MetabolomicsMetabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype
The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

MetabolomicsMetabolite control of enzyme activity links stress to biosynthetic regulation

Cells must continuously adjust metabolic output to maintain homeostasis under changing environmental conditions, yet the mechanisms that enable rapid and reversible control of pathway activity remain largely unknown. The methylerythritol phosphate (MEP) pathway, of bacterial origin and conserved ...

MetabolomicsGinsenoside Rd2 improves allergic asthma by inhibiting PTGS2 enzyme activity
This study aims to elucidate the molecular mechanisms underlying the therapeutic effects of mountain-grown ginseng in allergic asthma and to systematically identify and characterize bioactive monomeric compounds responsible for these effects. We found that total saponins from mountain-grown ginseng ...

MetabolomicsInhibition of jasmonic acid-isoleucine conjugating enzyme JAR1 shifts the local and systemic leaf signals and metabolic profiles in Arabidopsis

• Jasmonates (JAs)-mediated pathways are central signaling hubs in plant defense responses. However, the identification of mobile and non-mobile signals involved in downstream systemic signaling is still less studied.

• Here, we investigate the role of the jasmonic acid-isoleucine conjugati...

MetabolomicsSerine synthesis pathway enzyme PHGDH is critical for muscle cell biomass, anabolic metabolism and mTORC1 signaling

Cells use glycolytic intermediates for anabolism e.g., via the serine synthesis and pentose phosphate pathways. However, we still understand poorly how these metabolic pathways contribute to skeletal muscle cell biomass generation. The first aim of this study was therefore to identify enzymes tha...

MetabolomicsEffect of Zanthoxylum bungeanum essential oil on rumen enzyme activity, microbiome, and metabolites in lambs

Antibiotics were once used in animal production to improve productivity and resistance to pathogenic microbiota. However, due to its negative effects, the search for a new class of substances that can replace its efficacy has become one of the urgent problems to be solved. Plant essential oils (E...

MetabolomicsThe lipid-metabolism enzyme ECI2 reduces neutrophil extracellular traps formation for colorectal cancer suppression
Abnormalities in ether lipid metabolism as well as the formation of neutrophil extracellular traps have recently been recognized as detrimental factors affecting tumorigenesis and progression. However, the role of abnormal ether lipid metabolism in colorectal cancer (CRC) evolution has not been repo...

MetabolomicsMetabolomics study for investigating the specific role of INOSITOL-REQUIRING ENZYME 1A and INOSITOL-REQUIRING ENZYME 1B under chronic endoplasmic reticulum stress in Arabidopsis thaliana

The Unfolded Protein Response (UPR) is a retrograde, ER-to-nucleus, signalling pathway which is conserved across kingdoms. In plants, it contributes to development, reproduction, immunity and tolerance to abiotic stress. This metabolomic dataset was produced from 14-day-old Arabidopsis thaliana s...

MetabolomicsB cell expression of the enzyme PexRAP, an intermediary in ether lipid biosynthesis, promotes antibody responses and germinal center size.

The qualities of antibody (Ab) responses provided by B lymphocytes and their plasma cell (PC) descendants are crucial facets of responses to vaccines and microbes. Metabolic processes and products regulate aspects of B cell proliferation and differentiation into germinal center (GC) and PC states...

MetabolomicsEnzyme engineering for optimizing biosynthesis of 2,4-dihydroxybutyric acid via the synthetic threose-dependent glycolaldehyde assimilation (STEGA) pathway
Ethylene glycol is a potential feedstock for next-generation biorefineries, as it can be derived from both plastic waste and carbon dioxide. The synthetic D-threose-dependent glycolaldehyde assimilation (STEGA) pathway, which is orthogonal to central metabolism of Escherichia coli, was recently cons...
