Example sentences for: ions

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

  • In addition to the binding sites for natural or endogenous agonists (orthosteric sites), many GPCRs have also been found to have allosteric sites [ 35 ] . These sites can bind natural ligands, as in the case of Zn ions and heparin for the dopamine and neurokinin receptors, respectively, or bind synthetic drugs such gallamine, in the case of the muscarinic receptors [ 35 ] . Binding of small molecules to these allosteric sites can modulate activity of a receptor without directly mimicking or competing out the interaction of ligands to the orthosteric sites.

  • Analogous active sites, that coordinate two metal ions, are observed in domains with similar activities, such as the classical adenylyl/guanylyl cyclases, family B DNA polymerases, pol-β fold nucleotidyl transferases, and triphosphatases or phosphoesterases of the HD and DHH superfamilies [ 11 15 19 20 ] . Consistent with these observations, both CyaB and ThTPase have been shown to require Mg 2+ions for their nucleotide cyclase and phosphatase activities [ 16 17 ] .

  • (Along with magnets and Swedish foam, ions make up the holy trinity of self-improvement.)

  • Hormonal signal transduction and steroidogenesis can be affected by changes in intracellular and extracellular concentrations of inorganic ions, cellular resting membrane potential, and cell size [ 29 30 35 54 55 56 57 58 59 ] . Blockade of 4-AP sensitive K +channels in non-nerve, non-muscle cells can lead to changes in transmembrane ion gradients, membrane potential and cell volume [ 42 60 ] . On this basis, we determined the effects of 24 h exposure to 4-AP on GC size, membrane potential and intracellular potassium ([K +] in ).

  • These estimates are in excellent agreement with the crystallographically determined secondary structure of ~40% α-helix and 30% β-structure [ 37 ] . Metal analyses on multiple preparations of wild-type L1 demonstrated that the enzyme binds 1.9 ± 0.2 Zn(II) ions per monomer (Table 2), in agreement with previous results [ 36 ] .
