This study reveals that the adaptor protein SDC-3 recruits the condensin IDC complex to *C. elegans* X chromosomes by binding to the DPY-27 subunit to relieve auto-inhibition, thereby enabling loop-extrusion activity that drives chromosome-wide transcriptional repression for dosage compensation.
This study characterizes FG214, a novel heme-binding one-component transcription factor from *Fimbriimonas ginsengisoli* that functions as a redox-regulated switch by transitioning from a monomer to a DNA-binding homodimer upon heme reduction, thereby offering a potential tool for biosensing and gene regulation.
This study reports the discovery of nitrilobacillins, a new class of ribosomally synthesized and post-translationally modified peptides (RiPPs) featuring unprecedented C-terminal nitrile groups generated by an asparagine synthetase-like enzyme, which function as cysteine protease inhibitors with warheads structurally similar to synthetic therapeutics like Paxlovid.
This study demonstrates that a modular -barrel domain swapping strategy applied to -hemolysin generates stable chimeric nanopores with tailored transport properties, significantly enhancing single-molecule sensing capabilities for nucleic acids and proteins.
This study utilizes pharmacological profiling and genomic editing to demonstrate that while DGK inhibitors like R59022 and BMS-502 exhibit paralog-specific effects on DGKalpha, effective reduction of phosphatidic acid levels during PLC signaling requires the simultaneous inhibition of both DGKalpha and phospholipase D enzymes.
This paper presents a solid-phase synthesis strategy for fluorogenic ProTide probes that enables ultrasensitive profiling of carboxypeptidase activities, revealing specific enzymatic signatures in human blood that distinguish pancreatic cancer patients from healthy controls.
Researchers discovered a novel dual thiobarbiturate-indole compound (MDOLL-0273) that selectively inhibits the chikungunya virus nsP3 macrodomain by binding to a cryptic pocket, offering a promising starting point for developing antiviral therapies against CHIKV.
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.
