Application

Metabolomics Analysis Identifies Differential Metabolites as Biomarkers for Acute Myocardial Infarction.: Research identifies key metabolites, including L-Aspartic acid, involved in the metabolic pathways affected during acute myocardial infarction. This study enhances the understanding of biochemical changes during heart attacks, potentially leading to better diagnostic markers (Zhou et al., 2024).

Biochem/physiol Actions

Principal neurotransmisor para la excitación sináptica rápida

L-Aspartic acid is a natural proteinogenic amino acid that may be used in the formulation of cell culture media and in protein and polypeptide synthesis systems and procedures. L-Aspartic acid, an NMDA receptor agonist and non-specific glutamate receptor agonist, is used to differentiate and study the mechanisms of NMDA receptors.

Mapping Metabolic Events in the Cancer Cell Cycle Reveals Arginine Catabolism in the Committed SG2M Phase.

Irena Roci et al.

Cell reports, 26(7), 1691-1700 (2019-02-14)

Alterations in cell-cycle regulation and cellular metabolism are associated with cancer transformation, and enzymes active in the committed cell-cycle phase may represent vulnerabilities of cancer cells. Here, we map metabolic events in the G1 and SG2M phases by combining cell

Stellate Cells, Hepatocytes, and Endothelial Cells Imprint the Kupffer Cell Identity on Monocytes Colonizing the Liver Macrophage Niche.

Johnny Bonnardel et al.

Immunity, 51(4), 638-654 (2019-09-29)

Macrophages are strongly adapted to their tissue of residence. Yet, little is known about the cell-cell interactions that imprint the tissue-specific identities of macrophages in their respective niches. Using conditional depletion of liver Kupffer cells, we traced the developmental stages

Unsynchronised subunit motion in single trimeric sodium-coupled aspartate transporters.

Guus B Erkens et al.

Nature, 502(7469), 119-123 (2013-10-05)

Excitatory amino acid transporters (EAATs) are secondary transport proteins that mediate the uptake of glutamate and other amino acids. EAATs fulfil an important role in neuronal signal transmission by clearing the excitatory neurotransmitters from the synaptic cleft after depolarization of

Role of aspartate 132 at the orifice of a proton pathway in cytochrome c oxidase.

Ann-Louise Johansson et al.

Proceedings of the National Academy of Sciences of the United States of America, 110(22), 8912-8917 (2013-05-16)

Proton transfer across biological membranes underpins central processes in biological systems, such as energy conservation and transport of ions and molecules. In the membrane proteins involved in these processes, proton transfer takes place through specific pathways connecting the two sides

Chasing protons: how isothermal titration calorimetry, mutagenesis, and pKa calculations trace the locus of charge in ligand binding to a tRNA-binding enzyme.

Manuel Neeb et al.

Journal of medicinal chemistry, 57(13), 5554-5565 (2014-06-24)

Drug molecules should remain uncharged while traveling through the body and crossing membranes and should only adopt charged state upon protein binding, particularly if charge-assisted interactions can be established in deeply buried binding pockets. Such strategy requires careful pKa design
