Copper vanadate nanostructures were prepared via ex-situ precipitation approach in presence of Schiff-base ligand (N,N׳ -buthylenebis(acetylacetone iminato)dianion = acacbn) as a new capping agent. The effect of different Cu sources and pH on the size, morphology and size distribution of copper vanadate nanostructures was investigated. The as-prepared products were characterized using X-ray dif...

A new polymorph of copper(ii) vanadate, Cu2(VO4)(OH), containing a layered magnetic sublattice, is synthesized by a hydrothermal reaction. It displays a 3D framework based on copper(ii) oxide layers which are further connected by VO4 tetrahedra through corner-sharing {V-O-Cu} bonds in the system. The copper(ii) oxide layer is constructed by the interactions of Cu3(μ3-OH) building units. Magneti...

H(+)-pumping ATPases were detected in microsomal vesicles of oat (Avena sativa L. var Lang) roots using [(14)C]methylamine distribution or quinacrine fluorescent quenching. Methylamine (MeA) accumulation into vesicles and quinacrine quench were specifically dependent on Mg,ATP. Both activities reflected formation of a proton gradient (DeltapH) (acid inside) as carbonyl cyanide m-chlorophenylhyd...

The MNK (Menkes disease protein; ATP7A) is a major copper- transporting P-type ATPase involved in the delivery of copper to cuproenzymes in the secretory pathway and the efflux of excess copper from extrahepatic tissues. Mutations in the MNK (ATP7A) gene result in Menkes disease, a fatal neurodegenerative copper deficiency disorder. Currently, detailed biochemical and biophysical analyses of MN...

Vanadate is a phosphate analogue that inhibits enzymes involved in phosphate release and transfer reactions (Simons, T. J. B. (1979) Nature 281, 337-338). Since such reactions may play important roles in endocytosis, we studied the effects of vanadate on various steps in receptor-mediated endocytosis of asialoorosomucoid labeled with 125I-tyramine-cellobiose (125I-TC-AOM). The labeled degradati...
