Genome mining reveals a sporulation associated protein with ferredoxin NADP+ reductase activity in Clostridium pasteurianum: structural and kinetic characterization

This study identifies and characterizes a previously unannotated sporulation-associated protein in *Clostridium pasteurianum* as a functional ferredoxin-NADP+ reductase, revealing its unique structural features, low catalytic efficiency, and potential role in redox regulation during endospore formation through combined bioinformatic, kinetic, and structural analyses.

Structural basis for the selective inhibition of the PI3KC3-C2 complex by Rubicon in endolysosome maturation and mitophagy

This study reveals the structural mechanism by which Rubicon selectively inhibits the PI3KC3-C2 complex through a UVRAG-induced conformational change in the BECN1 BARA domain, demonstrating that disrupting this specific interaction is sufficient to restore autophagy and lysosomal function to levels comparable to Rubicon gene deletion.

Allosteric Constraints on Rewiring Inducible Repressors

This study demonstrates that the difficulty in engineering robust co-repressible transcriptional systems compared to inducible ones stems from fundamental thermodynamic constraints on allosteric free-energy landscapes, suggesting that natural co-repressible scaffolds like PurR offer superior foundations for creating ligand-activated regulators.

An architectural switch in the evolution of the γ-tubulin ring complex

This study reveals the cryo-EM structure of the *C. elegans* $\gamma$ -tubulin ring complex, demonstrating how a unique 4-spoked subunit assembly replaces conserved components to template non-canonical 11-protofilament microtubules while retaining the capacity to form 13-fold symmetric structures in vitro.

A latent hydrazone switch turns SP2509 into an optical timer of cell fate

This study demonstrates that the epigenetic inhibitor SP2509 can be converted into an optical timer of cell fate by exploiting its latent ortho-hydroxy acylhydrazone switch, which allows reversible light-controlled modulation of LSD1 activity to precisely regulate chromatin-dependent processes like senescence and apoptosis.
