This study elucidates the structural and mechanistic basis of asymmetric transposon end recognition and pairing by the I-F3 CRISPR-associated transposase through cryo-EM analysis, revealing a novel protein-protein interface essential for high-fidelity transposition and offering insights for engineering gene therapy tools.
This paper introduces a novel method combining Deep Visual Proteomics with a modified extraction workflow that captures genomic DNA from flowthrough and peptides from the tip, enabling cell-type-resolved spatial proteogenomic analysis of matched genome and proteome data from archival FFPE tissue.
This study presents a novel, cost-effective platform called Coated Bacterial Enzymes (CBEs) that achieves one-step purification and immobilization of recombinant enzymes via SlpA domain fusion, resulting in a biocatalyst with enhanced stability, broader pH tolerance, and improved cation resistance compared to free enzymes.
This study reveals that Cathepsin C converts the lysosomal damage agent LLOMe into amyloid fibrils and, upon membrane rupture, utilizes its endogenous dipeptidyl ligase activity to perform the first fully endogenous, non-engineered proximity labeling within the lysosome, thereby uncovering new mechanisms of lysosomal perturbation and a novel tool for studying lysosomal biology.
This study demonstrates that the MRSA resistance enzyme PBP2a functions as an RNA-binding protein in vivo, where non-specific interactions with RNA transcripts via a cleft near its active site are essential for its full oxacillin resistance activity.
This study establishes that the cofactor-promiscuous HMGR enzyme in the Lyme disease pathogen *Borrelia burgdorferi* is essential for peptidoglycan synthesis and represents a promising antibacterial target, while also revealing a previously unrecognized evolutionary link between HMGR diversity and cofactor choice.
CysNet is a novel theorem-constrained computational method that overcomes the limitations of traditional bottom-up mass spectrometry by inferring specific cysteine redox proteoform states (oxiforms) from residue-level data, thereby enabling the deepest and most detailed survey of redox variation to date.
The paper introduces SANDLE, a dual-strategy statistical tool that overcomes the limitations of existing marker-dependent and marker-free methods to provide faster, more robust, and versatile analysis of differential subcellular localization across complex experimental designs.
This study reports the synthesis, purification, and structural characterization of rhodoquinone-9 and -10 analytical standards, enabling their absolute quantification and confident identification in mammalian tissues via LC-MS/MS.
This paper introduces a method to infer ion mobility collision cross section (CCS) values directly from standard LC-Orbitrap mass spectrometry data by correcting for solvent-dependent pressure variations using internal standards, thereby enabling high-precision structural annotation of lipid isomers without requiring specialized ion mobility hardware.
