Na NMR and 14 N NQR in Mixed Crystals Na , _ x Ag

چکیده
The 2 3 N a ( / = 3/2) N M R powder pattern for the m = 1/2 m = —1/2 transition, broadened by the second-order quadrupole interaction, was investigated in mixed crystals N a ! _ x A g x N 0 2 (x<0.16). From the intensity loss of the 2 3 N a N M R line caused by the Ag + -impurity, the range of the quadrupole interaction in the 2 3 N a N M R central line was estimated. The range comprises ionic charges approximately up to the first nearest neighbour N a + site f rom the 2 3 N a nucleus, showing a large difference compared with that obtained from the 1 4 N NQR investigation in the same system.

NMR reveals double occupancy of quinone-type ligands in the catalytic quinone binding site of the Na+-translocating NADH:Quinone oxidoreductase from Vibrio cholerae.
The sodium ion-translocating NADH:quinone oxidoreductase (Na(+)-NQR) from the pathogen Vibrio cholerae exploits the free energy liberated during oxidation of NADH with ubiquinone to pump sodium ions across the cytoplasmic membrane. The Na(+)-NQR consists of four membrane-bound subunits NqrBCDE and the peripheral NqrF and NqrA subunits. NqrA binds ubiquinone-8 as well as quinones with shorter pr...
متن کاملN NQR Study of Mixed Complexes ( NaN 0 2 ) i _ JC ( AN 0 3 ) JC : ( A = K , Na ) *
N nuclear quadrupole resonance of the system (NaN02)i_J(AN03)A. with A = K and Na in the x-range 0<x<0.5 and the temperature range 77 K < 7 < 3 6 0 K has been studied. The l N NQR frequency of NaN0 2 and its line width do not change with x, the latter fact untrasting the results of other mixed systems such as Na|_,.AgvN02. This indicates that in (NaN02)!_v(AN03)v highly mobile lattice defects e...

متن کاملLocalization of ubiquinone-8 in the Na+-pumping NADH:quinone oxidoreductase from Vibrio cholerae.
Na(+) is the second major coupling ion at membranes after protons, and many pathogenic bacteria use the sodium-motive force to their advantage. A prominent example is Vibrio cholerae, which relies on the Na(+)-pumping NADH:quinone oxidoreductase (Na(+)-NQR) as the first complex in its respiratory chain. The Na(+)-NQR is a multisubunit, membrane-embedded NADH dehydrogenase that oxidizes NADH and...
متن کاملN NQR Studies of Impurity Effects on the Local Structure of NaN02-based Mixed Systems
The influence of impurities on the N NQR lineshape of Na1_^AgcN02 and [NaN02],_,[BN03]^ (B = Na, K) at room temperature has been investigated. Carrying out spectral analysis in conjunction with classification of the local field inhomogeneities according to the structurally isomorphic, Na]_xAgxN02, and anisomorphic [NaNO^.JBNC^b systems, enabled an understanding of the microscopic nature of impu...
