This study presents the crystal structure and biochemical characterization of ORF11, a bifunctional tail-spike lysin from an *E. faecium* podovirus that uniquely combines N-acetylglucosaminidase and D,D-endopeptidase activities to facilitate bacterial cell wall degradation during infection.
This study reveals that lysosomal cysteine cathepsins catalyze reverse proteolysis to generate non-genomically templated fusion peptides, including T1D-associated autoantigens, thereby uncovering a previously unrecognized pathway for peptide diversification and immune activation.
This study establishes the first continuous in vitro FRET-based kinetic assay to characterize the cholesterolysis activity of vertebrate Sonic Hedgehog C-terminal domains, revealing their strict substrate stereospecificity, optimal zwitterionic detergent conditions, and the ability to chemically rescue a catalytic mutant with hyper-nucleophilic sterols.
This study demonstrates that replacing alcohol oxidase with alcohol dehydrogenase (Adh2) for methanol dissimilation in *Komagataella phaffii* significantly enhances carbon efficiency, biomass yield, and product titers in synthetic autotrophic strains by coupling methanol oxidation with NADH generation.
This study elucidates the structural and evolutionary mechanisms of DAF-12 coactivator recruitment in parasitic nematodes through multi-disciplinary approaches, revealing both conserved features shared with mammalian receptors and parasite-specific interactions that offer a new framework for developing antiparasitic therapies targeting this critical developmental switch.
This study reveals that four interdependent pseudoknots at the 3'-terminus of the West Nile virus genome function synergistically to regulate viral growth and sfRNA formation, with SLIV playing the dominant role, and identifies conserved tertiary motifs within this assembly as potential targets for pan-flaviviral therapeutics.
This study utilizes a multi-level proteomic analysis to investigate the molecular basis of iodine-based micro-CT contrast, finding that while specific structural proteins are rich in iodine-binding aromatic heterocyclic amino acids, no significant correlation exists between overall heterocycle enrichment and tissue-specific staining intensity.
By integrating global marine metagenomic datasets with machine learning, this study maps the biogeography and taxonomic drivers of key nitrogen metabolism pathways, revealing distinct environmental patterns that link specific microbial groups to aerobic and anaerobic processes to improve biogeochemical models.
This study elucidates the molecular determinants of ligand selectivity and sensitivity in the *Daphnia magna* dopamine-gated cation channel (Dm-DopC1) by identifying specific mutations in binding loops that govern catecholamine responsiveness and reveal the receptor's hybrid pharmacological profile, thereby providing insights into the evolutionary flexibility of pentameric ligand-gated ion channels.
By dimerizing the natural product Rocaglamide into a new ligand called BisRoc, researchers created a more potent and selective inhibitor that bridges eIF4A proteins to RNA, forming higher-order complexes that effectively suppress translation and promote stress-granule formation.
