Stepwise DNA unwinding gates TnpB genome-editing activity

This study reveals that the limited genome-editing activity of TnpB stems from inefficient DNA unwinding into a stable open state, and demonstrates that an optimized variant (Ymu1-WFR) enhances both in vitro cleavage and plant genome editing by stabilizing specific unwinding intermediates.

Covalent remodeling of CRBN creates a non-canonical neosubstrate interface with NTAQ1

This study demonstrates that the molecular glue degrader EM12-FS covalently remodels cereblon (CRBN) at His353 to create a novel, non-canonical interface that enables the selective recruitment and degradation of the neosubstrate NTAQ1, thereby expanding the scope of induced-proximity pharmacology through site-specific synthetic modification.

Structural basis for the unexpected activity of rifamycin B against rifampicin-resistant RNA polymerase

This study reveals the structural basis for Rifamycin B's ability to inhibit rifampicin-resistant RNA polymerase, demonstrating that its unique C-4 O-carboxymethyl group forms a stabilizing salt bridge with the enzyme that bypasses common resistance mutations, thereby identifying a new target for rational antibiotic design.

From biofilms to birth: Quantitative murburn rationale for hydrated polymer-centred biological transduction, coherence, and evolution of complex life

This paper employs the murburn framework and quantitative modeling to demonstrate that hydrated extracellular polymeric phases, ranging from biofilms to birth, function as evolutionarily conserved, phase-separated matrices that regulate stochastic diffusible reactive species to enable oxygen utilization while maintaining biological coherence and facilitating complex life processes.

Amino Acids in the RSSY Motif of Lipoyl Synthase Control Substrate Binding and Reactivity

This study demonstrates that the Arg306 and Ser308 residues within the conserved RSSY motif of lipoyl synthase are critical for substrate binding and catalytic reactivity, with the S308C mutation specifically altering the auxiliary cluster's fate to produce a high-spin monothiolated intermediate and a desaturated byproduct instead of the normal lipoyl cofactor.

Hybrid quantum-classical de novo design of MHC-binding peptides

This study presents the first end-to-end hybrid quantum-classical pipeline that leverages latent vectors from a photonic quantum processor as structured priors for a generative adversarial network, successfully enhancing the de novo design of MHC-binding peptides with improved yield and broader sequence exploration, particularly for understudied alleles, as validated by both in silico predictions and in vitro experiments.
