This study utilizes cryo-EM to reveal the structural mechanism of CMGE biogenesis during pre-Initiation Complex assembly, demonstrating how Sld2 facilitates GINS recruitment, CMGE dimer separation, and lagging strand ejection to establish bidirectional replication forks.
By integrating symmetry analysis with ancestral sequence reconstruction, this study elucidates the evolutionary origin of the ZIP metal transporter fold, reveals a symmetric translocation pathway with defined gating mechanisms, and identifies specific residues that govern metal transport and subfamily functional specialization.
This study reveals that the C-terminal α-helix of the lipid carrier MlaC acts as a conformational switch in *Pseudomonas aeruginosa*, regulating its interaction with the MlaD hexamer and controlling phospholipid cavity accessibility to facilitate lipid transport.
This study reveals that the essential DNA repair enzyme APE1 achieves high catalytic efficiency through a novel "moving metal ion" mechanism, where orchestrated Mg2+ repositioning and a distal hydrogen-bonding network enable concerted catalysis without a pentavalent intermediate, offering new insights for designing cancer inhibitors.
This study elucidates the mechanism of the Enterococcus faecalis cytolysin toxin by presenting its first high-resolution cryo-EM structure, which reveals how its two subunits form ordered tubular assemblies to disrupt both eukaryotic and bacterial cell membranes.
The paper introduces FragDockRL, a reinforcement learning framework that combines building block assembly with tethered docking to efficiently explore synthetically constrained chemical space and prioritize high-scoring, structurally diverse ligand candidates for specific protein targets.
This study reveals that the neofunctionalized, metal-flexible superoxide dismutase (camSOD) in *Staphylococcus aureus* has evolved greater structural stability and a larger, more exchange-resistant core compared to its ancestral manganese-dependent counterpart, indicating that distinct biochemical properties underwent rapid, concomitant evolutionary change during the enzyme's divergence.
This study establishes a sensitive, label-free workflow capable of quantifying chondroitin sulphate disaccharides from just 25 µL of human milk, overcoming previous volume limitations to enable GAG profiling from microgram samples such as neonatal salvage collections.
This study elucidates how the cysteine-rich domain (CRD) mediates divergent, isoform-specific mechanisms for RAS recruitment and RAF autoinhibition relief in CRAF and ARAF, providing new insights into the biophysical principles governing MAPK pathway activation and the impact of KRAS-targeted therapeutics.
This study elucidates the anti-inflammatory mechanism of isoliquiritigenin from *Glycyrrhiza uralensis* by demonstrating that it covalently inhibits lipocalin-type prostaglandin D2 synthase (L-PGDS) via its -unsaturated carbonyl moiety, thereby suppressing prostaglandin D2 production and interleukin-6 expression.
