metabolism
physiological function
additional information
-
melatonin secretion and D-Asp release from pinealocytes are enhanced by stimulation with noradrenaline, after which the melatonin secretion is suppressed by the action of the released D-Asp on the cells. Through this negative feedback mechanism, noradrenaline may regulate its ability to induce melatonin secretion in the pineal gland
metabolism
-
in frog tissue, D-AspO plays an essential role in modulating the D-Asp concentration, exaggerated D-Asp concentrations activate SOD1 as cytoprotective mechanism in the kidney, whereas, in the brain and in the heart, where the antioxidant action of SOD1 is limited, caspase 3 is activated, overview
metabolism
-
H2O2 is essential for the iodination of the tyrosyl residues to produce mono- and diiodotyrosine that are the precursors for the synthesis of thyroid hormones T3 and T4. interaction of endogenous D-Asp, D-AspO, and D-aspartate racemase in thyroid gland constitutes an additional biochemical pathway for the production of H2O2 and consequently for the synthesis of thyroid hormones, overview

physiological function
-
D-Asp oxidase is a FAD-containing flavoprotein that catalyzes the oxidative deamination of D-amino acids with O2 to generate the corresponding 2-oxo acids, along with H2O2 and NH3. DDO is highly specific for acidic D-amino acids, such as D-Asp, N-methyl-D-Asp, and D-Glu
physiological function
-
relevance of D-Asp and DDO to NMDA receptor-related disease, D-Asp protects against sensorimotor-gating deficits, which are observed in schizophrenic patients, overview. D-Asp is important in the development and neurogenesis of the brain
physiological function
-
relevance of D-Asp and DDO to NMDA receptor-related disease, overview. Phenotype of DDO-deficient mice, DDO-deficient mice display significant deficits in prepulse inhibition, and exhibit reduced immobility time in the Porsolt forced-swim test, a model of depression, suggesting that the genetic ablation of DDO has a specific antidepressant action, overview
physiological function
-
D-Asp is important in the development and neurogenesis of the brain. D-Asp plays a regulatory role in the synthesis and secretion of prolactin in the anterior lobe of the pituitary gland. D-Asp directly interacts with DNA and/or acts on nuclear protein(s) involved in the regulation of gene transcription, through which d-Asp controls gene expression in the hypothalamo-neurohypophyseal system
physiological function
-
in frog tissue, D-AspO plays an essential role in modulating the D-Asp concentration. Induction of oxidative stress following D-Asp exposure is primarily related to its metabolism by inducible D-AspO
physiological function
-
D-AspO plays an essential role in decreasing excessive amounts of D-Asp in frog tissues

physiological function
-
age-related changes in D-aspartate oxidase promoter methylation control extracellular D-aspartate levels and prevent precocious cell death during brain aging. The enzyme expression is critical to regulate the content of the N-methyl-D-aspartate receptor agonist D-aspartate in adulthood

DASPO plays an essential role in the assimilation of D-aspartate and acts as a detoxifying agent for D-aspartate. In the wild-type strain, the induction of ChDASPO activity strictly depends on the presence of D-aspartate and is little affected by the copresence of ammonium chloride, but it is significantly reduced by the copresence of both glucose and ammonium chloride, which, however, did not abolish the induction, allowing considerable expression of ChDASPO

DASPO plays an essential role in the assimilation of D-aspartate and acts as a detoxifying agent for D-aspartate. In the wild-type strain, the induction of ChDASPO activity strictly depends on the presence of D-aspartate and is little affected by the copresence of ammonium chloride, but it is significantly reduced by the copresence of both glucose and ammonium chloride, which, however, did not abolish the induction, allowing considerable expression of ChDASPO
