Example sentences for: vanadyl

How can you use “vanadyl” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Vanadyl is unstable in aqueous solution at pH7.

  • Stock vanadyl and nucleotide solution were thawed on ice, and mixed at 1:1 molar ratio by vigorous stirring.

  • Vanadyl and nucleotide solution were prepared according to Houseman et al.

  • Vanadyl has been used to estimate the types of groups that serve as metal-ligands in F 1 -ATPase and other enzymes [ 16 18 19 21 ] because the g and A tensors of the 51V hyperfine couplings are approximately a linear combination of tensors from each type of group that contributes an equatorial ligand [ 24 27 ] . By studying the EPR spectra of bound VO 2+in the presence of different nucleotides, we show that the interaction of soluble CD39 with ATP is different from that with ADP.

  • Since the interactions of Ca +2and Mg +2with proteins are difficult to study due to the lack of spectroscopic properties, vanadyl (V IV=O) 2+has been used as a probe of the ligands that compose Mg 2+, Ca 2+, and Mn 2+binding sites of several proteins, including carboxypeptidase [ 16 ] , S-adenosylmethionine synthetase [ 17 18 ] , pyruvate kinase [ 19 20 ] , and F 1 -ATPase [ 21 22 ] . This cation specifically binds to divalent cation binding sites of several enzymes, and in many cases serves as a functional cofactor [ 23 ] . Vanadyl has one axial and four equatorial coordination sites relative to the axis of the double-bounded oxygen, an arrangement that is similar to that for Ca 2+and Mg 2+.
