Direct Selection of Functional De Novo Macrocycles for Activation of On‐Cellulo Insulin Receptor

open access: yesAngewandte Chemie, EarlyView.
A live‐cell screening platform, RaPID‐ExCells, integrates mRNA display‐derived macrocyclic peptide libraries with functional selection against native cell‐surface receptors. Application to the insulin receptor enabled de novo discovery of a macrocyclic agonist that activates endogenous signaling despite weak in vitro binding, highlighting the power of ...

One‐Step Glycoengineering of NK Cells With High‐Affinity Siglec Ligands for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study develops an engineered NmCSS enzyme with improved activity for bulky group modified sialic acids, enabling efficient synthesis of structurally diverse sialoside analogs in a single step. Glycan microarray screening identified Siglec high‐affinity ligands, which were incorporated onto natural killer (NK) cells via a one‐pot enzymatic system ...

Modular Assembly of Dynamic Polymer Networks From Heteroaffinity Cross‐Links to Multivalent Proteins

open access: yesAngewandte Chemie, EarlyView.
This study develops a method to modularly assemble oligomeric binding proteins, like streptavidin, using heterobifunctional cross‐linkers that have both a strong‐ and a weak‐affinity binding moiety. These dynamic cross‐linkers enable the assembly of polymer networks with unique meta‐stable nonequilibrium topologies, and that exhibit chemically tunable ...

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

open access: yesAdvanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

open access: yesAngewandte Chemie, EarlyView.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Novel Monoclonal Antibody Detects Small Aβ Oligomers More Sensitively Than Lecanemab in Alzheimer's Disease CSF, Serum and Culture Media

open access: yesAnnals of Neurology, EarlyView.
Objective Aqueously diffusible oligomers of the amyloid β‐protein (oAβ) are neurotoxic and play a role in neuronal dysfunction in Alzheimer's disease (AD). Accurate quantification of oAβ in brains and biofluids could be valuable for understanding and monitoring AD.
