This study demonstrates that structure-guided mutations at conserved glycine residues in *Thermosynechococcus elongatus* phycocyanin and allophycocyanin successfully inhibit hexamer formation to produce stable, homogeneous trimers, providing robust models for investigating photosynthetic energy transfer.
This study identifies KpbH as a novel PLP-dependent enzyme that catalyzes an L-aspartate-dependent decarboxylative Mannich reaction to construct the unique nonpeptidic C-C bond scaffold of the fungal neuroactive natural product kaitocephalin.
This study characterizes the ant host defense peptide abaecin-2 as a context-dependent, copper-binding effector that lacks intrinsic antibacterial activity but can synergize with other peptides to inhibit bacterial growth or protect copper-sensitive symbionts from copper toxicity, thereby enabling attine ants to differentially regulate both harmful and beneficial microbes.
This study presents the first high-resolution cryo-EM structure of the human LRRC15 receptor complexed with the therapeutic antibody samrotamab, revealing a unique lateral binding mode that preserves the receptor's signaling surface and guiding the design of new minibinders targeting the previously unexplored concave face.
This study reveals that the proteasome, via the SCF-FBXL14 E3 ligase, drives the systemic degradation of repressive transcription factors to eject TLE/Groucho co-repressors from chromatin, a mechanism essential for stem cell gene expression and cell fate specification that is disrupted by cancer-associated TLE1 mutations.
The paper introduces Q-DOAS, a sensitive and scalable proximity-quenching assay that enables real-time detection and kinetic analysis of early protein aggregation events and amyloid seeds in neurodegenerative disease models, overcoming the limitations of traditional methods like ThT.
This paper introduces DIA-QCLMS, a comprehensive data-independent acquisition framework for quantitative crosslinking mass spectrometry that integrates optimized acquisition, multi-engine spectral libraries, and a novel four-state target-decoy validation strategy to enable robust, high-confidence analysis of dynamic protein conformations and interactions.
The authors developed a streamlined cryoEM method using unpurified nuclear extracts to bypass the technical challenges of cellular thin sectioning, successfully resolving a 2.3 Å structure of nucleosomes within their native physiological environment.
The ReCap workflow, combining the Oxi-Stop cryopreservation strategy with the Oxi-DIA quantification method, enables deep, copy number-scaled cysteine redox proteomics that minimizes exogenous oxidation and reveals that redox signals are quantitatively concentrated on abundant proteins rather than being uniformly distributed.
This study demonstrates that current machine learning models and large datasets fail to accurately predict the thermal properties of extremophile enzymes due to training data biases and errors, thereby preventing a definitive assessment of the prevalence of large temperature gaps in psychrophiles.
