Biochem/physiol Actions

速いシナプス興奮を伝える主要な神経伝達物質です。

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.

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).

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

The SLC1 high-affinity glutamate and neutral amino acid transporter family.

Yoshikatsu Kanai et al.

Molecular aspects of medicine, 34(2-3), 108-120 (2013-03-20)

Glutamate transporters play important roles in the termination of excitatory neurotransmission and in providing cells throughout the body with glutamate for metabolic purposes. The high-affinity glutamate transporters EAAC1 (SLC1A1), GLT1 (SLC1A2), GLAST (SLC1A3), EAAT4 (SLC1A6), and EAAT5 (SLC1A7) mediate the

Structural basis for the drug extrusion mechanism by a MATE multidrug transporter.

Yoshiki Tanaka et al.

Nature, 496(7444), 247-251 (2013-03-29)

Multidrug and toxic compound extrusion (MATE) family transporters are conserved in the three primary domains of life (Archaea, Bacteria and Eukarya), and export xenobiotics using an electrochemical gradient of H(+) or Na(+) across the membrane. MATE transporters confer multidrug resistance

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

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
