The role of Mg2+ ion in flavin (flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN)) recognition by RNA aptamer has been explored through steady state and time-resolved fluorescence, circular dichroism (CD), thermal melting (TM) and isothermal titration calorimetry (ITC) studies. A...

RNA sequences were analysed in the negative-ion mode with a potential of À 4 kV applied to the spray needle. LC: Sample (200 pmol RNA dis- solved in 30 ml of 20 mM EDTA solution; average injection volume: 30 ml); column (Waters XTerraMS, C18 2.5 mm; 1.0 Â 50 mm) at 21 ...
The decay time constants are correlated with the current intensity and the nature of the permeant ion, leading us to suggest that internal Mg2þ likely serves a dual role as both permeant ion and gating ligand for CorA (Fig. 2). At high intracellular Mg2þ concentration (45 mM), CorA-...

The various methods of optical absorption spectroscopy, Rutherford back-scattering, transmission electron microscopy and X-ray diffraction, have been associated to study the high-dose ion implantation (150 keV, 1017 ions cm2) phenomena in SiO4Mg2 single crystals. After thermal annealing at high ...
The effective membrane charge density was evaluated and its dependence on the permeation flux as well as the ion pattern was discussed. For predicting an actual separation of electrolytes, the experimental investigation seems necessary for the reliability and efficiency. 展开 关键词:...
Mg ion doping has favorable influence on the photoluminescence properties of ZnSiO:Mn, the optimum concentration of Mg being 0.06 mol under 147 nm excitation. The emission intensity of Zn 4 phosphors calcined in the mixture of nitrogen and hydrogen were stronger than those of the phosphors ...

A number of molecular receptors containing ruthenium(II) bipyridine moiety as fluorophore and calix[4]arene-azacrown hybrid molecule as ionophore...
Notably, the seasonal change in cellular K þ concentration was small in absolute terms (27–103 mM), and this ion thus appears to be of minor importance with respect to osmotic regulation in marine bacteria (Figure 2b) during normal growth. For cells with higher concentrations of Mg2 þ...
