Satellite tobacco necrosis virus RNA directs the ribosomal binding of methionyl-, alanyl-, and lysyl-tRNA when incubated under the appropriate conditions in the in vitro wheat embryo amino acid incorporating system. The products of the various binding reactions have been identified as methionyl-tRNA, methionyl-alanyl-tRNA, and methionyl-alanyllysyl-tRNA. This sequence corresponds to the known N...

Starting with 5-S-glutathionyl-beta-alanyl-L-dopa (1) and 5-S-glutathionyl-beta-alanyl-dopamine (2), a series of analogues with truncated glutathionyl and beta-alanyl-dopa moieties were synthesized, and their inhibitory effects on autophosphorylation and substrate phosphorylation reaction by c-Src and by epidermal growth factor receptor (EGFR) were evaluated. When the glutamyl residue was remov...

N-Acetyl-muramyl-L-alanyl-D-isoglutamine (MDP), a structurally defined fragment of bacterial peptidoglycan, stimulated significant release of previously incorporated 45Ca from fetal rat bones in tissue culture over the concentration range of 0.1 to 10.0 micrograms/ml. MDP-Stimulated bone resorption was not inhibited by the addition of the prostaglandin synthetase inhibitor indomethacin to the c...

Specific aminoacylation of the phospholipid phosphatidylglycerol (PG) with alanine (or with lysine) was shown to render various organisms less susceptible to antimicrobial agents and environmental stresses. In this study, we make use of the opportunistic pathogen Pseudomonas aeruginosa to decode ORF PA0919-dependent lipid homeostasis. Analysis of the polar lipid content of the deletion mutant Δ...

Native lipoteichoid acids from Staphylococcus aureus with D-alanine ester/phosphate molar ratios between 0.23 and 0.73 were tested for lipoteichoic acid carrier activity with poly(ribito1 phosphate) polymerase from Staphylococcus aureus H. Lipoteichoic acid with an alanine/phosphorus ratio greater than 0.7 was inactive. With decreasing substitution, lipoteichoic acid carrier activity appeared a...

BACKGROUND The effect of acute L-alanyl-L-glutamine (AG; Sustamine) ingestion on performance changes and markers of fluid regulation, immune, inflammatory, oxidative stress, and recovery was examined in response to exhaustive endurance exercise, during and in the absence of dehydration. METHODS Ten physically active males (20.8 +/- 0.6 y; 176.8 +/- 7.2 cm; 77.4 +/- 10.5 kg; 12.3 +/- 4.6% body...

dietary food stimulants decrease feeding time and wasted food. in the present study, effects of adding calcium chloride and free amino acids glutamine to diet on food intake, growth performance and carcass composition of common carp were investigated. the examined food samples were 9.0 mm calcium chloride, 1.0 mm amino acid glutamine 9.0 mm calcium chloride and 1.0 mm glutamine amino acid and t...

Using the Computational methods, the interaction effect  of Glutamine Amino acid on Graphene was investigated. For this purpose, the Density Functional Theory) DFT (in the ground state of 6-31G was used, and the interaction effects of Glutamine on Graphene was investigated through attachment to two different base positions. Different parameters such as energy levels, the amount of Chemical Shif...
