Molecular Chain Elongation Mechanism for n‐Caproate Biosynthesis by Megasphaera Hexanoica

Advanced Science, EarlyView.
The medium‐chain carboxylate‐producing microbe Megasphaera hexanoica is analyzed through genomics, transcriptomics, and metabolic engineering. The n‐caproate biosynthetic pathway is reconstructed in Escherichia coli, highlighting MhTHL as a key β‐ketothiolase. Structural analysis and mutagenesis reveal that MhTHL has a distinct substrate‐binding pocket,

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Snapshots of Coastal Ecology Using Multiproxy Analysis Reveals Insights Into the Preservation of Swamp and Marsh Environments Since the Late Pleistocene

Geochemistry, Geophysics, Geosystems
The southeastern United States Coastal Plain ecosystem contains baldcypress (Taxodium distichum) swamps and grass‐dominated marshes. These ecosystems also occurred on the exposed continental shelf during lower sea levels but are rarely preserved due to ...

Comprehensive Genetic Map of Muscle Lipidome Reveals Novel Insights Into Flavor Variation in Ruminant Meat

Advanced Science, EarlyView.
Ruminant meat is widely appreciated for its distinctive flavor. Lipids play a central role in influencing meat flavor, yet their genetic and biochemical basis remains largely unexplored. Here, a comprehensive lipid genetic map of sheep muscle is constructed and 20 candidate genes potentially modulating lipid levels are identified to provide a roadmap ...

A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate

Advanced Science, EarlyView.
Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating

Maneuvering Charge Transport via Insulating Polymer Interface for Steering Photoredox Catalysis

Advanced Science, EarlyView.
Non‐conjugated insulating polymer functions as an electron‐capturing mediator to boost interfacial charge transfer and separation, contributing to considerably enhanced photocatalytic selective organic transformation and solar CO2 conversion under visible light irradiation. Abstract Maneuvering precise and tunable charge transportation has remained the

Three‐Step Pulse Strategy Enhances Ultradilute Nitrate‐to‐Ammonia Conversion via Microenvironment and Mass Transfer Control

Advanced Science, EarlyView.
Electrochemical treatment of low‐concentration nitrate in wastewater is challenging. This study introduces a three‐step pulsed method that achieves near‐perfect efficiency in converting ultradilute nitrate to ammonia. Combined experiments and simulations reveal how pulsed strategy boost kinetics while suppressing competing reactions.
