This study elucidates the structural basis of arsenite efflux by presenting high-resolution cryo-EM structures of the ArsB pump from *Leptospirillum ferriphilum*, revealing an inward-facing conformation where metalloid binding occurs via hydrogen bonding and is coupled to proton transport through conserved aspartate residues.
This study identifies and structurally characterizes a unique nucleic acid-binding module called PXL within the PML-1 protein, demonstrating its selective binding to G-rich single-stranded RNA and DNA motifs and its role in modulating the transcriptome to regulate gene expression and nuclear organization.
The paper introduces OptiPrime, a mechanistic machine learning model that achieves state-of-the-art, interpretable, and generalizable prediction of prime editing outcomes across various editing strategies and cell types, thereby enabling the design of efficient therapeutic edits such as the in vivo correction of a neurological disorder in mice.
This study utilizes long-read genome sequencing and AlphaFold3 structural modeling to overcome assembly challenges posed by repetitive sequences, successfully identifying and characterizing 35 distinct RTX adhesins across seven Gram-negative bacterial species to inform future strategies for blocking bacterial colonization and infection.
By developing the GATO-seq assay and utilizing cryo-EM, this study reveals that a specific nucleic acid sequence induces a unique, TFIIIS-resistant "super pause" in RNA polymerase II, which stabilizes a reversible, single-nucleotide backtracked "sidetracked" state through a threonine-lined pocket, thereby demonstrating how sequence directly encodes transcriptional pausing control.
This study introduces highly sensitive and rapid chemiluminescent probes that selectively target the ClbP enzyme, enabling the direct detection of colibactin-producing *E. coli* in complex stool samples for applications in cancer research and clinical screening.
The authors present Enzyme-toolkit (Enzyme-tk), a unified pipeline integrating 23 open-source tools and two novel methods (Func-e and Oligopoolio) to discover previously unknown enzymes for specific reactions, successfully identifying thermostable candidates capable of degrading man-made pollutants like DEHP and TPP.
This study reveals that condensin II activation during mitosis operates via a bipartite mechanism where the protein M18BP1 both relieves autoinhibition by the NCAPD3 tail and directly enhances DNA anchoring through a positively charged loop, thereby enabling stable chromosome organization.
This study elucidates the molecular mechanisms of the Joubert syndrome protein INPP5E by identifying its tyrosine phosphorylation-dependent interactome with growth factor signaling regulators and demonstrating its differential modulation of PDGF and TGF{beta} pathways in primary cilia.
This paper presents a computationally designed protein binder strategy that targets the autoregulatory interface between the DHX9 helicase core and its dsRBD2 domain to specifically inhibit DHX9 activity for cancer therapy, offering an efficient alternative to traditional library-based screening methods.
