This study utilizes a high-density genomic SNAP DNA-binding array to comprehensively define the sequence specificity, dimeric binding mechanics, and flanking sequence influences of the transcription factor GRHL2, thereby distinguishing its direct DNA occupancy from indirect cofactor-mediated recruitment.
By integrating bulk and single-cell transcriptomic analyses, this study identifies seven vascular aging-related hub genes (including TNF, MMP9, and APOE) as key diagnostic biomarkers and immune drivers in atherosclerosis, while proposing curcumin as a potential therapeutic agent targeting these genes.
This study reveals that the accumulation of native entanglement misfolding in globular proteins is a key driver of age-associated structural changes across the *Saccharomyces cerevisiae* proteome, as these entangled regions are significantly more prone to forming long-lived, near-native misfolded states during aging.
This study demonstrates that phosphorylation of the intrinsically disordered N-terminal motif A in SIRT1, particularly at Ser27, induces structural folding into an ordered conformation that significantly enhances the enzyme's deacetylase activity.
This paper proposes a revised theoretical framework that expands the classification boundaries of cephalopod reflectin proteins to accommodate newly discovered sequence diversity across ten species, enabling more accurate identification and deeper structural-functional analysis of these dynamic optical systems.
This study identifies a novel stress-response pathway in *Mycobacterium tuberculosis* where the enzyme Rv1722 synthesizes the metabolite GABA-trehalose from accumulated GABA and trehalose under hypoxic and nitric oxide stress, representing a previously unknown metabolic adaptation to immune-imposed conditions.
This study combines X-ray crystallography and molecular dynamics simulations to reveal that the turnover of carbapenem antibiotics by OXA-48 -lactamase is regulated by a complex interplay of acyl-enzyme tautomerisation, conformational dynamics, and hydration, with the OXA-519 variant showing enhanced hydrolytic potential due to a single active-site substitution.
Selective activation of estrogen receptor beta (ER{beta}) using the agonist DPN prevents lipotoxicity and restores metabolic homeostasis in estrogen-deficient models by coordinating liver lipid remodeling, enhancing fatty acid oxidation, and improving glucose and lipid profiles.
This study identifies and characterizes flavophos, a novel phosphonate antibiotic produced by *Burkholderia* that inhibits lumazine synthase, through the heterologous expression of its biosynthetic gene cluster and the structural elucidation of a divergent DUF849 enzyme involved in its synthesis.
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.
