    An improved fluorescent noncanonical amino acid for measuring conformational distributions using time-resolved transition metal ion FRET

    William N Zagotta et al.
    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.

    Effects of common mutations in the SARS-CoV-2 Spike RBD and its ligand, the human ACE2 receptor on binding affinity and kinetics

    Michael I Barton et al.
    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.

    The interplay of RNA:DNA hybrid structure and G-quadruplexes determines the outcome of R-loop-replisome collisions

    Charanya Kumar et al.
    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.
