This paper presents a cost-effective, accessible fluorometric DNA polymerase activity assay optimized for resource-limited settings through isothermal operation, in-house reagent synthesis, and stakeholder-informed design to enable local enzyme quality control and reduce dependence on imported tools.
This study utilizes cryo-electron microscopy to reveal the structural mechanisms by which the Pex2-10-12 ubiquitin ligase complex, guided by Pex8, coordinates receptor recognition, gating, and mono-ubiquitination to drive the retro-translocation and recycling of peroxisomal cargo receptors.
This study reveals that *Actinoplanes teichomyceticus* produces ferrioxamine-type siderophores with unexpected, metal-dependent antibacterial activity against Gram-positive bacteria, expanding their known biological role beyond iron acquisition.
This study elucidates a DltE-DltD-DltX interaction network in *Lactiplantibacillus plantarum* that coordinates the extracellular D-alanylation of lipoteichoic acids, a process essential for the bacterium's ability to promote *Drosophila* growth.
Using magic-angle spinning NMR spectroscopy, this study reveals that the adapter protein NUB1L binds to the N-domain of the ubiquitin-like modifier FAT10 to induce intermolecular β-sheet formation and stabilize an unfolded state, thereby acting as a holdase to facilitate FAT10-mediated proteasomal degradation during inflammation.
This study reveals that actin filaments from two evolutionarily distant yeast species exhibit significantly faster disassembly and inorganic phosphate release compared to mammalian actin due to the absence of histidine 73 methylation, while also displaying distinct biochemical and mechanical differences between the yeast species themselves.
This study elucidates the structural and biophysical basis of *Mycobacterium tuberculosis* MfpD, revealing its dimeric Roadblock/LC7-like fold and proposing a noncanonical Switch I-dependent mechanism by which it regulates MfpB GTP hydrolysis to contribute to fluoroquinolone resistance and pathogenesis.
This study utilizes the PRISMA technique combined with quantitative mass spectrometry to map high-resolution interaction surfaces of the cancer-associated protein ARID1A, successfully recapitulating known bindings while identifying novel interactors like TOX4, SIN3A, CDK2, and CCNA2, and revealing a new regulatory mechanism involving CDK2 phosphorylation that impacts cell proliferation.
This study elucidates the molecular mechanism by which the von Willebrand factor A-like domain 2 of collagen VII recognizes a Met-Gly-{Phi} motif on fibrillar collagens through specific hydrophobic interactions, thereby facilitating the transient recruitment of collagen I and III into interlaced anchoring fibrils essential for dermal-epidermal stability.
This study demonstrates that engineering a CBL mutant to mimic SLAP2-mediated activation enhances EGFR ubiquitination and degradation, thereby attenuating tyrosine kinase signaling, and validates a small-molecule screening approach to pharmacologically target this mechanism for therapeutic downregulation of tyrosine kinase pathways.
