Abstract BACKGROUND Sugar cane bagasse (SB) is a by‐product of the sugar industry, and obtained on large scale. In this paper, SB was used as source carbon for preparing magnetic nanocomposite (MCN‐SB) through one‐step hydrothermal carbonisation (HTC), in presence iron (III) nitrate. By way comparison, replaced by glucose HTC (MCN‐GLU), thermal treatment material then performed under an N 2 atm...

An RNA moiety has been shown to be involved in the conversion of Glu to delta-aminolevulinic acid (ALA), the first committed intermediate of the chlorophyll pathway. We now have evidence suggesting that in Chlamydomonas, the first reaction for converting Glu to ALA is the aminoacylation of Glu to a Glu-specific tRNA. The Glu-tRNA thus formed could be the substrate for Glu-1-semialdehyde synthes...

l-Glutamate (Glu) is the main excitatory neurotransmitter in the mammalian central nervous system, and it is involved in most aspects of normal brain function, including cognition, memory and learning, plasticity, and motor movement. Although microdialysis techniques have been used to study Glu, the slow temporal resolution of the technique may be inadequate to properly examine tonic and phasic...

The Fe3O4@SiO2@APTMS@Glu-His@V complex was prepared with modification of iron oxide magnetic nanoparticles with (3-aminopropyl) trimethoxysilane (APTMS) and glutaraldehyde-L-histidine Schiff base followed by complexation with VOSO4. Characterization of the Fe3O4@SiO2@APTMS@Glu-His@V complex was carried out by means of FTIR, XRD, SEM, EDX, TEM, AAS and VSM techniques. It was found that Fe3O4@SiO...

The bacterial antiporter GadC plays a central role in the glutamate (Glu)-dependent acid resistance system, which protects enteric bacteria against the extreme acidity of the human stomach. Upon acid shock, GadC imports Glu into the cytoplasm, where Glu decarboxylases consume a cytoplasmic proton, which ends up as a "virtual" proton in the decarboxylated product γ-aminobutyric acid (GABA) and i...

BACKGROUND Domain fusion is limited at enzyme one terminus. The issue was explored by swapping a mesophilic Aspergillus niger GH11 xylanase (Xyn) with a hyper-thermophilic Thermotoga maritima glucanase (Glu) to construct two chimeras, Xyn-Glu and Glu-Xyn, with an intention to create thermostable xylanase containing glucanase activity. RESULTS When expressed in E. coli BL21(DE3), the two chime...

Responses to rapid application of glutamic acid (Glu) and gamma-aminobutyric acid (GABA), 0.01-3 mM, were recorded by whole-cell patch clamp of cultured crab (Cardisoma carnifex) X-organ neurons. Responses peaked within 200 ms. Both Glu and GABA currents had reversal potentials that followed the Nernst Cl(-) potential when [Cl(-)](i) was varied. A Boltzmann fit to the normalized, averaged dose-...

Background: Genetic variants of endothelial nitric oxide synthase (eNOS) could influence individual susceptibility to coronary artery disease. Objective: To assess whether Glu→Asp polymorphism of the eNOS gene is associated with the occurrence and severity of angiographically defined coronary artery disease in the Italian population. Methods: Polymerase chain reaction/restriction fragment lengt...
