that are currently laborious to measure with conventional methods.

Direct single molecule visualization of striated muscle relaxation using thin filament tightropes reveals the concerted release of myosins, with implications for models of muscle function.

An RNA enzyme is caught in the act of evolving a new structural domain within its active site, resulting in enhanced catalytic function.

The structural basis of how an enzyme differentiates chemically identical molecules unlike its homolog to channel fatty acids towards secondary metabolism is elucidated.
