How can you use “cations” in a sentence? Here are some example sentences to help you improve your vocabulary:
Ca 2+/Mg 2+discrimination relies on the affinities of the EF-hands for these cations, which is dependent on the types of amino-acid residues in the binding loop [ 11, 13].
An intriguing question remains regarding the location of the permeation pathway for cations in AQP1 channels.
Closely spaced acidic residues that coordinate divalent cations are characteristic of the active sites of most nucleic acid polymerases, in spite of the fact that they belong to several unrelated structural folds [ 9 13 14 17 28 29 59 ] . Given that the DbDGD motif is the only set of closely spaced acidic residues shared by the RDRPs and the YRHs, it is likely to form part of the nucleotidyltransferase active site of these enzymes.
In the wild and in the laboratory, yeast are exposed to stresses such as hypo-osmotic or hyperosmotic conditions, toxic cations, heat shock and cell-cycle disruptive reagents.
NTPDases do not form phosphorylated intermediates during catalysis, a conclusion also supported by lack of vanadate sensitivity and Pi product inhibition [ 3 4 5 6 ] . The catalytic reaction appears to be irreversible and no partial reactions have been observed [ 7 8 ] . Divalent cations like Ca 2+or Mg 2+are required for activity, and maximal activity is reached when the concentrations of substrates and divalent cations are equal [ 1 ] . The specific activities of NTPDases vary over a broad range from ten thousand units for potato apyrase to less than one hundred units for chicken gizzard ecto-ATPase [ 9 10 ] . Sequence comparisons indicate that most of NTPDases contain five highly conserved regions, apyrase conserved region, ACR1 - ACR5 [ 9 11 ] . However, the catalytic sites have not been identified, although ACR1 and ACR4 have been implicated in β- and γ-phosphate binding, respectively [ 9 ] .
