In this paper, the structural properties of C20 and C12B8 fullerene interacting with glycine based onthree active sites of glycine and one C atom or one B atom in C12B8 were analyzed through thedensity functional theory. It was found out that the binding of glycine to C12B8 generated a complex.Our results were extremely relevant in order to identify the potential applications of functionalizedC...
Glycine decarboxylase has been successfully solubilized from pea (Pisum sativum) leaf mitochondria as an acetone powder. The enzyme was dependent on added dithiothreitol and pyridoxal phosphate for maximal activity. The enzyme preparation could catalyze the exchange of CO(2) into the carboxyl carbon of glycine, the reverse of the glycine decarboxylase reaction by converting serine, NH(4) (+), a...
In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...
1. Samples of portal venous and femoral arterial plasma and mesenteric lymph were collected from unanaesthetized rats before and during the intra-duodenal infusion of high concentrations (100 mmoljl) of glycine or glycine oligopeptides (up to and including tetraglycine). 2. There was a marked increase in the concentration of free glycine, and a small amount of diglycine was detected in all the ...
objective: polyphenol oxidase or ppo (ec 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. the objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of cysteine, ascorbic acid, citric acid, kojic acid and glycine at two different ph (6 and 7) in hawthorn. me...
1. Total RNA isolated from embryonic chick paravertebral sympathetic ganglia was used in a reverse transcription-polymerase chain reaction (RT-PCR) assay with a pair of degenerate oligonucleotide primers deduced from conserved regions of mammalian glycine receptor alpha-subunits. Three classes of cDNA were identified which encode portions of the chicken homologues of the mammalian glycine recep...
Glycine, the simplest amino acid in nature and one of the most abundant free amino acids in soil, is regarded as a model nutrient in organic nitrogen studies. To date, many studies have focused on the uptake, metabolism and distribution of organic nitrogen in plants, but few have investigated the nutritional performance of plants supplied with organic nitrogen. Lettuce (Lactuca sativa L.), one ...
Glycine is a major neurotransmitter that activates inhibitory glycine receptors and is a co-agonist for excitatory glutamatergic N-methyl-D-aspartate (NMDA) receptors. Two transporters, GLYT1 and GLYT2, regulate extracellular glycine concentrations within the CNS. Dysregulation of the extracellular glycine has been associated with hyperekplexia and nonketotic hyperglycinemia. Here, we report fo...
An essential step in understanding fast synaptic transmission is to establish the activation mechanism of synaptic receptors. The purpose of this work was to extend our detailed single-channel kinetic characterization of alpha1beta glycine channels from rat recombinant receptors to native channels from juvenile (postnatal day 12-16) rat spinal cord slices. In cell-attached patches from ventral ...
