Glutamate and reinstatement [PDF]

open access: yesCurrent Opinion in Pharmacology, 2009
The importance of glutamate in the reinstatement of cocaine-seeking behavior has been established. New molecular and neurochemical adaptations in the glutamatergic system which drive cocaine relapse have been identified, such as the ability of CB1 receptor stimulation to reduce basal glutamate levels and the involvement of the GluR1 receptor subunit in

The glutamate story [PDF]

open access: yesBritish Journal of Pharmacology, 2006
Glutamatergic synaptic transmission in the mammalian central nervous system was slowly established over a period of some 20 years, dating from the 1950s. Realisation that glutamate and like amino acids (collectively known as excitatory amino acids (EAA)) mediated their excitatory actionsviamultiple receptors preceded establishment of these receptors as

Production ofD-Glutamate fromL-Glutamate with Glutamate Racemase andL-Glutamate Oxidase [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 1999
We studied production of D-glutamate from L-glutamate using a bioreactor consisting of two columns of sequentially connected immobilized glutamate racemase (EC 5.1.1.3, from Bacillus subtilis IFO 3336) and L-glutamate oxidase (EC 1.4.3.11, from Streptomyces sp.

Enantioenriched α-substituted glutamates/pyroglutamates via enantioselective cyclopropenimine-catalyzed Michael addition of amino ester imines

open access: yesBeilstein Journal of Organic Chemistry, 2021
A procedure for the enantioselective synthesis of α-substituted glutamates and pyroglutamates via a cyclopropenimine-catalyzed Michael addition of amino ester imines is described.

Energetics of Glutamate Binding to an Ionotropic Glutamate Receptor [PDF]

open access: yesThe Journal of Physical Chemistry B, 2017
Ionotropic glutamate receptors (iGluRs) are ligand-gated ion channels that are responsible for the majority of excitatory transmission at the synaptic cleft. Mechanically speaking, agonist binding to the ligand binding domain (LBD) activates the receptor by triggering a conformational change that is transmitted to the transmembrane region, opening the ...

Effects of Antipsychotic Administration on Brain Glutamate in Schizophrenia: A Systematic Review of Longitudinal 1H-MRS Studies

open access: yesFrontiers in Psychiatry, 2017
Schizophrenia is associated with brain glutamate dysfunction, but it is currently unclear whether antipsychotic administration can reduce the extent of glutamatergic abnormality. We conducted a systematic review of proton magnetic resonance spectroscopy (

Glutamate, Glutamate Receptors, and Downstream Signaling Pathways [PDF]

open access: yesInternational Journal of Biological Sciences, 2013
Glutamate is a nonessential amino acid, a major bioenergetic substrate for proliferating normal and neoplastic cells, and an excitatory neurotransmitter that is actively involved in biosynthetic, bioenergetic, metabolic, and oncogenic signaling pathways. Glutamate signaling activates a family of receptors consisting of metabotropic glutamate receptors (

Acidic amino acids in the first intracellular loop contribute to voltage- and calcium- dependent gating of anoctamin1/TMEM16A. [PDF]

open access: yesPLoS ONE, 2014
Anoctamin1 (Ano1, or TMEM16A) is a Ca2+-activated chloride channel that is gated by both voltage and Ca2+. We have previously identified that the first intracellular loop that contains a high density of acidic residues mediates voltage- and calcium ...

Vicinal glutamates are better phosphomimetics: Phosphorylation is required for allosteric activation of guanylyl cyclase-A

open access: yesFrontiers in Molecular Neuroscience, 2022
Multisite phosphorylation of guanylyl cyclase (GC)-A, also known as NPR-A or NPR1, is required for receptor activation by natriuretic peptides (NPs) because alanine substitutions for the first four GC-A phosphorylation sites produce an enzyme that cannot

Glutamate and Epilepsy [PDF]

open access: yesThe Journal of Nutrition, 2000
Epileptic syndromes have very diverse primary causes, which may be genetic, developmental or acquired. In rodent models, altering glutamate receptor or glutamate transporter expression by knockout or knockdown procedures can induce or suppress epileptic seizures.
