The authors present Enzyme-toolkit (Enzyme-tk), a unified pipeline integrating 23 open-source tools and two novel methods (Func-e and Oligopoolio) to discover previously unknown enzymes for specific reactions, successfully identifying thermostable candidates capable of degrading man-made pollutants like DEHP and TPP.
This study reveals that condensin II activation during mitosis operates via a bipartite mechanism where the protein M18BP1 both relieves autoinhibition by the NCAPD3 tail and directly enhances DNA anchoring through a positively charged loop, thereby enabling stable chromosome organization.
This study elucidates the molecular mechanisms of the Joubert syndrome protein INPP5E by identifying its tyrosine phosphorylation-dependent interactome with growth factor signaling regulators and demonstrating its differential modulation of PDGF and TGF{beta} pathways in primary cilia.
This paper presents a computationally designed protein binder strategy that targets the autoregulatory interface between the DHX9 helicase core and its dsRBD2 domain to specifically inhibit DHX9 activity for cancer therapy, offering an efficient alternative to traditional library-based screening methods.
This paper resolves the controversy surrounding Cooperativity definitions in PROTACs and molecular glues by demonstrating that the apparent negative Cooperativity observed in "partial-embedded" models is actually an entropic penalty from restricting the exposed mass of large ligands, thereby revealing that true positive Protein-Protein Interaction (PPI) Cooperativity exists once this ligand entropy cost is subtracted.
This paper introduces Quantal PCR (quPCR), a novel calibrator-free method that determines absolute nucleic acid copy numbers at the single-molecule level by deriving an intrinsic quantal unit from the system's thermodynamic and kinetic properties.
This study utilizes comprehensive proteomic and glycomic analyses to reveal that Influenza A virus infection significantly remodels the host glycoproteome by inducing widespread desialylation via viral neuraminidase and disrupting Golgi glycoprotein flux, while simultaneously triggering a prolonged unfolded protein response that increases oligomannose glycosylation.
This study utilizes glycoproteomics, cryo-EM, and surface plasmon resonance to demonstrate that the N- and O-linked glycan shields of alphaherpesvirus gB proteins, particularly their sialic acid content, differentially modulate binding to host co-receptors MAG, PILR, and NMHC-IIA, thereby explaining the distinct tropism and infectivity patterns among HSV-1, HSV-2, and VZV.
This paper introduces an iterative sampling framework that leverages coevolutionary information and residue-specific frequencies to efficiently generate diverse, high-quality ensembles of distinct protein conformations, significantly outperforming existing methods in characterizing the structural landscapes of fold-switching proteins.
This study demonstrates that dietary cholesterol reduces systolic blood pressure and attenuates renal inflammation in stroke-prone spontaneously hypertensive rats by altering lipid profiles and suppressing the arachidonic acid-prostaglandin E2 axis, thereby providing a potential mechanistic explanation for its previously observed lifespan-extending effects in this model.
