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,

Onion‐Mitochondria Inhibit Lipopolysaccharide‐Induced Acute Lung Injury by Shaping Lung Macrophage Mitochondrial Function

Advanced Science, EarlyView.
Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...

Synthesis and Regulation of Folate Coenzymes During early Germination in Vigna radiata

Pteridines, 2001
Folate profiles and DNA synthesis were studied during the early germinating period in Vigna radiata. Total folate andmethyl folate forms were increased from 4 to 32 hours during germination period studied.

Coenzyme A Transferase

Journal of Biological Chemistry, 1967
Abstract The following evidence supports the conclusion that the reaction catalyzed by succinyl coenzyme A:3-keto acid coenzyme A transferase proceeds through two half-reactions in a "ping-pong" mechanism with an enzyme-CoA intermediate. (a) Double reciprocal plots of the initial rates against substrate concentration for the reaction in each direction ...

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 ...

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

Advanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

Advanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...

A Novel Regulator of Activation-Induced Cytidine Deaminase/APOBECs in Immunity and Cancer: Schrödinger’s CATalytic Pocket

Frontiers in Immunology, 2017
Activation-induced cytidine deaminase (AID) and its relative APOBEC3 cytidine deaminases boost immune response by mutating immune or viral genes. Because of their genome-mutating activities, AID/APOBECs are also drivers of tumorigenesis.

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

Advanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

RING‐Between‐RING‐Type E3 Ligase Ariadne‐Like Protein 8 Negatively Regulates Plant Virus Infection by Targeting a Viral Movement Protein

Advanced Science, EarlyView.
The plant RING‐between‐RING (RBR)‐type E3 ligase, Ariadne‐like protein 8 (ARI8), ubiquitinates and degrades a viral movement protein, restricting virus spread. ARI8 also inhibits other triple gene block 1 (TGB1)‐containing viruses, revealing a broad‐spectrum antiviral role.
