This study overcomes the limitations of standard computational tools like AlphaFold in modeling intrinsically disordered regions by employing an integrative approach that combines experimental crosslinking with multiple modeling techniques to elucidate the structural assembly of the human HDAC2:MIER1:MHAP1 chromatin remodeling complex.
This study presents a multi-objective engineering framework that successfully designed Brnoteplase, a next-generation thrombolytic protease with enhanced fibrin selectivity, inhibition resistance, and catalytic efficiency, demonstrating superior therapeutic efficacy and safety in vivo compared to current FDA-approved variants.
This study reveals that the progressive base-pairing of miRNA with target RNA induces conformational changes in human Ago2, specifically moving the PAZ domain to create a binding interface for CK1α, which phosphorylates the EI region to unwind the guide-target complex and facilitate efficient RISC turnover.
This study reveals that the second messenger c-di-AMP directly inactivates the K+/H+ antiporter CpaA in *Bacillus subtilis* by binding to its RCK domain, thereby challenging previous assumptions about the simplicity of c-di-AMP's regulation of bacterial potassium homeostasis.
This study establishes a human cell-free high-throughput screening platform to identify the NT-2 mycotoxin as a novel ribosomal inhibitor that binds the peptidyl transferase center and induces a dormant state in mammalian protein synthesis.
This study establishes a systematic framework linking siderophore biosynthesis to primary metabolism, demonstrating that targeted supplementation of specific precursors enhances the iron-scavenging capabilities and pathogen-suppressive activity of the beneficial bacterium *Bacillus amyloliquefaciens* against *Ralstonia solanacearum*.
This study identifies the Atlas virus family in nematodes, characterizes their unique structural and functional properties via cryo-EM, and demonstrates their potential as engineered, scalable vehicles for tissue-specific RNA delivery.
This study identifies FIKK1 as a critical kinase that phosphorylates the placental malaria adhesin VAR2CSA, thereby enhancing its binding to chondroitin sulfate A and facilitating the sequestration of *Plasmodium falciparum*-infected erythrocytes in the placenta, which highlights FIKK1 as a promising drug target for placental malaria.
This study identifies human propionyl-coenzyme A carboxylase and the PRMT5:MEP50 complex as unexpected contaminants in affinity-purified proteins from HEK293 cells, demonstrating how cryo-EM and mass spectrometry can reveal these impurities and underscoring the critical need for high resin specificity in structural biology workflows.
This study demonstrates that structure-based docking of a 2.6 billion molecule library against the Cannabinoid-2 receptor successfully identified eight diverse, potent, and subtype-selective ligand families by targeting polar orthosteric residues, with experimental validation confirming the accuracy of the docking predictions and the efficacy of subsequent structure-based optimization.
