Example sentences for: divalent
How can you use “divalent” in a sentence? Here are some example sentences to help you improve your vocabulary:
This rectification has been shown to be independent of external divalent cations [ 24 ] , and is likely due to a combination of rectification in unitary conductance [ 9 ] and voltage-dependent gating [ 24 ] . Application of a lower concentration of capsaicin (0.
E. coli RNase III is active as a homodimer, and requires a divalent metal ion (preferably Mg 2+) to hydrolyze phosphodiesters, creating 5'-phosphate, 3'-hydroxyl product termini [ 4 ] . E. coli RNase III cleaves rRNA and mRNA precursors as part of the respective maturation pathways.
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+.
The patch perfusion solutions were the same as the bath solutions, except for modified divalent and ATP concentrations as indicated for particular experiments.
Some of the RNA polymerases function as single-subunit proteins, whereas others form large complexes that consist of multiple, distinct subunits; however, in all known cases, the basic catalytic activity maps to a single polypeptide containing a characteristic metal-chelating active site [ 5 6 7 ] . Typically, active sites of polymerases contain acidic or polar residues, which coordinate divalent metal cations, most often Mg 2+.
