In the title organic-inorganic hybrid vanadate complex, [Cu(2)V(6)O(17)(C(10)H(8)N(2))(4)](n), the Cu(II) atom is six-coordinated by two chelating 2,2'-bipyridine (bipy) ligands and two vanadate O atoms in a distorted octa-hedral geometry. Two [Cu(bipy)(2)V(3)O(8)] units are linked by a bridging O atom, which lies on an inversion center, forming a dimeric unit. The dimeric units are further con...

A high resolution crystal structure of Escherichia coli alkaline phosphatase in the presence of vanadate has been refined to 1.9 A resolution. The vanadate ion takes on a trigonal bipyramidal geometry and is covalently bound by the active site serine nucleophile. A coordinated water molecule occupies the axial position opposite the serine nucleophile, whereas the equatorial oxygen atoms of the ...

This research reports a facile ultrasonic approach for the synthesis of iron vanadate (FeVO4) nanoparticles with the aid of ammonium metavanadate (NH4VO3) and Fe(NO3)3.9H2O as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. Furthermore, to examine the solar cell application of as-synthesized iron vanadate (FeVO4) nanoparticles, FTO/TiO...

A strain of Bacillus designated TA2.A1, isolated from a thermal spring in Te Aroha, New Zealand, grew optimally at pH 9.2 and 70 degrees C. Bacillus strain TA2.A1 utilized glutamate as a sole carbon and energy source for growth, and sodium chloride (>5 mM) was an obligate requirement for growth. Growth on glutamate was inhibited by monensin and amiloride, both inhibitors that collapse the sodiu...

The response of maize (Zea mays L.) and Spartina anglica root tips to exposure to sodium chloride concentrations in the range 0 to 500 mM was investigated using 23Na and 31P nuclear magnetic resonance spectroscopy (NMR). Changes in the chemical shift of the pH-dependent 31P-NMR signals from the cytoplasmic and vacuolar orthophosphate pools were correlated with the uptake of sodium, and after al...

The 90-kDa heat-shock protein (Hsp90) is a molecular chaperone that aids the folding of nuclear hormone receptors and protein kinases. Hsp90 x protein complexes can be stabilized by molybdate and by other transition metal oxyanions such as vanadate. Our earlier findings [Csermely, P., Kajtár, J., Hollósi, M., Jalsovszky, G., Holly, S., Kahn, C. R., Gergely, P. Jr, Söti, C., Mihály, K. & Somogyi...
