This study presents the first crystal structures of a class C radical SAM methylase (NocN) and utilizes spectroscopic data to elucidate the structural and mechanistic basis for its catalytic role in forming the unique side-ring system of the antibiotic nosiheptide.
The paper introduces ChemCell, a non-genetic platform that utilizes metabolic installation of trans-cyclooctene groups on cell surfaces to enable rapid, selective Diels-Alder ligation for the efficient attachment of diverse large biomolecules, thereby expanding capabilities for cell-based therapies and diagnostics.
This study introduces SMART-MR1, a recombinant, miniaturized protein platform that replaces the unstable 2m and 3 domains with a stabilizing helical domain to create a stable, native-like system for MR1 ligand screening and TCR recognition studies.
This paper introduces Photoacoustic Fingerprinting (PAF), a deep learning-based framework that reframes spectral unmixing as a fingerprint recognition problem to achieve robust, quantitative molecular imaging by directly inferring concentrations from spectral shapes, thereby overcoming the limitations of conventional methods in noisy, spectrally overlapping, and fluence-distorted conditions.
This study utilizes solid-state NMR to demonstrate that chitosan is essential for maintaining the structural integrity and hydration of *Cryptococcus* cell walls, with its absence triggering distinct, species-specific remodeling of the polysaccharide network that differentially impacts *C. neoformans* and *C. gattii*.
This study demonstrates that small molecules binding to a cavity within the CLOCK PAS-A domain stabilize the protein and induce dose-dependent displacement of the CLOCK:BMAL1 complex from DNA, thereby revealing a mechanism for regulating circadian transcription factor activity through ligand occupancy.
This study elucidates the structural and dynamic mechanisms underlying rademikibart's superior potency as a second-generation IL-4Rα inhibitor compared to dupilumab, revealing that its unique binding orientation and specific interactions with the receptor's third interface loop enable more effective blockade of cytokine signaling.
This study demonstrates that in mice, plasmanyl lipids are sufficient to prevent cataracts and maintain fertility, indicating that plasmalogens are dispensable for retinal integrity and reproductive function despite their critical role in total ether lipid deficiency.
This study presents the first proteome-wide analysis revealing that mammalian proteins, including transcription factors and DNA repair enzymes, exhibit diverse and symmetry-specific recognition patterns for 5-formylcytosine modifications in CpG dyads, thereby modulating target selection and chromatin regulation.
This study elucidates how TFAM-induced promoter bending creates a transcription-stimulatory interface between PolRMT and upstream DNA, while a PolRMT tether helix acts as an autoinhibitory element to ensure promoter specificity, thereby defining the structural mechanisms governing mitochondrial transcription regulation.
