Glutamine synthetase (L-glutamate:ammonia ligase; EC 6.3.1.2), an enzyme catalysing the ATP-dependent formation of glutamine from glutamate and ammonia, was detected immunocytochemically only in glial (interstitial) cells of the superficial pineal gland of the rat. The results show the important role

Glutamine synthetase (E.C. 6.3.1.2) is expressed throughout the body and plays an important role in controlling body pH and in removing ammonia from the circulation. The enzyme clears L-glutamate, the major neurotransmitter in the central nervous system, from neuronal synapses.

Mitochondrial glutamine synthetase (EC 6.3.1.2) is the primary ammonia-detoxifying enzyme in avian liver and is therefore analogous in function to carbamoyl-phosphate synthetase I (ammonia) (EC 6.3.4.16) in mammalian liver. In mammalian liver, glutamine synthetase is cytosolic and its distribution is

The initial reaction in the pathway leading to the production of indole-3-acetic acid (IAA) in plants is the reaction between chorismate and glutamine to produce anthranilate, catalysed by the enzyme anthranilate synthase (ASA; EC 4.1.3.27). Compared with non-transgenic controls, leaves

Expression of carbamoylphosphate synthetase I (CPSI; EC 6.3.4.16) was examined immunohistochemically in normal development of the mouse liver, and in testicular transplants of fetal liver fragments. CPSI started to be expressed in all hepatocytes around 15 days of gestation, and

The activity of glutamine synthetase (EC 6.3.1.2) from Escherichia coli is regulated by the cyclic adenylylation and deadenylylation of Tyr-397 in each of the enzyme's 12 identical subunits. The nitration of Tyr-397 or of the nearby Tyr-326 by peroxynitrite can

Overexpression of OsGS gene modulates oxidative stress response in rice after exposure to cadmium stress. Our results describe the features of transformants with enhanced tolerance to Cd and abiotic stresses. Glutamine synthetase (GS) (EC 6.3.1.2) is an enzyme that plays

Theanine synthesis is of interest because of the physiological and pharmacological benefits of theanine. Glutamine synthetase (GS, EC 6.3.1.2) from Pseudomonas taetrolens can be used for theanine biosynthesis. In this study, GS was immobilised in polyvinyl alcohol electrospun nanofibres, and

Glutamine synthetase [L-glutamate:ammonia ligase (ADP-forming); EC 6.3.1.2] specific activity, cellular content, mRNA abundance, and gene transcription rate increase by greater than 100-fold during adipocyte differentiation of 3T3-L1 cells. In 3T3-L1 adipocytes dexamethasone increases, whereas insulin as well as N6,O2'-dibutyryladenosine 3',5'-cyclic

In this report, 8- and 2-azidoadenosine 5'-[gamma-32P]triphosphate were used to examine cerebrospinal fluid (CSF) samples for the presence of an ATP binding protein unique to individuals with Alzheimer disease (AD). A 42-kDa ATP binding protein was found in the CSF

Identification of proteins that covalently bind acetaminophen (APAP) is essential for a clearer understanding of the hepatotoxicity that results after an APAP overdose. Birge et al. (1991) have reported that in our mouse model system a membrane-associated 44-kDa acetaminophen-binding protein

The development of hepatic glutamine synthetase (GS; EC 6.3.1.2) activity and expression was studied in 1 to 112 day old sparse-fur (spf) mutant mice, with X-linked ornithine transcarbamylase (OTC, EC 2.1.3.3.) deficiency. The spf/Y mutant mice were found to have

Glutamine synthetase (GS; EC: 6.3.1.2, L-glutamate: ammonia ligase ADP-forming) is a key enzyme in ammonium assimilation and metabolism in higher plants. In poplar, the GS family is organized in 4 groups of duplicated genes, 3 of which code for cytosolic
